Rockbrook Posted January 25, 2011 Report Share Posted January 25, 2011 Most will say Big3,and for sure a bigger batt up front. See how much you drop, then maybe another batt but I doubt all that Quote Link to comment Share on other sites More sharing options...

dmanson Posted January 25, 2011 Report Share Posted January 25, 2011 Definitely the big 3 and upgrade that battery. If that fails then a new alt will do it.

skittlesRgood Posted January 25, 2011 Report Share Posted January 25, 2011 what is your voltage dropping to? what are the subs wired to? .5ohm, 1ohm, etc. Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

For 1500 watts I think the big three, a new battery (and maybe one in the back) will be sufficient.

Rockbrook Posted January 25, 2011 Report Share Posted January 25, 2011 Hell, when I had my JL Audio 500/1 my lights were dimming like crazy, but with the amp I'm running now wired to 2ohms my lights barely dim. And that's all on stock electrical...some amps just are a little more power hungrier.. Quote Link to comment Share on other sites More sharing options...
BURRack_Obama Posted January 26, 2011 Author Report Share Posted January 26, 2011 it is wired to 1ohm. it drops to like 9-10v at idle. and drops to 12 when driving city.(atleast what it says on stock voltage meter) Quote DD 9515 Rockford 1500-1 Pioneer 4200UB Knu 1/0 PSN = iHEART_daCLIT Link to comment Share on other sites More sharing options...
