Hey man I have stock electrical and want to add a battery to the trunk for my subwoofers. Can I just buy the same exact battery that's already installed under my hood to run my car?
@@RandoManFPV No, don't install lead acid in car, poison/dangerous. You need a sealed AGM Battery in the back like amzn.to/3D2MEvp made for audio and sealed agm.
@@JacobViral2 ah thank you for helping me not poison myself haha 😆 Do I need to swap my current car battery for an AGM one if I want to add an AGM battery to my trunk? What if I could fit a second battery under the hood strictly for my subs, could I then just use a lead acid match to my current car battery?
Great timing this is where I'm at in my build I need a new battery so this video was great information about what to buy vs. what I need to power thanks.
I just bought a d6500 for under hood, they are rated for 3000/4000W on the Xs power website. I’m still learning as well, so not sure why the range. Maybe under hood versus supplemental? I’m running a sundown scv4k on two American Bass hd12s @ 1ohm, a JL audio xd400/4 @ 2ohms on doors and a Singer 270a alt, so another lithium battery for the trunk is in my future as soon as I scrape up $500 and $100 for a charger. House payment and kids come first of course! Gotta pay to play and it NEVER ends like I unknowingly promised my wife at the beginning lol 🤷♂️ I’m lucky she is cool with it (for the most part haha). Keep up the good work man!
im thinking my battery is needing upgraded. when my system hits it makes my rpms drop and the volt meter drops aswell. i have a us alternators 250amp alt. and currently only using a ct sounds at1400.1d. still have a at125.4 and at60.4 plus a dayton audio dsp and 2 viair 480 compressors for air ride to hook up
Hey i got a rockville 6000watt which its not mono amp 2ohm 1500rms and 2 12 inch dvc 650rms ea at 2ohm..im waiting on amp i have the big 3 done along with 0gauge to amp when arrives etc..my alt is 110 amps and im running a generic acid lead 12volt upfront..my question is i keep hearing if i add a 2nd batt in back agm without an isolator it will drain my main battery then im hearing i need to buy 2 of the exact same agm batterys with no isolator?im on a severe budget as we are in a motel at the moment so any advice on what to get for this amp and how to do it safe as to not KILL my main battery would be greatly appreciated..i just subbed due to your thorough explanations
🔴 How did you connect your start battery to your d4800? Did you use a battery isolator? Are they just parallel to the front battery? Does one battery drain the other? ✔
You should always do alternator first batteries don’t create amps they store it. A factory alternator has its limits. You can add more batteries but you can only charge them so fast so if your sucking everything from the alternator the batteries are gonna charge slower.
Not necessarily, it is very much possible to run a stock alt and not have issues with charging. If you have plenty of Lithium or can get double or triple what's required with a 240a alternator (for example) then a 3 minute song full tilt may very well be achieved. I'm pretty sure I just saw a guy with a pretty healthy system on stock alt on JacobViral but I could be mistaken.
Help me out if u can guy, I have 2 old skool memphis 12 mojo's on a 1500 watt memphis amp. 130amp alt, regular wal mart battery under the hood. 2 d925 xs battiers in the trunk. Both max power is 2000 amps 32ah each. Did the big 3 upgrade plus some xtra power and ground wires. Do u think I have enough amperage and volts for my system? At 1st I was clipping that's why I added more grounds and power runs.
Hi No I just bought the batteries online amzn.to/3m6VdN8 and installed with no issues. Just allowed my alternator to run at idle for about 15min before testing and using.
If you have an amp that requires 3 power and ground inputs on it do you run 3 0g power wires from your front battery to the rear battery bank? An with the grounds do you jus ground the back battety bank to the frame then the 3 grounds off the 2nd battery bank? I jus wasnt sure if i need 3 power wired from the front to back with an 8k amp
So I'm new to this and I have a question I just bought a Rockford t2s216 with a Rockford T2500-1bdCP.....do you recommend upgrading my amplifier and put one of this on the back for my amplifier.?
would replacing a stock battery with an xspower (D4800) influence voltage rate? charging went from 14.4 with stock acid battery to 13.8 for the D4800 at idle.
After watching your video I learned a lot on how to calculate amps and wattages. With me still be new to the car audio I only had one amp at the time with everything stock. After some time now have a total of three amps tweeters, Mids and Sub I'm running Active. My total RMS is roughly 1304 total = 130 amps, I still have a stock Alternator and OEM battery I've looked online to find the alternator output but couldn't find it so I just added up all the fuses and divided it by 12 and got like 170amps. So with all that being said and seeing the last bit of your video since I am under 2000 and plan to stay under that should I even get a H/O alternator and instead just get an AMG battery? Amps I am using are two RE audio SA 90.4: 4 ohms 63x4 Skar RP-1200.1D - 2 ohms: 800watts for a Sundown Zv5 12" D2 in a ported box
I would just make sure you have done the big 3(4) which I have a video on channel if you search; and upgrade agm under hood and one in the back. Xs d3400 amzn.to/31bNEyl and under hood that works would be great for you.
