I just upgraded to a 220 amp alternator (never really noticed dimming at 130amp stock) but one day it just died. I have a kx2500.1 (2500watts rated) amp in the trunk pushing a kicker solo x 12 (pulling about 1250 max due to the impedance). I'm about to get another solo x to get the full 2500 watts plus maybe another 750 for door speakers. I've had some say get a cap or two and some say get a second battery set up. The messages have been so mixed that I am not sure what to do. I can't afford to burn out this $500 alternator. I searched some of the previous posts about the second batteries and caps. There was no clear concensus of if you have this many watts then you need this particular set up...
Can we set the record straight?
