200q Radio replacement done

[SOP8920@Siena.edu]

Hi Folks,
   I finished the replacement of my Delta head unit today. I installed a
Kenwood CD player/Receiver in it's place. 
   Tech notes (kinda):
(1) Production was split in two for the 1989 year. Although my car was a early
1989 (with a 1988 computer), it had the wiring harnesses for a late 1989. Go
figure. 

(2) If you order from Crutchfield, they may try to tell you that the Din
Chassis from the car will slide right out after you bend back the tabs. Mine
seemed to be one-piece across encompassing the cigarette lighter. IOW, they
didn't know what they were talking about this time. I've had good luck with
them before though.. and they are usually very helpful, but so-so this time. 

   (2a) The solution was, using various techniques , to gently
scrape the ridges that run inside the four corners of the plastic Din-chassis
out. The metal din-chassis that came with the new head-unit now will slide in
from the rear. It is a *very* tight fit however. Have patience. 

   (2b) Since my butane powered soldering iron (borrowed from lab) had a mini
blow-torch adapter.. I heated up the plastic first. This really didn't have a
massive effect but made the plastic ridges a little easier to scrape out. 
The smoke and small fires weren't amusing though. 

I'm not sure if this is a recommended route, but I tried heating my swiss army
blade up with the blowtorch and then using that to cut the ridges and it worked
well. Be careful with the blowtorch in the car!! ;)
   
(3) The Audi didn't have a switched 12v wire in the harness. I wired it to the
constant lead, as per recommendation, and now have a radio that always stays
mostly illuminated. I'm gonna have to run one from the fuse box. If anybody can
help here.. I'd really appreciate it. 

(4) I had to use a power-match to bring down the output of the receiver to
match up with the input of the audi-amp. It seems to work fine. The rear seems
to be receiving much more output now than before. It's almost hard to hear the
front speakers when the fader is balanced.

That's it.

P.S. Thanks for the help with selection and all that Jazz. The list was a great
help.. once again.