Thanks this helps alot. I'm powering a 8k amp in my house. I have a 100ah battery and a 100amp rv charger set to continuous power at 13v so I'm assuming I have about 1k-2k watts going into it atm. Still working out the kinks trying to figure out what I need to get full power out of this. Any suggestions
Oh my bad just realized I said all that in my comment ya for what your looking for get the 100ah battery and the 100amp rv charger it work great make sure you put cardboard or something under the batter so it don't discharge and I like to have a power switch from the battery to the amp so the battery isn't constantly powering the amp and just plug and unplug the rv charger when you wanna use it
@@bugzbunnysghost8008 the thing with my situation is that i live in europe which means every power source from the wall delivers 230v and there's no power converter for sale that brings the 230v to 12v, the only solution would be a power supply from a desktop in my case
So will upgrading my regular car battery up front,from a regular 650cca/550ca to a regular 1000ca/800cca instead of one of these "audio batteries" work as well or help? I'm still adding one of these "audio batteries" in the back for the amp tho. I just always wondered if getting a beefier regular main starting battery would help.Thank You
I love your videos my friend. I have four rockford fosgate t2 16 inch subs at 1ohm two t2500-1bdcp amps and one 320amp alternator for now. What kind of audio batteries should I get for my system?
Can you help me a bit on the wiring. How many power.wires running from front battery to back battery? Did you ground back battery from the front or to a back ground??
2 runs of power 0 gauge form front to back, doubling up is always safest. Also depends on your rms power your running if doing more then 2. Ground form alternator chassis to back is best but can just double up grounds to chassis from back area to.
Yes you can but not good to stick connected for long periods of time without driving the vehicle. Usually people use isolators but I’ve seen it fine without.
I want to get two Skar 12s Evls package and it comes with a 2000 watt amp and I have a 1600 w 4 ch amp that would do 200rms at 4ohms so that would be 3600 or 2800 watts . Would I need a new battery and a H/o alt or just a new alternator? Also would I need a 350 alt or would it need to be lower or higher?
go by the RMS Rating of the amp. Sounds like 2k rms + 800 rms so 3kish? I would definitely upgrade alternators xplicitaudio.com/product-category/alternators/?ref=3229 and a 2nd battery like this amzn.to/3HFAMA6
hey man, so im trying to do an independent alternator and battery combo for my setup, its a 320 amp alt and i was thinking of doing two xs d2400 batts to power my apocalypse 7900. do you think this will be enough to get the power out of this amp?
Hey man looks like that’s about 220ah of agm which won’t be enough to support the full amp. I would go with atleast 3 group 31 agm or a 45-60ah of lithium.
What size of battery would you recommend for my 1994 Chevy 1/2ton truck 5.7 L V-8 engine with a upgraded Mechman 280 amp . I have a 1500 watt amp and a couple of neon lights on exterior and interior
it also depends on the amp's efficiency. I have a 270a mechman and 1 battery..and my system is fine... when i replaced my bass amp with a newer brazil style amp..i started having big voltage problems...went back to the old amp.... if you have a high efficiency amp.. you can get by with weaker electricals.. thats why BIG D WHIZ at Williston labs always shows efficiency numbers when he test amps
Hey Beto if you have done the big 3/4, upgraded biggest agm under hood and a group 31(130ah+) amzn.to/3t1B9k5 or bigger as 2nd then yes should be fine. Have a voltage meter to monitor.
@@ogcisco4800 I put it in a 2010 V6 RAV4 as my primary battery. They're worth upgrading to. It cranks so much faster and easier, and my system doesn't cut voltage with this battery, which is accompanied by a Rural King battery as my secondary!
So I have a 120 stock alt with a 1200 watt amp so what rated agm would I need?? From my understanding I would do 1200 divided by 10 =120 then 120 divided by 4 = 30 then do 30 + 120 = 150
I have skars 800 watts 2-12 ‘s & have 1200 watt amp. & stock battery. & Factory alternator. But I noticed once I turn on amp my truck runs a little different than when I have the Amp off. Because I ran a toggle Switch turn off & no amp. Should I replace the battery and alternator 2009 Chevy Silverado
Would a 1200 rms system benefit from a bigger main battery like an AGM or adding a second battery? Im all stock right now with 105amp alternator in a 2001 silverado with a single 12” and an rp1200 amp at 1 ohm on a short run of 4 awg ofc. Ive had lots of small systems but am new to electrical upgrades and looking into it bc i plan on getting a smart3 soon and adding another sub. Also what about HO alternators what brand is the best value? Ive heard to stay away from factory upgrade alternators from auto parts stores. Thanks for the video it was helpful shedding some light!
Going with 3k+ rms I would definitely get upgraded alt and back battery plus upgraded under hood. Mechman droppinhzcaraudio.com/collections/mechman-alternators?sca_ref=587311.YhYQ9o1trY is great for Alts, and a group 31 agm in back amzn.to/3a9iLij
If that’s your under the hood battery, you have to also compensate for vehicle also. I would suggest atleast 2 d6500s or even a d31 group 31 in the back to support that 3.5k even with the HO alt
i mean i’m new and i need this info immediately. but what im curious of is what battery do i buy for the front of my car or the trunk? i mean will my 98 civic take any battery? just the biggest one i can find? maybe a giant truck battery? lol i’m serious though when i go to buy a big battery for my trunk, is it okay to get the biggest one available? can i use a normal battery that was in my old truck that’s brand new? truck doesn’t run anymore so yeh
I have a 2004 honda crv. Two 12s at one ohm rated for 2500rms. Stock alt, 750 cranking amps battery, and a taramp 3k. What size 2nd battery should I get ?
