Can you do a video showing how to add a power cap or supercap to that WRX build? It'll be between the trunk battery and amp, but do you need to fuse it again somewhere or just run from battery to cap to amp?
those two seconds at the beginning when he didn't know he was recording so he just stood completely still.
Thought my phone was froze
🤣😂😭😭😂😂😂🤣🤣
I can to the comments just to pop my ish
Most people and actors do just this after rolling so they can edit it out. He just forgot to
Well this made me think of Michael Scott since he'd make a face like that Breaking the third wall SSSSOOOOO... now I question every single thing this man said, Time to second-guess everything and watch far too many RUclips videos for days instead of actually trying to do this and practice… just a little stitious, what can I say
Great video that really went in depth, my local audio shop told me i needed an isolator and i never fully understood why, until i saw this video
Taught me exactly what I needed to know which wasn't even in the manual. THANK YOU!
Great video. I would definitely cover the positive post on that solenoid just in case...so if something does happen you dont have to replace a fuse.
Awesome job and Great Explanation for those who doesn’t understand Isolators
Wow where were ya 3 wks ago?! I mustve watched a dozen vids before installing my isolator when i just gave up & hoped for the best. Im sure many to come will be very thankful when coming across your vid. Hope it gets pushed to the top! Great vid thanx!
Excellent video. Sometimes it's hard to find install videos as straight forward and simple as this one. Do you have any videos of how to run or connect multiple(2) amplifiers?
Good explanation, I want to add one for a truck camper, I believe there isn't much difference. Thanks.
Thanks, i'm putting my system back in next week with new batteries. That wiring is really nice.
If having 2 alternators. Is the isolator a must?
Great video!! Straight to the point and great work, thank you for your help.
Awesome video, audio, explanation, details & clarity 👍👍
Thanks for the quick concise information. I will be doing this to isolate a second battery running my inverter in my car. Currently I just have a AGM in the engine bay and a jump starter thing for when I kill it. Probably abusing this battery a little much.
Battery isolator makes a lot of sense. It's not good for a battery to dump lots of charge for a long period of time when the alternator is off, it's ok for starting the car and some light music, but when cranking the tunes with the car off it's much better to shorten the life (long and short term) of the 2nd battery compared to your cranking battery. You don't want to get stuck out in the middle of no where just because you were listening to music :)
Happened to me
I am needing experience and installing this particular item you guys are a lifesaver
This is the most helpful video yet ! Love the setup !! I have one question tho: How do you choose the fuses Amperage of your isolator ?
You want to use ohms law. If ur unsure try to match ur alternators amps at peak
Great Job, looks very Professional. You answered all my questions in this video. Thanks.👍
Great explanation and at 3:41 it was all I needed to know. I’m dissecting a solid state one on my old truck and now I see what I inherited and go from there. Saved me hours of research. Cheers!
Hey man you should do another video explaining the diode type isolators, great informational video also.
Couldn’t be explain better bro awesome work
I watched countless videos to figure this out and almost bought a vsr. Your video saved the day. Thanks
Subscribe!
That is one fine install you guys did. Thank you for teaching me about battery isolators
Very helpful! Thank you sir!!
The fuse is to protect the wire/cable so it should be placed near the source (alternator or main battery). The isolator sense the main battery voltage to determine when to turn on the charging of the secondary battery, hence the isolator should be placed close to the main battery.
Hopefully he also has a fuse upfront close to that battery lol..
@@BrokenSmokinSpokeswith the way I see this installation I'm 100 percent he does.
Clean setup 👍 thanks
Mr. Beast, with your permission I'd like to track down all the individuals that gave this video a thumbs down and ask them for a good explanation on why they did that. I'd give it all the thumbs up in the world if I could.
Good knowledge.
Great video well explained
first time viewer and wow sor u helped me learn about something i didn't know that I didn't know and thank you sir
Awesome Job man!!!
Great video, so if you need to turn on the acc for the head unit to come where would you hook up the switch wire for the isolator? Wouldn't want the circuit to connect the two batteries with car not running.
Thank you great example.
Thanks for tutorial
Isolator prevent Drains!!! FYI
Good video
Great video
THANK YOU!
Great video.. but i wonder how much amp should i get for dual 70a batteries
Can you show/ demonstrate how to wire in the cable for the ignition wire? You only talked about how to do it.
I'm doing a dual battery set up today.
I was told by an audio company that the isolator should be closer to the primary battery for it to work correctly
I've noticed your isolator is way back in the trunk.
I showed them this video and they said with any dual battery system isolators need to be closest to the primary battery.
All an isolator does is separate two batteries when the coil isn't energized. Location of that isolator between those two points does not matter. I fix more installs from shops than I'd like to admit.
Thank you
Where are you guys located? Love the video need work done on my work truck !!!
Can you run off the same ignition wire your amp is connected to for the positive switch that separates it?
