I have a 2006 mustang and am about to run a fusion 2500 amp and eventually an amp to power sone comps up front. What brand of alt is recommended? I've looked at a 220a powerbastards and a 250 At maniacelectricmotors. With this alt would I need a new battery besides a stock type? I was thinking a yellowtop since it fits in the tight area I have. I want to save but want good quality of course. Thanks