🔴 How did you connect your start battery to your d4800? Did you use a battery isolator? Are they just parallel to the front battery? Does one battery drain the other? ✔
Hello, I'm wondering if you cane help me out I just bought a Skar skv2-2500.1D (2,500 Watt Monoblock Car Amplifier) I was planning on buying the (EVL-2X12D4 | Dual 12" 5,000 Watt EVL Series Loaded Vented Subwoofer Enclosure) But I'm not sure how it will run in my car I was planning on buying a second battery because I would imagine my stock alternator wouldn't be enough. Basically my main 2 question are... will those subs work with my amp? And what kind of battery would I need.
That box and subs dual 4s wired down to 1 ohm on the 2500 will do GREAT. I'm guessing this box/sub amzn.to/3Pb9bea ? You will want upgraded big 3 wire done (ruclips.net/video/qNQoVGlUzCY/видео.html) , Upgraded under hood and a 2nd battery. I would suggest getting a group 31 agm amzn.to/3IjI12b
That 925 is only 32ah, I would suggest atleast 80ah of agm as secondary battery for that. More is obviously better, I suggest: amzn.to/3u1YiGu xp2000 2nd batt
Your math is way off that 6500 battery could handle more than double what u said imagine if u really needed a single 6500 for only a 1000 watts lol that is over kill
Do you go with "rated amp wattage?" or "dyno amp wattage?" I have 240A alt and 80AH AGM. you formula will be 2700 watt. I want to install 3700w rated / 5000w dyno amp. I'm shy 1000w/2300w. I might still shy on my 240a alt. I also have a Gladiator which have smart alt that seem like stuck at 13.6v. What is your thought on adding supercapacitor JP630 instead of adding LTO 6.0 (I dont have the space for bigger 2nd battery and it suppose to be adding 4000w with 240A alt).
I have a 6600 watt system, I am currently wanting to upgrade my battery(s) I have a 370amp alt, I am currently running a stock battery, what size should I get one to replace the stock battery with, also my reserve battery size?
Thank you Jacob, I just installed my new system and this video helped with my questions a lot, when I start my car I have 14.4v then while driving and adding a lot of bass I get down to around 13.4v but when I’m idling my light dim with the slaps of bass my voltage is around 12.9-13.1v .
@@_Za_Unknown I got 2 big agm batteries, and I still never play it with engine off. Leaving it on, and idle at 2000 rpm to get best result. Deff sounds like you need another battery. How many watts are you running?
@@1ohmwrecker so I have a convertible if that makes a difference and my alt has 120 A and for my battery the crank is 730 and the Ah is 120 and my amplifier is 1000 watts also just to mention I’m very new to this sound world so correct me if I’m wrong somewhere
I got a homemade 3s 12.6v 280ah lithium ion battery 18650 that I plan to use to power my skar audio evl 12s 5000. Do u think powering the subwoofers at 12.6v is gonna be a prob?. I llots of people are saying I should use a lead acid battery.
Thats how I figure it too. I get voltage drop as well because I need more power. I need a higher output alt im running an ebay 250 amp alt and its only putting out 180 at 2000 rpm and I agree about getting more batteries first. Thats what im working on now. I only have 3 115ah deep cycle batts which is not enough even with the 180amp alt. I'm trying to push 4600 watts and the vehicle I have uses alot of amps on it own, especially with the air on. You may have to give you're system a break to let the alt get the batteries back up but you can always get a high output alt later when you can afford it. My system does 150's but I know I can get more out of it with more power. Thanks for the video Jacob.
Am in the same page am currently on 160 amp alternator one kinetik 2000hc and 1 kinetik 1400hc. Running it with a orion xtr2500 on 2 american bass 1200 rms each sub.recently i just bought a taramps md8000.1 and am looking at a 250 alternator and would have to add another battery of 110 ah
Those cheap high power alts are shit. They often produce as much or slightly more power at idle than your OEM alt with much less max output. And you get max output from one of them cheap alts if you're running your engine at 50+ % RPM. Not to mention that these cheap alts also have poor voltage regulators which are slow to react and thus cause sudden battery voltage drop when your bass hits hard. I just made this stupid mistake.
@@CoreMaster111I hear you. It was definitely a waste of money. It went out on me about 4 months ago. It was all I could afford at the time but I should've held off and saved up before going that route. I wasn't sure which alt to get with all the back and fourth reviews, but I'm now running a Mechman 320 and It's been great I've so far well see. I need more AGM batteries and I'm shopping right now. Lithium is gonna have to wait for now. my voltage still fluctuates but it wont drop below 13 and thats with a song playing a low steady bass note.
I have 2 Sundown X12 dual 4s .. RMS is 1500 a sub.. I have a 3200 watt mono block amp and I have a 2000 watt 4 channel amp .. what size battery should I be looking for?
I would get a group 31 AGM amzn.to/3PiMCE1 in the back with upgraded under hood and bug 3 wire done. Also will need Need atleast 260+ amp high output alternator.
Are both of your batteries hooked together positive to positive and ground to ground or is secondary battery ran straight to alternator both should be same size and brand u have 2 different sizes does that hurt it
Shessh I’m learning an this helped out but I would double of what U have for a 10k system I have two 5k an in clipping I’m assuming because of low power
I would make sure you have upgraded agm under hood and that xp3k in back with the big 3 (ruclips.net/video/qNQoVGlUzCYP/видео.html) done and should do fine.
