I'm resurrecting this thread because I installed the full BSW package about 1.5 years ago. There was some minor modifications for installing the little mid ranges in the doors if I remember right. everything else was a direct replacement. The kit came with a good amount of dynamat which I completely covered the speaker area of the front doors as this area really vibrates at certain frequencies.
When I first powered them up, I was very disappointed as the bass actually seemed no better or actually worse and the highs seemed overbearing. That being said, after a couple of weeks of really hammering them, they broke in pretty good. I'm now pretty happy with them. I can really get some good pounding bass out of the system. and by backing down the high end, it killed some of the shrillness.
The only problem is that the package shelf in the back vibrates like a Mo Fo at certain frequencies and it is really annoying.
Everybody knows that the rear speakers and the front door speakers are identical, right?
For those of you going to the meet, bring your favorite tunes and ask me to check them out. I have an AUX jack so, if you have an iPod, we can do that too.
