After reading in here about how much better 6.5's would sound in the doors (and how they were even better than 6x9's because they were round) I finally built the template, ordered some speakers and installed the first one today.
Wow... am I diappointed. The new speaker doesn't sound any better than the Pioneer (in the stock door size) I am replacing.
I had put the Pioneers in a few years ago, and was disppointed with them, because with the small size you can only improve to certain point. But since they were the stock size and I wouldnt have cut, or build anything I thought Id give them a try. Yes, they were better, but not what I had hoped.
Fast forward to today... I expected a big improvement but saw None. In a blind taste (sound) test, switching balance control between left and right, there was no diff between new speaker on drivers side and old speaker on passengers side.
What gives? Shouldn't I at least had some more bass from the larger speaker, if nothing else??
The new speaker doesn't sound bad, its just not any better. The rear speakers still over power the front, and you must compensate with the faders.