Can anyone help me out so if I get the exact same type of battery my car has to connect to 1 12" subwoofer at 1500wrms-3000wmax is it possible to run decent power to the sub?
What should I put in the back as an extra battery for my 2000 watt amp? I’m going for an XS power battery just don’t know what size I should get they are pretty pricy, I have a 240 amp alternator
Jus dropped the car off for the install, just wanted to know before hand if I’m good in power. Running a salt 4k and a jp234. Replaced stock battery with xs d4800, jy hp40, JS 300amp alt. also a stinger 500 amp isolator. Should be fine yeah?
Hey jacob so I still haven’t deside what to,am planning to get a 250ah alternator,now i have regular battery front and rear any suggestions on what to get
Jacob i need your advice! I have a stock alternator "140amp" that i plan on replacing for a "220amp" alternator but for now i need to get a extra battery for my car audio but not sure what size to get to push my set up. My current set up is a (bass)rockford fosgate t1500 bd amp with 2 rockford fosgate 12 t1s2 subwoofers and rockford fosgate t400x4ad with 2 6 1/2 fronts 2 3 1/2 rears and tweeters that are all rockford fosgate mids and highs. I also have a aftermarket radio and distribution power and ground blocks with 250a fuse to the power wire. I hope this helps and you can point me into the right direction
Looking into getting a system in my ‘03 Tahoe and so far have 2 SAv2 12’s wired to 1 ohm. I’m planning on getting a JP23, so my question is would a 250amp alternator and a XS Power D3400 under the hood be a enough power? Amp wires and big 3 we’ll be 0 gauge wire.
@@michaelneal7397 If you already have that, yes it should help some also but if you are still in the looks I think all matching battery cell types is best.
Honestly between those two I would go with the d3100 as a secondary battery amzn.to/2PDEDbE . Now If you did the 25ah then that would be better. Also make sure you do the big 3. Use discount code “JACOBVIRAL” if you decide to buy limitless, enjoy.
If this video is for guys that’s learning then the only real answer is to go Lithium. There is no reason you need a HO Alt for 1 12”… There isn’t a single 12” on the market that would need a HO Alt. It’s the AGM batteries that’s you’re bottleneck
But a battery is just a glorified capacitor. Once the energy is used up in both batteries (takes minutes when beating) then you are only getting alt output amperage.
Jacob viral I got a question for you man and I hope this is not to long but I will try to sum it up I have 1 12” l7 in my 2500hd it had a 1200 watt kicker amp, running zero gauge everything wired up right, great ground. My issue is, it plays perfect at about 50% volume but when you put it closer to 75/80% volume the battery gauge crashes on the dash board when the bass hits hard and the actual door speakers start to cut out and skip and of course the lights dim like crazy. Idk what the issue is Iv never had issues with my vehicles in the past doing this, I could easily put the volume at 90% and play it for 30/40 minutes on rides no issue. Man nobody can seem to find the issue but it seems like it’s just draining the truck so bad when the bass hits (hard) do you know if I should try a different battery next? Thanks man really need some help
Hey David sounds like you need a voltage meter to monitor voltage and upgraded electrical. I would get a group 34 AGM amzn.to/3FtME7z as a 2nd battery and do the BIG 3 upgrade: ruclips.net/video/qNQoVGlUzCY/видео.html
@@JacobViral2 thanks for responding so fast, man looking at your vids you def seem like you have a really good understanding of audio systems and electronics, unfortunately I’m not very mechanically inclined but I think if I give myself enough time one day and watch this vids I can get it done. I’m with you I feel it’s a power supply issue, I mean the truck litteraly crashing on the dash gauge will tell me that, in the past I had the same system In a 96 z71 and a 2006 1500 and they all had no issues playing close to peak volume/power but this truck just can’t take it past about 65% volume. Thanks for the advice and for answering so quick I will keep your Chanel and I’m sure I’ll have lots of more questions in the future. It’s just sucks to pay the money for competition grade subs and only be able to play at 65% volume lol
I'm running a 250amp power bastard alt with one under the hood xsd3400r+ big 3 all ofc 0 gauge, my power run is only 12ft and my only ground to the amp is 2ft in the trunk, I power a RFt2500bdcp no problem. The lowest I've seen my voltage drop in the city with everything running +heated seats wipers fog lights and heated steering wheel is 13.2 and that's full tilt now. Huge difference with the alt.....next I think I'm gonna try a smaller pulley and belt
Lot of different factors that will determine if you can get away with it, but the safe and reliable answer is no. The one that rests higher will get voltage taken from it(The battery that rests lower, will try to be the same as the other battery and take some of its juice to try and rest at the same voltage) slowly overtime it will drain the higher resting battery and deplete its life cycle substantially. This happens whenever the car is off. To help with this ,not fix it, you can run a battery isolater-that will help separate the batteries when The car is off. So they don’t fight each other, and when the car is on, they will be in parallel to give you the reserve capacity of both batteries. But just know that all batteries accept a charge differently from the alternator. So even Though the isolater will help to some extent, The lead acid will deplet faster more Th an likely than the agm when playing your system, and will demand more recharging more often, so the batteries will not be heating up and cooling down at The same time, nor producing their output potential at the same time, nor will they recover at the same time. Hope that helps somewhat. I’m no expert, but it’s a little I’ve picked up on over The years
Goobus TheGreat. In most cases under 1000-1200 watts rms or so, you can get away with a single battery and stock alternator. Just be sure to have solid connections for power and ground( alternator charging wire to positive battery, alternator bracket/negative casing point to the chassis of the vehicle, engine block to chassis of vehicle, and battery negative to chassis/and or engine block)-Are examples of where you want a solid path for the current to flow. As long as the current flow has sufficient wire to pass through, and it’s installed in a manner to limit resistance (connection points solid, tight and corrosion free) and protected as best you can from being punctured and/or suffer from heat damage), you shouldn’t have any problems unless your current demand is more than your alternator and battery working in tandem can keep up with. I’d personally recommend ofc. That’s just my opinion. Best of luck. “Measure ten times and cut once, not measure once and cut ten times”

Great timing this is where I'm at in my build I need a new battery so this video was great information about what to buy vs. what I need to power thanks.
