Stoddamx Posted January 22, 2014 Report Share Posted January 22, 2014 How many batteries do I need if I already have a 270 amp mechman alternator and two xs d3100 batteries in the rear for this monster amp? B2 M1U.. Link to comment Share on other sites More sharing options...
Dwn4BassAlan Posted January 22, 2014 Report Share Posted January 22, 2014 AA, AAA, C, or D batteries? And are we talking duracell / energizer quality? Or that low-end kirkland battery crap?

Miguels Posted January 22, 2014 Report Share Posted January 22, 2014 dont cheap out on electrical... 5 batteries would be okay.. im going to do 6 with a 350a and if it dont go well i will add the second alt my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
mrd6 Posted January 22, 2014 Report Share Posted January 22, 2014 Minimum I would feel comfortable with would be 4 more d3100s but even then you'll probably be dropping into the low 12s or high 11s My Build Log: http://www.stevemead...-sundown-power/ Team NorthWestSPL Link to comment Share on other sites More sharing options...
Stoddamx Posted January 22, 2014 Author Report Share Posted January 22, 2014 Yeah I was thinking 4 d3100 but I just needed some more opinions. This is minimum were talking about also. Link to comment Share on other sites More sharing options...
Swaggasaur Posted January 22, 2014 Report Share Posted January 22, 2014 i run 6 d3100's and a d1200 up front with a mechman 220 and itll keep me at 12.9-13.0 as it gets hot BHE Wall Build TEAM DC Audio TEAM XS POWER1986 Monte Carlo KMC Nova's 20"4 DC XL's W/ PSI Recones2 DC 5k'sPioneer PRS 8010 Audio Technix 6 XS Power D3100's 1 XS Power D3400 Mechman 220a Alternator Link to comment Share on other sites More sharing options...
Stoddamx Posted January 22, 2014 Author Report Share Posted January 22, 2014 But just to get it running 4 d3100s would work and it wouldn't fry? And yes I get more is going to be the most answers but I want to get this thing going and all I can get is a total of 4 for the time being.

Dwn4BassAlan Posted January 22, 2014 Report Share Posted January 22, 2014 Yeah I was thinking 4 d3100 but I just needed some more opinions. This is minimum were talking about also. I'm not gonna argue you about it, but going for the minimum is usually a bad idea. Especially on electrical. To give you the minimum, going with the assumption of loss-less power, which is literally impossible to achieve in car audio at the moment; a 270a alt @14.4V will in theory be able to provide 3,888W of power, but because you have wires, box rise, impedance, back EMF, and plenty of other things that will take an electrical draw from your power, your voltage will not stay the same and your alt will not always be putting out a full 270a continuously. You need enough batteries to provide enough reserve others have said it, and I agree at least 4 more would seem wise.

mrd6 Posted January 22, 2014 Report Share Posted January 22, 2014 If you are smart with things you should be reasonably safe with that, yes. Edit: I'm talking about 6 total My Build Log: http://www.stevemead...-sundown-power/ Team NorthWestSPL Link to comment Share on other sites More sharing options...
Stoddamx Posted January 22, 2014 Author Report Share Posted January 22, 2014 Not going to argue either just getting some peoples opinions is the best when stepping up from 4k to this monster I dug myself into a hole with. I appreciate it. Link to comment Share on other sites More sharing options...
