solid connection to the battery? I had a problem similar to this and just had a bad connection.

if you physically push on your subs do you hear a scratching noise ?? ... if you do then it is highly posible that your voice coils are rubbing ... in that case be carefull running them ... you can have serius problems (blow amp).