Thanks for sharing your experience. Much appreciated 🙏
Your welcome glad to help
FYI Your alternator is not a source of reserve power, it is only a battery maintainer.
Good info to know brother even if it isn't spot on its a rough estimate 👍
I just bought a d6500 for under hood, they are rated for 3000/4000W on the Xs power website. I’m still learning as well, so not sure why the range. Maybe under hood versus supplemental? I’m running a sundown scv4k on two American Bass hd12s @ 1ohm, a JL audio xd400/4 @ 2ohms on doors and a Singer 270a alt, so another lithium battery for the trunk is in my future as soon as I scrape up $500 and $100 for a charger. House payment and kids come first of course! Gotta pay to play and it NEVER ends like I unknowingly promised my wife at the beginning lol 🤷♂️ I’m lucky she is cool with it (for the most part haha). Keep up the good work man!
3000 is starter main
4000 is if used as secondary battery.
@@riveralley yes 3k under the hood but in the video he is saying 860 watts

Your welcome Ann thanks for watching and subscribing!
12v X 100amp/hr equals 1200watt/hr, or 1200watts for 1hr run time. HOW EVER AGM? LEAD ACID should never be run below half their capacity.

in my 2006 Saturn Ion I have a 2000rms system. I have a cheap $100 walmart battery as main battery and a small XS battery for the system.
Lol me too I’m good tho
I have a 3000 watt system and I use a xs D4800 in the trunk and a duralast agm under the hood works pretty good also a 110 amp alternator
🔴 How did you connect your start battery to your d4800? Did you use a battery isolator? Are they just parallel to the front battery? Does one battery drain the other? ✔
So 180 amp alternator can support 2 batteries?
I read every 2k watts rms go 100 ah agm so damn thanks for that man
Good info brother!
thanks glad it helps
You should always do alternator first batteries don’t create amps they store it. A factory alternator has its limits. You can add more batteries but you can only charge them so fast so if your sucking everything from the alternator the batteries are gonna charge slower.
Facts bro
Not necessarily, it is very much possible to run a stock alt and not have issues with charging. If you have plenty of Lithium or can get double or triple what's required with a 240a alternator (for example) then a 3 minute song full tilt may very well be achieved. I'm pretty sure I just saw a guy with a pretty healthy system on stock alt on JacobViral but I could be mistaken.
Yeah the alternator is the heart of the system you can have batteries all day long but how you gone keep them up
A factory alt is made to charge 2 batteries
always upgraded your alt 1st. 250 to 300amp alt. it's super important
Biggest issue is the way he's treating the alternators power generation the same as his battery capacity.. but I mean he added well after that
Help me out if u can guy, I have 2 old skool memphis 12 mojo's on a 1500 watt memphis amp. 130amp alt, regular wal mart battery under the hood. 2 d925 xs battiers in the trunk. Both max power is 2000 amps 32ah each. Did the big 3 upgrade plus some xtra power and ground wires. Do u think I have enough amperage and volts for my system? At 1st I was clipping that's why I added more grounds and power runs.
Hey quick question 🙋♂️ do you get those XS batteries precharged? And did you also buy your own charger or did you get it charged somewhere else?
Hi No I just bought the batteries online amzn.to/3m6VdN8 and installed with no issues. Just allowed my alternator to run at idle for about 15min before testing and using.
If you have an amp that requires 3 power and ground inputs on it do you run 3 0g power wires from your front battery to the rear battery bank? An with the grounds do you jus ground the back battety bank to the frame then the 3 grounds off the 2nd battery bank? I jus wasnt sure if i need 3 power wired from the front to back with an 8k amp
This was informative :)
Thanks for watching and subscribing, glad to help 👍
Where can I find that green fan belt
Thanks man
Very informative video ,👌🏾showing ❤️ from Maryland and I’m still learning
Same here
So I'm new to this and I have a question I just bought a Rockford t2s216 with a Rockford T2500-1bdCP.....do you recommend upgrading my amplifier and put one of this on the back for my amplifier.?
Your amp is a 2,500 watt, I would focus on the electrical side with batteries, alt, and wire next and a good box.
would replacing a stock battery with an xspower (D4800) influence voltage rate? charging went from 14.4 with stock acid battery to 13.8 for the D4800 at idle.