Hey Provo Beast Audi Install, thanks for the informative video. Nice clean looking install.
I believe you said you use 1 gauge wire. Could you tell me what size fuse you like to use? Do you size the fuse to the load, or do you size the wire gauge to the load and size the fuse to the max recommended current?......or what has worked for you?
Thanks!
The fuse needs to be matched to the maximum amperage the wire can carry. I use 250 amp on my 0/1 awg I’m pretty sure it can carry closer to 300 amps but my amp never pulls more than 250 so that is adequate for me.
Does the manual overide bridge the batteries together if you need to use the AUX to help start the car? Or, do you need to temporaly jumper the two batteries together?
After the shop installed a Stinger Isolator for me (recommended by them), I would play my music loud while driving the car. But the next time I turn on the car, code P0603 would come on. Never had the code the week before the isolator was put in. Do you think an isolator would mess with the cars voltage? I most likely will have this removed. Batteries and Alternator reads proper Voltage. Maybe the issue has something to do with the isolator on how it is wired to the ignition?
Do you have to hook the remote wire to the fuse box ? Can I use the remote that’s going to the amp?
First off thanks for the video and the install looks good. Now, are these more of a fail safe than a necessity? I am probably going to do it because it seems like it’s the right way, but is it’s sole purpose to protect the main battery from being drawn down by the secondary battery? That should only happen if you play music with the car off, if the vehicle sits for an extended period of time, or if there is a short or parasitic draw of some sort. Correct me if I am wrong.
I have a positive wire directly from the alternator to the isolator and the other positive connection on the isolator going to the secondary battery. Will this work? Or do I have to connect the starter battery positive to one isolator post and then connect the other post on the isolator to the secondary positive? My secondary battery is not charging.
Hey Chris do you offer a unit that can charge a 24volt house battery AND the 12volt car battery? Thanks.
I'd like to install a pure sine waver inverter in the trunk of my 2017 civic ex. I'd like to be able to use a kettle which is about 700 - 1000 Watts, and to charge my electronics. How do I know what size of inverter my civic can handle? Also what gauge wire would I need to go from the batter to the trunk?
I’m some what new to audio car but know basics as in wiring subs and speakers but wanted to do a big system for my 2001 Chevy express and was wondering how you pick out a secondary battery
Does the NVX smart isolator need to be grounded to the front (starter) battery? I read a few reviews on Amazon that stated if grounded to the chassis, the isolator wouldn't switch over until dangerously low voltage when grounded to chassis? Any help is appreciated
Do you think that this amp (sub channel) can push an RE AUDIO SE x Series 15? 600 rms subwoofer
Can I run a small wire from the alternator to the isolator? I only want to combine them for the charge.
can this be used on a motorcycle by locating the battery in one of my storage boxes?
Hey can the charge cable be taken from original fuse battery ? or it is necessary from alternator ?
Question could I wire the ground from a body frame to the battery to the amp on the second battery
What size fuses are you using on everything??
if my research is correct this would allow for a lithium alongside led acid?
Is the ground coming from the 2nd battery’s post going all the way back up to the starter battery or just grounded to the chassis somewhere in the trunk. You didn’t really specify where you have the black 1/0 going is why I ask because I am getting the 14.4 - 14.6 when I first start my car, but it has been draining (depending on how long I drive on each particular trip/how long I let the car sit in between trips) anywhere from 14.6 to 13.6. I am just wondering if it would drain more if I had drove longer on the trip that had it down to 13.6? & why is it draining when I’m driving at all? Is this normal? Mind you, I still have stock alternator & have yet to do my big 3 upgrade. I’m sure that if I upgrade my alternator from the stock 150 amp to a 350 amp ($278.99 not bad right?) or if I could avoid spending the $ on the alternator & fix this another way, hence my initial question. If anyone knows why this is happening, please let me know. I’ve been searching the internet since I got this thing installed, trying to figure out what exactly is going on. I did see one thing that said the isolator will try to “even out” the voltage on both batteries, but if both of them are starting at 14.6 then what does it need to even out?! You know? Any & all correspondence would be greatly appreciated. I probably just need to go on & cop that H/O alternator, right? HEELLPPP lol
Hello there can you help me out by telling me which fuze or power did you used for the power positive that is going to turn on and off when the car turns off or ON. what cable did you choose for your Ignition+ 12V source. thank you. If you can help me out that would be terrific
🔴 Can i run a positive wire from my alternator directly to my secondary agm battery in the trunk
Does it matter which post you use for ground and ignition? Thanks in advance.
Very neat
So the is charging wire coming from the battery a separate cable from the one powering the vehicle's primary accessories?
Could you use a lead battery under the hood and have a lithium bank in the rear for an audio system and run one of these and be fine?
Great video! Is it a bad idea to trigger the solenoid with the accessory wire? Thanks!!
no, that's fine. you can actually jump it off of your amp remote wire
Running dual batteries do you next higher output alternator on a 2011 Ram 1500 5.7 hemi?
