Re: Poor Boys Sound Control..
Rainwater runs into the doors around the gaskets on the windows so if you have sealed up the drains in the bottom of your doors you will have a lot of problems in the future. Those problems will include humidity that will damage your speakers and make the windows hard to roll up and down as well as just generally promoting rust.
If you didn't seal those holes then no problem. Although, I'm not sure how good your midbass response will be by eliminating most of the cabinet the speakers are in.
I'd really like to see some pictures if you have them.
