caps are a WASTE of $$$!!! if your system is big enough(draws more then 100amps of current) a xtra bat will help but put strain on your alt. iv had an xtra red top(in trunk) on my factory alt for 5+ years with no light dimming when its cranked up, amp(s) are mmats dhcx2200.1's.. few years ago ive only been using 1 amp.. just this past summer my alt started goin out as my head lights and dome lights were startn to dim with the bass so i put an HO alt in. you should get an high output alt b4 getn caps!!!