It shouldn’t no, maybe wiring changed or issue in wiring somewhere or alt or voltage regulator ?
After watching your video I learned a lot on how to calculate amps and wattages. With me still be new to the car audio I only had one amp at the time with everything stock. After some time now have a total of three amps tweeters, Mids and Sub I'm running Active. My total RMS is roughly 1304 total = 130 amps, I still have a stock Alternator and OEM battery I've looked online to find the alternator output but couldn't find it so I just added up all the fuses and divided it by 12 and got like 170amps. So with all that being said and seeing the last bit of your video since I am under 2000 and plan to stay under that should I even get a H/O alternator and instead just get an AMG battery?
Amps I am using are two RE audio SA 90.4: 4 ohms 63x4
Skar RP-1200.1D - 2 ohms: 800watts for a Sundown Zv5 12" D2 in a ported box
I would just make sure you have done the big 3(4) which I have a video on channel if you search; and upgrade agm under hood and one in the back. Xs d3400 amzn.to/31bNEyl and under hood that works would be great for you.
Thanks this helps alot. I'm powering a 8k amp in my house. I have a 100ah battery and a 100amp rv charger set to continuous power at 13v so I'm assuming I have about 1k-2k watts going into it atm.

Oh my bad just realized I said all that in my comment ya for what your looking for get the 100ah battery and the 100amp rv charger it work great make sure you put cardboard or something under the batter so it don't discharge and I like to have a power switch from the battery to the amp so the battery isn't constantly powering the amp and just plug and unplug the rv charger when you wanna use it
@@bugzbunnysghost8008 the thing with my situation is that i live in europe which means every power source from the wall delivers 230v and there's no power converter for sale that brings the 230v to 12v, the only solution would be a power supply from a desktop in my case

I just always wondered if getting a beefier regular main starting battery would help.Thank You
It would give you slightly more battery reserve so yes but you would be best having the same type of battery cells in the whole system.
I love your videos my friend. I have four rockford fosgate t2 16 inch subs at 1ohm two t2500-1bdcp amps and one 320amp alternator for now. What kind of audio batteries should I get for my system?
3-4 group 31 AGM Batteries or 60-80ah of lithium will do. More is alway me better.
@Jacob Viral2 ok ok nice and I heard lithium is the way to go. Thankyou my friend
Can you help me a bit on the wiring. How many power.wires running from front battery to back battery? Did you ground back battery from the front or to a back ground??
2 runs of power 0 gauge form front to back, doubling up is always safest. Also depends on your rms power your running if doing more then 2. Ground form alternator chassis to back is best but can just double up grounds to chassis from back area to.
I have 2 skar eVL 12s and a wDX 2K
CAN I HA A LITTLE HELP
Ok I have a single zv5 12 d2 rated at 2000 watt rms with a salt 4K. What batteries and alternator do you recommend?
Biggest high output you can get honestly. Minimum of 270amp and go with atleast two group 31 agm: amzn.to/3uuUcRs
Quick question, can you mix different agm batteries together? For example a yellow top agm and an xs power agm?
Yes you can but not good to stick connected for long periods of time without driving the vehicle. Usually people use isolators but I’ve seen it fine without.
I have a 10,500 Stetson what can I use
But remember this is only for those types of batteries not for lithium types a 80ah will be good for 10k watts if you got a 300 amp alt or bigger
What about adding diodes to your alternator ( 120amp factory ) on top of all the same features you just explainedon this video.. what's your take?
May help little more power from alt but I would get high output upgrade
Do you have a relay on it?, doesnt a second battery require one. If not, is fusing it ok
Fuses. And I use a isolator
I want to get two Skar 12s Evls package and it comes with a 2000 watt amp and I have a 1600 w 4 ch amp that would do 200rms at 4ohms so that would be 3600 or 2800 watts . Would I need a new battery and a H/o alt or just a new alternator? Also would I need a 350 alt or would it need to be lower or higher?
go by the RMS Rating of the amp. Sounds like 2k rms + 800 rms so 3kish? I would definitely upgrade alternators xplicitaudio.com/product-category/alternators/?ref=3229 and a 2nd battery like this amzn.to/3HFAMA6
hey man, so im trying to do an independent alternator and battery combo for my setup, its a 320 amp alt and i was thinking of doing two xs d2400 batts to power my apocalypse 7900. do you think this will be enough to get the power out of this amp?
Hey man looks like that’s about 220ah of agm which won’t be enough to support the full amp. I would go with atleast 3 group 31 agm or a 45-60ah of lithium.
What size of battery would you recommend for my 1994 Chevy 1/2ton truck 5.7 L V-8 engine with a upgraded Mechman 280 amp . I have a 1500 watt amp and a couple of neon lights on exterior and interior
Group 34 agm amzn.to/46GK1g5 example would be fine
it also depends on the amp's efficiency. I have a 270a mechman and 1 battery..and my system is fine... when i replaced my bass amp with a newer brazil style amp..i started having big voltage problems...went back to the old amp.... if you have a high efficiency amp.. you can get by with weaker electricals.. thats why BIG D WHIZ at Williston labs always shows efficiency numbers when he test amps
I want to run a taramps smart 3 for bass and just a generic 4 channel amp, do you guys think a 280 amp mechman and one xs battery would be fine?
