deadbroke Posted November 20, 2009 Report Share Posted November 20, 2009 i have two 300 amp alternators and two rf t4000.1bd's how can i calculate how many batteries i need? i plan on running them both at 1 ohm. for example the odyessy pc2150's Quote Link to comment Share on other sites More sharing options...
Red-navi-916 Posted November 20, 2009 Report Share Posted November 20, 2009 from what i heard at least 2 batteries per amp Quote BUILDLOG http://www.stevemeadedesigns.com/board/ind...showtopic=61862 "98crewcab"Never a POS....just always "a work in progress" lol that's how we roll bitches!!!

thehoe92 Posted November 20, 2009 Report Share Posted November 20, 2009 2 group 31's should be good per amp but that line of RF amps are pretty power hungry 4 powermaster D3100's or 4 Kinetik HC3800's Quote Wouldnt be thehoe92 without teh purple Link to comment Share on other sites More sharing options...
Marlo Stanfield Posted November 20, 2009 Report Share Posted November 20, 2009 I'd say at least 4 or 5 big batts.. Like Odyssey 2150, Northstar NSB-125, XS 3100, Kinetik 3800, etc similar performance batts. I'm running just under 9,000w after adding in my front stage amps and I'm running 2 300a Ohio Gen alts, 5 NSB-125s + NSB-75 under hood and (2) 2/0 runs per amp... I get very little voltage drop and that is mostly just during multiple bassrace runs or demos one after another. Quote 1998 Ford Explorer Eddie Bauer... New setup, old ride...

deadbroke Posted November 20, 2009 Author Report Share Posted November 20, 2009 (edited) well i have 2 of the odyssey 2150's and built a box for it already so i might be halfway there. my system is dedicated i will actually be running 3 300 amp alts but my third will power just the vehicle and a smaller odyssey battery i have. i'm running out of room for more batteries i have a feeling if i fit any more it would only be one more. this is going in my s10 and am planning on btl 15's. i seen and heard a lot of good things about them i was going to go with ss xxx's but i heard the surrounds aren't all that great and tend to require a recone more often than not Edited November 20, 2009 by deadbroke Quote Link to comment Share on other sites More sharing options...

deadbroke Posted November 21, 2009 Author Report Share Posted November 21, 2009 so after having researched around a little i finally found a relay for more than 200 amps. the pac 500 off sonic electronics. here is my plan now having listened to all your opinions on batteries i came up with a new idea tell me if it sounds good. i have my two 2150s on my dedicated system and a pc 1500 hooked up for my truck only running its own 300 amp alternator. my idea was to run the relay after the pc1500 to my buss bars allowing my amps to run off of all 3 of my batteries and 3 300 amp alternators. would this help eliminate my need for more batteries and by the way i am pretty sure i won't be playing my system at max for more than a minute or so. thoughts, opinions, ideas. thinking of ways around more batteries lol not lazy more like space saving. thanks fellas Quote Link to comment Share on other sites More sharing options...
brewer_brewer Posted November 21, 2009 Report Share Posted November 21, 2009 you would have a greater benefit of not isolating that 300 amp alt to just your car. it only takes about 80 amps to run most cars, so the other 220 or so would just be wasted just run all three alts together and connect the front battery to the rest of them.
