Well, I'm a believer. Treating the doors took hours but the difference is amazing.

I got two rolls of b-quiet supreme (Saskatchewan product!) and used a full roll on the front doors; 1 layer on the outer door shell and 2 on the inner and the bass is amazing.

I tried to seal them completely but couldn't around the door locks, etc. But they are pretty close to being sealed.

I used the OEM plastic baffle on the drivers side, with a foam *baffle) and lots of non-hardening clay wedged in around the baffle and the door (with b-quiet under the baffle).

On the passengers side, I shattered the plastic baffle so made myself a replacement out of particle board (I plan on doing the same on the drivers side - that plastic baffle will shatter as well).

I would never need rear 6x9s and at this point I could live without a sub pretty happily for some time.

There is still a bit of a *bloom* in a certain frequency but it's not as bad as it was before. It's very apparent on female vocals - mid way through their range.

One question - how do you attach the drivers to MDF baffles?

I used some screw but they are not going to hold for long I would imagine.
