XxshadowdawgxX Posted January 19, 2013 Report Share Posted January 19, 2013 I am dipping down to 11v depending on how hard I'm banging my system. I'm wondering if adding another battery or upgrading the alternator is the answer. Quite frankly I don't think the H/O alternator is the answer because the Isolator does a good job of keep the front battery charged plenty its just not charging the back battery as fast as the Fi SP4 18'' is dropping the voltage. All opinions are wanted and if a H/O alternator is what you think I need then please voice it. Thank you everyone. Okay just a quick overview of my system... -1 18'' Fi Sp4 Fully Loaded -1 Kicker KX2500.1 (Custom Red/Black Paint Job) -1 Kicker ZX650.4 -1 Pioneer Headunit -4 Infinity Kappa 6.5" Door Speakers -1 Kinetik HC2400 Car Audio Battery -1 Yellow Top Battery -1 Concept Multi Battery Isolator/Regulator -5+ feet of 0 gauge wiring -1 300 AMP Fuse -1 8^3 custom box tuned to 30Hz.

Guest Posted January 19, 2013 Report Share Posted January 19, 2013 you NEED the biggest HO alt you can get. your stock alt hates your guts right now. do it before you fuck up that $800 amp you have. stop using isolators. you want all the battery power you can get. getting the power split is stupid. edit: also, i hope you have the big 3 done.

Integra_boomer Posted January 19, 2013 Report Share Posted January 19, 2013 Its like you got the penut butter and bread but no JELLY. Very good equiptment but missing one major thing that should an can easily be done first. Big three as these guys said. And a h/o alt will keep them batts charged. Nice stuff you got just missing a few pieces of the puzzle 1995 Integra GSR (DB8) Pioneer 3200-DVD 6.5 rockford fosgate 2-way fronts 6.5 rockford fosgate 3-way rear saz-3000D (2) 12" SA-12s Link to comment Share on other sites More sharing options...
