RE: BLown sub?
Amps only have a certain amount of voltage that they can use. This is called rail voltage. Well what happens when you play an amp safely and keep it in it's RMS voltage range is you get a nice wave form. When you try and push an amp too far it hits what's called it's ceiling the signal is no longer an AC waveform, instead the peaks of the wave are cut or "clipped" off. This produces a DC singal to the sub. When the sub gets a DC signal, it no longer moves in a smooth linear motion. It stops moving for that amount of time it's getting the DC signal. The linear motion of the sub and the air the cone makes moving back and forth through the voice coil is the subs primary method of cooling itself. And like I said, the amp could potentially be sending 4 times it's rated power to the sub. So when you send 600-800W through a speaker that can only dissipate 200W for any period of time under normal conditions, and it's cooling capabilities are cut even more from the DC signal.... you get a nice paperweight.
Now also keep in mind, your headunit can do the same exact thing. If your headunit clips, it's sending an already clipped signal to the amp. The amp then amplifies that clipped signal and sends it to the sub. Again possibly causing damage. So you can see how important it is to tune your system right.

RE: BLown sub?
what can i do to help clean it up? aftermarket head unit? i really want to keep the stocker though. an external crossover maybe? the thing is that the distortion is at low volume as well i have yet to turn ity even half way up because its so loud and bad. i tried different sources of music as well..cds radio and no luck. the door speakers play loud and clear though.
