I've recently installed a 400W amp for my 4 interior speakers, a 200W amp for 2 tower speakers and a 500W amp for 2) 12" subs. I also have a heater installed. I believe the stock alternator in my 2003 21i is a 70amp. Can anybody give me some advice as to which exact alternator I should install? I went to Battery Shack, and it's too confusing, part numbers out the whazoo and way too many questions. I want the simplest, most reliable solution.
TIA,
John
