Sorry about redundant questions, but my searching only gets me conflicting information. The 4D-SEDAN, NON-BOSE stock 6d changer system has either 5.25" or 6.5" in the rear doors, which is it????? I can't believe they are that same as the fronts (as one post stated) except the rears have no tweeters, the fronts have 10 times the bass response. So I'm guessing the guy who said 5.25" was probably correct. Does anyone know for sure???

Whatever they are, they are going away, sound is really bad. Any suggestions for replacements are welcome, just need good aftermarket direct replacement to be powered by the stock head unit, have already added separate sub/amp.

Thanks!