Hey Beto if you have done the big 3/4, upgraded biggest agm under hood and a group 31(130ah+) amzn.to/3t1B9k5 or bigger as 2nd then yes should be fine. Have a voltage meter to monitor.
Got a duralast gold in my 07 Silverado and a 400 amp alt mechman trying to see about a getting a second battery and which one I should go with
A Group 31 agm amzn.to/3Fi6Udf would do great, but also depends on your power for electrical needs.
I have the XS Power Battery D3100 BCI GROUP 31 and it is rated at 127 AH, RC is 273 minutes, CA @ 32° F is 1564, and the MAX AMPS is 5000.
What type of truck or car did you install this battery in ? I have a 1994 Chevy 1/2ton 5.7 engine I upgraded the alternator with a Mechman 280 amp
@@ogcisco4800 I put it in a 2010 V6 RAV4 as my primary battery. They're worth upgrading to. It cranks so much faster and easier, and my system doesn't cut voltage with this battery, which is accompanied by a Rural King battery as my secondary!
So I have a 120 stock alt with a 1200 watt amp so what rated agm would I need?? From my understanding I would do 1200 divided by 10 =120 then 120 divided by 4 = 30 then do 30 + 120 = 150
Don’t forget the vehicle use, cut out about 60-80amps from alt to your vehicle but otherwise your good.

Aftermarket systems always need upgrades electrical usually
Would a 1200 rms system benefit from a bigger main battery like an AGM or adding a second battery? Im all stock right now with 105amp alternator in a 2001 silverado with a single 12” and an rp1200 amp at 1 ohm on a short run of 4 awg ofc. Ive had lots of small systems but am new to electrical upgrades and looking into it bc i plan on getting a smart3 soon and adding another sub. Also what about HO alternators what brand is the best value? Ive heard to stay away from factory upgrade alternators from auto parts stores. Thanks for the video it was helpful shedding some light!
Brand X, Mechman, JS Alts, AutoTech and there’s more I’m sure I’m forgetting. And yes it would be beneficial :)
Going with 3k+ rms I would definitely get upgraded alt and back battery plus upgraded under hood. Mechman droppinhzcaraudio.com/collections/mechman-alternators?sca_ref=587311.YhYQ9o1trY is great for Alts, and a group 31 agm in back amzn.to/3a9iLij
I have a 3500watt amp at 1 ohm and 3000rms subs. 320 amp alternator. would the d6500 be good enough on its own or do i need another battery?

No isolator needed if some battery type just direct power all. And ground all chassis and alt chassis. No draining issues if same battery cell type
Hello, I'm wondering if you cane help me out I just bought a Skar skv2-2500.1D (2,500 Watt Monoblock Car Amplifier) I was planning on buying the (EVL-2X12D4 | Dual 12" 5,000 Watt EVL Series Loaded Vented Subwoofer Enclosure) But I'm not sure how it will run in my car I was planning on buying a second battery because I would imagine my stock alternator wouldn't be enough. Basically my main 2 question are... will those subs work with my amp? And what kind of battery would I need.
That box and subs dual 4s wired down to 1 ohm on the 2500 will do GREAT. I'm guessing this box/sub amzn.to/3Pb9bea ? You will want upgraded big 3 wire done (ruclips.net/video/qNQoVGlUzCY/видео.html) , Upgraded under hood and a 2nd battery. I would suggest getting a group 31 agm amzn.to/3IjI12b

I got a homemade 3s 12.6v 280ah lithium ion battery 18650 that I plan to use to power my skar audio evl 12s 5000. Do u think powering the subwoofers at 12.6v is gonna be a prob?. I llots of people are saying I should use a lead acid battery.
I would go with 14volt and not 12v to not have issues personally.
Do a 4s configuration much better plus the car alt will over charge a 3s configuration you'll have less ah but much better voltage and cell life
Thats how I figure it too. I get voltage drop as well because I need more power. I need a higher output alt im running an ebay 250 amp alt and its only putting out 180 at 2000 rpm and I agree about getting more batteries first. Thats what im working on now. I only have 3 115ah deep cycle batts which is not enough even with the 180amp alt. I'm trying to push 4600 watts and the vehicle I have uses alot of amps on it own, especially with the air on.
You may have to give you're system a break to let the alt get the batteries back up but you can always get a high output alt later when you can afford it. My system does 150's but I know I can get more out of it with more power. Thanks for the video Jacob.

Those cheap high power alts are shit. They often produce as much or slightly more power at idle than your OEM alt with much less max output. And you get max output from one of them cheap alts if you're running your engine at 50+ % RPM. Not to mention that these cheap alts also have poor voltage regulators which are slow to react and thus cause sudden battery voltage drop when your bass hits hard. I just made this stupid mistake.
@@CoreMaster111I hear you. It was definitely a waste of money. It went out on me about 4 months ago.

Are both of your batteries hooked together positive to positive and ground to ground or is secondary battery ran straight to alternator both should be same size and brand u have 2 different sizes does that hurt it

No a lot use lithium like 10ah per 800-1000watts. I would say more like 8-10k with HO Alt 300+amp
I’mma get a 390 amp alternator and this xs 6500 battery for my f150 2005, upgrading the system to 3,500 watts rms
Awesome will help a lot, but I would suggest a group 31 amzn.to/36yvSYS xs agm in the back as it's bigger AH rating than 65.
