In my opinion you should start with H/O alternator. Alternator creates the power, batteries just store it. There's an easy formula to see how many amps you need. Take the power your Amp puts out in watts, divide by Amp efficiency(roughly 70 to 80%), divide by voltage reading. I.e. 2500w ÷ .7 ÷ 13 = 274.2 amps Your system requires 275amps to fully power itself at 2500w. That's 275 amps on top of whatever your vehicle requires to run normally. No matter how many batteries you use your stock alternator will never keep up amd you will always have large voltage drops. There will always be some slight voltage drop no matter what but set up properly it is almost nonexistent. I have a mechman 400amp alt and 1 d3400 for my 3000w system and I have zero issues. My voltage stays between 14.4 and 13.8. Hope this helps someone.
im about to change my yellow top optima for the xs power. My yellow top is 10 yrs old so its time for an upgrade also jut changed my alternator from 130 amp to 200
So I have a HP 370ALT and im wanting to upgrade my stock battery to a Full Throttle 825ft-78 AGM, should I use the same size for the 2nd battery? Will that be sufficient enough for a 6,600 watt system?
i though the letter D stands for deep cell battery which would be better of in the trunk and the S battery for the engine compartment correct me if im wrong thanks
some say "the 12V batteries the D and S series batteries are the same exact battery. Only differences are the D series has blue decals and no terminals (you can buy the 580 or 586 terminals if you want), and the S series has red decals and comes with terminals." and that S is lightweight for racing and D is heavier with more reserves for car audio.
What if I have a yellow top as my main battery and the D 3400 as my secondary I have it on a 240 alternator.car on site 15.1 full tile 14.6 never under 14
That's exactly how I'm about to run my setup. Have you done it yet and if so how's it working out for you? Only difference I have is I have a 320 amp alt but just wondering how the 2 batteries work with eachother
I have a D3400 as my primary, and a Blockshakers supplemental battery for my audio system. It's supported by a 370amp mechman alternator. I run two amplifiers. A 150wx4 4 channel, and a 3000w monoblock, both from Zapco. I have zero issues and never drop below 14 volts. The science between matched batteries is sensible as electricity works in a push pull fashion. Still, I've had no trouble whatsoever.
what amp alternator you running that with? i've got one of the d3400 in my 95 caprice with a 250amp high output alternator and i think the alternator is having trouble keeping the xs power battery charged. debating between getting a different alternator or switching out the battery to something with less watts.....
240a mechman, got 2 xs power d3400s and the alternator keeps up with my 2kw system. I also use a solar panel to keep it topped off when the truck is not in use, check my other vids for how to hook that up.
Was wondering if you could help me I'm upgrading my stereo system and they said go with the D925 battery for my car but looking at the battery it has top post connections my battery has side post terminals do you know if they sell adapters so this will work for my car and what kind of charger do I need to charge the battery correctly my car is a 1999 Z28. Hopefully you can help please send me any kind of link . Thank you
You can buy adapters at any auto parts store for under $10. For charging, under normal operation, your alternator should be enough. If the car sits for periods of time, try any trickle charger, or check out my video where i show how to use a solar panel.
@@rocbola yeah they're telling me I need to buy the xs power charger for their battery so it'll work correctly but you said my alternator should be able to charge it
Absolutely. I actually keep these batteries charged using a solar panel when i'm not driving the truck for a while. Here is my set up: ruclips.net/video/QMZSe86wsXY/видео.html&
Man, I've been filming along the way, haven't had a chance to edit. Got a mechman 240a, kenwood double din, 2 15s on a jl audio amp, 2 batteries, and so many videos filmed, but no time to edit. Busy with work and had a kid. I'll edit it when I get a chance.
You can't put batteries in parallel their "internal resistance" is always going to be different always draining from each other any Electrical Engineer will tell you that. To correct it, is you will need either a high current diodes in series to isolate each battery. Or just use "BRUTE FORCE" like you may be doing now tying them together. You need to use a high current relay to take the place of both of the batteries being in parallel with the power turned off.
I keep the batteries hooked up to a solar panel with charge regulator so they float at around 13.7 during the daytime when the sun is out. I have not had any problems with them so far.
Should have waited to install both new batteries at the same time . Now one will go bad before the other and cause issues later in their battery life .
When you said you have to wait till next pay check to get the other one thats when i hit that Subscribe button .... I feel you on that brother
0:54 next pay check.i like that. Just a regular guy like me.not all of us have $10,000 to spend on a system.all at once at least
What was you're voltage like after the 3400 was installed?

