CJ18 Posted August 24, 2013 Report Share Posted August 24, 2013 Your battery bank depends on what your Alternators charging capability is. If you have a 200a alt, figure the car is going to require about 50-65a of that and leave the rest for the audio. So now you have 135a of charging capability from that alt and the rest has to be made up by the batteries. With the bc5500 and t-600, you are going to have the possibility of drawing 6-700a of current, not saying that is exactly what they are going to draw, but they could. I always plan for the worst case scenario when planning electrical systems. The following is by no means the only way to calculate how many batteries you need, but has worked pretty well for me so far. 700a of current draw - 135 amp of alt output =565a battery support D3100- 110ah 565/110=5.13 My recommendation is 5 XS Power D3100s in the rear along with whatever size XS battery is a direct drop in under the hood. Hope this helps. 4 Quote Link to comment Share on other sites More sharing options...

CJ18 Posted August 25, 2013 Report Share Posted August 25, 2013 I have 30 XS 14v batteries just for my 14v side along with 1 D6500 and 3 D3100s for my 12v side. Your electrical system is the backbone of your build, if it is weak, then your system wont perform to its potential. 1 Quote Link to comment Share on other sites More sharing options...

Omega5002 Posted August 25, 2013 Report Share Posted August 25, 2013 Is 200 amp the biggest plug and play alt, or biggest alt period?You asked Singer about a bigger option that may bolt on, even with some metal fabrication, and external regulation? 1 Quote 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...

I have not, metal fabrication would not be a single problem for me, I'm a welder/fabricator, And I ment plug and play. Quote Link to comment Share on other sites More sharing options...
Omega5002 Posted August 25, 2013 Report Share Posted August 25, 2013 Yeah, ask Mike, if he can offer a 300 amp alt that can fit in the Accord, you won't need to have so many batteries, and being a fabricator is a good advantage.

armykyle1 Posted August 25, 2013 Report Share Posted August 25, 2013 I run 7k with 4 d3100's and I still drop pretty low. How low? I'm running four D3100's in back, D3400 up front a Mechman elite 370, powering an NS1 @.65 and I stay in the highs 13s full tilt. Lowest I've seen is 13.4ish.
