SO as we all know, changing the rear speakers is next to impossible since they are dual voice coil and no one makes aftermarket dual voice coil speakers.

But lets be real here... I have a roadster, with the top down i dont need theater crisp audio. If i were to go to crutchfield and pick out some infinity or fosgate speakers that fit in the front and in the rear, what kind of bass loss are we talking here? COMPLETE LOSS or what?
