circuit city does sell a 1200 watt amp, because i bought it from there partna. And i was going to by a capacitor very soon, and i dont wanna return it cause they gave me a sick deal on it already, and they didnt touch the door speakers so i dont think their liable for that problem. It only happened when i turned it up loud for the first few times, and then almost seemed to have stopped. Ill get some kind of better diagnosis and get back to you guys
