Hey guys, 20 year old newbie here. Sold my Cobalt SS and got my 05 coupe with 48,200 miles for a great price in my opinion. QUESTIONS: What kind of amp do i need to power the 2 speakers, 2 tweeters, 2 subs in the stock location, and headunit. These are all AFTERMARKET products that I bought. I just need to know the KIND of amp I need. Mono, 4/3, etc. and how many watts. Thanks guys I really appreciate any help I can get!
