I just got a 15" subwoofer for my birthday... I'm in love with bass so it rocks... But I need to get an amp and everything else to run it... And I'm not quite sure what I need. The sub is 500 watts RMS and 1000 peak. WHAT AMP SHOULD I GET?? Some people say I need over 1000, some people think I don't even need 500... and then there's 500x1, 300x4, 700x2, etc.. what does that mean?? I have 2 sony xplod 6x9's too, and an Alpine OR a Sony cd player for my car, the Alpine has subwoofer controls on it and my Sony doesnt, so i think I should use the Alpine, right? Oh yeah, and my sub is a Kicker Comp VR... I need to get an amp so I can get it all in my car soon!! Somebody who can help me please do so!