But a battery is just a glorified capacitor. Once the energy is used up in both batteries (takes minutes when beating) then you are only getting alt output amperage.
Hi how you doing i haved a toyota Corolla 2002 we 2 amp 1 is 1200 and 1 we 2000 plus the box bass 1500 what battery i need
Get a group 31 amzn.to/2Zp4jgV and a replacement under hood and you’ll be golden. Also do big 3. 👍
Can you run multiple agms with different amp hours like an 80 ah agm and a 95 ah agm?
Yes
You can yes long as same battery cell type
@@JacobViral2 how do i know that i have the same battery cel type?
I have a 18k watt amp and want to bump hard with the car off what battery should I get?
18k watts rms? That’s a lot of power. I would suggest a dual alt system and atleast 120ah of lithium, if agm then 6+ group 31s
Jacob viral I got a question for you man and I hope this is not to long but I will try to sum it up
I have 1 12” l7 in my 2500hd it had a 1200 watt kicker amp, running zero gauge everything wired up right, great ground.
My issue is, it plays perfect at about 50% volume but when you put it closer to 75/80% volume the battery gauge crashes on the dash board when the bass hits hard and the actual door speakers start to cut out and skip and of course the lights dim like crazy.
Idk what the issue is Iv never had issues with my vehicles in the past doing this, I could easily put the volume at 90% and play it for 30/40 minutes on rides no issue.
Man nobody can seem to find the issue but it seems like it’s just draining the truck so bad when the bass hits (hard) do you know if I should try a different battery next? Thanks man really need some help
Hey David sounds like you need a voltage meter to monitor voltage and upgraded electrical. I would get a group 34 AGM amzn.to/3FtME7z as a 2nd battery and do the BIG 3 upgrade: ruclips.net/video/qNQoVGlUzCY/видео.html
@@JacobViral2 thanks for responding so fast, man looking at your vids you def seem like you have a really good understanding of audio systems and electronics, unfortunately I’m not very mechanically inclined but I think if I give myself enough time one day and watch this vids I can get it done.
I’m with you I feel it’s a power supply issue, I mean the truck litteraly crashing on the dash gauge will tell me that, in the past I had the same system In a 96 z71 and a 2006 1500 and they all had no issues playing close to peak volume/power but this truck just can’t take it past about 65% volume. Thanks for the advice and for answering so quick I will keep your Chanel and I’m sure I’ll have lots of more questions in the future.
It’s just sucks to pay the money for competition grade subs and only be able to play at 65% volume lol
I had the same problem upgraded the 4 channel amp to 4 gauge which was on a 8 gauge problem solved
I'm running a 250amp power bastard alt with one under the hood xsd3400r+ big 3 all ofc 0 gauge, my power run is only 12ft and my only ground to the amp is 2ft in the trunk, I power a RFt2500bdcp no problem. The lowest I've seen my voltage drop in the city with everything running +heated seats wipers fog lights and heated steering wheel is 13.2 and that's full tilt now. Huge difference with the alt.....next I think I'm gonna try a smaller pulley and belt
The alt kicks ass, sound is night n day now.
nice! Thanks for watching and subscribing Jayson
Could I use my stock lead acid up front and safely put an agm battery in the trunk? Or do I need to have the same types of batteries?
Lot of different factors that will determine if you can get away with it, but the safe and reliable answer is no. The one that rests higher will get voltage taken from it(The battery that rests lower, will try to be the same as the other battery and take some of its juice to try and rest at the same voltage) slowly overtime it will drain the higher resting battery and deplete its life cycle substantially. This happens whenever the car is off. To help with this ,not fix it, you can run a battery isolater-that will help separate the batteries when The car is off. So they don’t fight each other, and when the car is on, they will be in parallel to give you the reserve capacity of both batteries. But just know that all batteries accept a charge differently from the alternator. So even Though the isolater will help to some extent, The lead acid will deplet faster more Th an likely than the agm when playing your system, and will demand more recharging more often, so the batteries will not be heating up and cooling down at The same time, nor producing their output potential at the same time, nor will they recover at the same time. Hope that helps somewhat. I’m no expert, but it’s a little I’ve picked up on over The years
3RD ERA that clears up quite a bit. Thanks for the help but for now I’ll probably just upgrade the under the hood battery to agm
You sure can. People must not know about a battery isolator.
A battery isolator will keep it separate so you don't drain your stock battery. That's how I have my civic. And have for years.
Goobus TheGreat. In most cases under 1000-1200 watts rms or so, you can get away with a single battery and stock alternator. Just be sure to have solid connections for power and ground( alternator charging wire to positive battery, alternator bracket/negative casing point to the chassis of the vehicle, engine block to chassis of vehicle, and battery negative to chassis/and or engine block)-Are examples of where you want a solid path for the current to flow. As long as the current flow has sufficient wire to pass through, and it’s installed in a manner to limit resistance (connection points solid, tight and corrosion free) and protected as best you can from being punctured and/or suffer from heat damage), you shouldn’t have any problems unless your current demand is more than your alternator and battery working in tandem can keep up with. I’d personally recommend ofc. That’s just my opinion. Best of luck.
