infamous360 Posted September 6, 2011 Report Share Posted September 6, 2011 (edited) my voltage is randomly dropping while driving. I usually play my system at about half volume. big 3 is done in 4 gauge.. I didn't have any 0 gauge at the time. I do plan on upgrading to 0 gauge alternator is stock the only battery I have is an optima yellow top under the hood my question is, should I get a bigger alternator or another battery? Ideally I would get 2 XS D3100s and a 325 amp singer alternator but money is an issue. System is in my sig Edited September 6, 2011 by infamous360 Quote AlphaDamp CLD Mat - Get more Sound Deadening with less Sound Deadener Link to comment Share on other sites More sharing options...

Low voltage doesn't blow amps. That's a myth. A router that does the sub holes makes rounded edges also? Link to comment Share on other sites More sharing options...
