Biohazard
Just a little.
Today, I yanked the radio out along with the speaker I had previously installed in the dash. I have much to do up under the dash I decided to get some significant obstacles out of my way, the most significant being the radio. It's HUGE.
Anyway, starting with the speaker: I pulled the assembly out and separated the speaker from the mounting frame. Having arrived at the conclusion that I'll not be wanting to use that speaker in any actual audio capacity, I decided to make it's removal a permanent move. The speaker frame was covered with a piece of that thick shelf liner (the stuff I've been making body gaskets out of) drawn tightly over the top and glued in place. This will act as a sort of sound deadening blanket to reduce the amount of noise sneaking out from behind the dash and reflecting off the windshield directly into the occupants' faces. Reinstalled that.
While I rendered the radio useless some time ago, I wanted to keep it installed for appearances' sake. You'll know from several pages back that I gutted the electronics out of mine partly because I couldn't effectively sanitize the circuit board and to reduce unnecessary mass. But since the whole thing is like having a lunch box stuffed behind the dash frame and it makes doing work up in there nearly impossible, I was seriously considering trashing it altogether.
What I did do instead was eliminate the bulky radio chassis which was, by this time, little more than a partly empty box. Since all of the tuning buttons and dial are supported on the face frame, the chassis box was non-essential.
