Okay i own a raa2400 mb quart amp. It puts out roughly 800 watts bridged. However i am only using 200 times 2 into 4 ohms. I have it hooked up to two alpine type e's. Ppl on here said that 200 watts each would work perfect for these crap subs. But, my amp is clipping big time even when it isnt that loud. Is it my amplifier? or alternat or battery? I have a stock alternator and stock battery right now.
