chrishova Posted July 12, 2012 Report Share Posted July 12, 2012 Hey ya'll! I finally got my system in, 4 runs of 0ga., 2 pos., and 2 neg., still got grounds everywhere, the big 3, an Iraggi 300a alt., a yellowtop under the hood, and a XS 3100 and a 3400 in the back. I got a voltmeter hooked up to the amp power inputs. I have a SMD D.7 on a SAZ3500D and it will down to 12v . I was wondering if I should spend my money on dual alt setup, Iraggi said he can do one for my Grand Prix, or another XS3100 and a 3400 for the front?!?! Either will be about the same amount of money, what will be best?!?!? Thank ya'll!! Quote Pontiac Grand Prix GT400a Mean Machine alt.

chrishova Posted July 13, 2012 Author Report Share Posted July 13, 2012 I also have an Epic 160, and I did wire each "side" of the amp to each coil so I should be @ .35 ohm Quote Pontiac Grand Prix GT400a Mean Machine alt.

hdorre Posted July 13, 2012 Report Share Posted July 13, 2012 First thing I would do is clamp your current alt. Does it output at least its rating? I have heard a TON of stories...

SnowDrifter Posted July 13, 2012 Report Share Posted July 13, 2012 (edited) I vote another alt. If you are dropping that low, more batteries will help, but more alt will help more because you are dipping into battery voltage IMHO. I have a crescendo 3500 at .5 ohms, stock battery, and can hold 15v at the amp full tilt Edit: let me clarify. In every single setup I have seen, more alternator does better than more battery. Bigger/more alternators will be more effective in charging more batteries. They will charge faster and strain less while doing so. Imagine a pool with a hose going in and a hose going out. If your 'pool' is draining, wouldn't it make more sense to increase the flow of 'water' going in so it doesn't drain vs getting a bigger pool?

Tim Lam Posted July 13, 2012 Report Share Posted July 13, 2012 if room is not a concern, i would just battery bank it. since you already have the iraggi alt, i would add a second alt if you still got voltage drops after the battery bank. just my $.02 Quote Link to comment Share on other sites More sharing options...
Tim Lam Posted July 13, 2012 Report Share Posted July 13, 2012 LOVE the port btw, where did you get it? and get it colored? Quote Link to comment Share on other sites More sharing options...
Miguels Posted July 13, 2012 Report Share Posted July 13, 2012 is that alt even doing what its rated? i only have 2 kinetik 2400 and i drop to 13.8 Quote 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...
matt402 Posted July 13, 2012 Report Share Posted July 13, 2012 More battery reserve. ^this. batts > alts. id rather run a larger amp @ 1.4 instead of trying to overwork ur amp @ .35, u have more thd & current draw. Quote Link to comment Share on other sites More sharing options...
chrishova Posted July 13, 2012 Author Report Share Posted July 13, 2012 LOVE the port btw, where did you get it? and get it colored? Thank ya'll for the help! I got the port from Lowes!
