So there's absolutely no way to get the amps to send the EXACT same signals? Because it seems like if one amp was sending one voice coil one signal, and the other amp was sending the other voice coil another signal, that the sub would produce some sort of distortion or fight itself and not be as clean right? I don't understand how if the signal that is set on the 1st amp is just goin to the 2nd to be amplified and then sent to the sub's 2nd voice coil, where does it go out of wack? Am I missing something here? I'd love to go with 2 JL 1000's just cuz it would look amazing and the 1000 I have right now is treating me great, but if I'd have to sacrifice a good amount of sound quality with the dual setup, I'd definitly go with the 2500d.