Can I run the remote wire from the ignition to the isolator and the remote from the isolator to the amp? Do I need a diode to accomplish this?
Which wire in the fuse box did u tap Into Got a Subaru as well
OK. HELP!! Question. Could I use one of these, say in the 500A configuration as a straight up solenoid or relay to switch my starting battery on and off? I have a 2000 Lincoln Navigator with the air suspension and other things that run off that battery, that within a couple few weeks, if I don't pull the ground, will drain my battery flat. Unfortunately, I don't always know if and when, so it happens far too often. If I had a switch that killed the battery, it would be far less frequent as it would be less of a hassle to do. But, would say this in 500A work as a continuous operation with 100% of my battery amperage for the vehicle flowing through it during the times I operate it? Just don't know enough.....
will the isolator drain primary battery when vehicle isn't running and not using the 2nd? i have a small drain that drains my main and can't find it. the 2nd battery is used to operate my wheelchair van ramp and power controls. it's also used to jump my van if main battery is low.
What will happen to the starter battery that is full when the alternator starts charging the secondary battery? Won't overcharge the main battery that's the question?
Since the Isolater is in the trunk can I run the ground and live wire from the amp remote wire to the isolator???
2:06 I want to install a 1500 watt inverter under the driver seat 3 feet from my starter battery and want it to offer power ONLY while car is running. I was told the cables should be very thick and solid copper back to the starter battery. Currently i have to manually turn the inverter off and on manually. Two question: 1. could i have run ground negative from the inverter to my Chasis - right now i have two 1 awg copper lines between inverter and battery ? 2. where can i usually find 12v live when car is running? Can that live line be a small gauge?
What fuse did you use in the wrx? I have the same car but can’t find a fuse that won’t give me a parasitic draw :(.
and the stereo player on which battery do you connect?
Does your car engine start faster like more voltage to the starter with this setup?
So if the alternator is charging the other battery then when your not useing your amp wouldn't it get over charged and damage the battery?
What fuse did you use? For the true ignition I can’t find mine
Is it possible to use one of these for a dual compressor set up on my air suspension?!
Get the NVX 500 amp relay for bigger systems. ✌🏽
Have a question i have a 350amp aftermarket alt. And then i have stock battery up front and lithiums in the rear for my system. I have 2 1/0 power wires coming directly from my alt to the rear. But i still get a draw when my truck ia sitting because the wire coming from my stock battery to the alt i guess drains my lithium a little. Would i use the isolater between the stock charging wire from my stock battery to the alt or between my alt to the rear batterys? And since i have multiple runs from my alt to the rear batterys would i need more then 1 isolater? Hopeing i can jst connect a isolater between the stock battery and alt and then the truck is off the isolater will stop the discharging between my stock battery and alt thus hopeing my lithiums will stay at there higher charge rate.
Hey PB can I use a 200amp battery lsolator on a Alternator off 160amp I have 2010 chevy Tahoe got two Amp and 2 12'" speakers 🔊 What do you think
Could you just use a normal remote wire for the smaller one that isn’t the ground
Was a factory alternator used or was it upgraded for this setup?
Can I use the remote wire from the amp for ignitor
Would we still need this is I always have the car on when I listen to music?
Can I use an add a circuit for the trigger wire for the isolatior?
Question Do you need to have two battery to this isolator ?
If I plan to add a solar installation to the car, how could I connect the panel here?
Can you just run the isolator remote wire to the amplifier remote wire?
Is it possible to hook up isolator and capacitor together
I think i have my small negative and positive terminals hooked opposite. Would explain alott
Hello, so I took my 17 Sierra to a local shop where I had a full sound system installed with a second battery and isolator. I noticed the shop connected my amp power wired to the primary. There was no power going from my second battery to my amps. The primary and secondary battery were connected to each other. So I decided to disconnect the power amp wire from my primary and connect it to my second battery. I would listen to my music with the vehicle off but I noticed the 4 channel amp would cut off. I took the vehicle back to the shop and told them what I noticed. Their response was that they connected the power wire from my amps to the primary because of “feed back” in other words the reason why my 4 channel amp would cut off. So I’m a little lost here. Why am I getting feed back? Why would they connect it to the primary battery and not the second battery? Any help would be very appreciative. Thanks in advance.
i think i need extra battery completely isolated from the car battery because i play music for hours with the engine off, we drink and dance on the road side so we gotta save fuel.
what is your opinion
So isolator when we have different battery sizes. Got it. :)
Do I need an isolator if I’m using a yellow top for primary and a xs power D3400 for secondary? I’ve heard some people says it’s really not necessary but I’m curious.
I hooked up a second battery and I'm not getting 14v out of it. It stays around 13v. It should read 14v plus, could I have a bad ground?
Did you run an extra fuse from you’re main battery to the isolator