Just one battery?😳

Subscribed from this video keep doing great work. Props
thank you greatly for this video
Whats the part # for the side post i wanted to try one off those d3400 on my 03 silverado thanks
Did you make a second video about the second battery??
Which posts did you use for the uppers? The XS 580 short or tall?
Can I use a battery tender on this battery to keep it maintained while in storage ?
So I have a HP 370ALT and im wanting to upgrade my stock battery to a Full Throttle 825ft-78 AGM, should I use the same size for the 2nd battery? Will that be sufficient enough for a 6,600 watt system?
I love this guy's tools!!! Tha thimble ratchet and that crank style ratchet....no homo
i though the letter D stands for deep cell battery which would be better of in the trunk and the S battery for the engine compartment correct me if im wrong

Can't you use the red top as a second battery instead of buying another xs power battery? Both agm?

@@RYTHMICRIOT You think a 370 amp is too much for only one D3400 battery? I don't have space for a second battery
@@ramsesfelix388 No way. Go for it.
@@RYTHMICRIOT Thanks!

Mmm i remember scotty Kilmer told us to put negative first.
Can u charge a xs power battery in ur trunk with the 1 red optima under rhe hood
The under hood battery is now the same xs power d3400 that is in the back. 2 matched batteries on a 240a alternator. They both charge well.
I have a redtop in my hood n xs power ps1200l in my trunk idk if the one in my hood can charge the one in the trunk
Or do i need the special agm charger for it ?
No special charger is needed.

@@rocbola awesome thank you so much for the information I really appreciate it I'll take a look at your other video
@@rocbola yeah they're telling me I need to buy the xs power charger for their battery so it'll work correctly but you said my alternator should be able to charge it
Should of kept the optima battery up front put the xs in the back run a 00 straight to the alternator
Now I have an xs power in the back and the same one in the front. I have 1/0 running to a mechman alternator.
Do you have to charge de battery first?
Yes, is mandatory
would this be good for a solar setup?
Absolutely. I actually keep these batteries charged using a solar panel when i'm not driving the truck for a while. Here is my set up: ruclips.net/video/QMZSe86wsXY/видео.html&
Hey man is a 370 amp alternator too much for only 1 XS battery? I got no space in my truck for a second one
Wheres part 2!

@@rocbola sweet,been saving forever fir a d3400 and something always comes up haha..😑

I would always recommend buying the alternator first
Thanks Thanks Thanks
Yeah you need another alternator to support that power if u got a tru wattage amp
I would kill someone if they wiped my paint with a paper towel lol..
I thought AGM batterys could sit 2 years.
Could be. Either way, i got this one at a great price.
rocbola agreed
Shawn Patton yes
I've had them go bad in a few classic cars that aren't daily drivers. I'd only recommend them for daily or with a trickle charger like he is using.

Dick Fraser would a battery isolater work?
I keep the batteries hooked up to a solar panel with charge regulator so they float at around 13.7 during the daytime when the sun is out. I have not had any problems with them so far.

Budget build with two batteries cost $350 a piece lmfao
Get your engine rpm up to 2k to get full output from it..
1200-1400 it’s ok
What kind of ratchet is that
Gearwrench brand gimbal ratchet
@@rocbola Thanx
How many watts you using?
1800 on the bass and about 200 up front, for now. Planning on adding some more up front.
