upgradiing 200 TQW stereo

["Lawson, Dave" <dlawson@ball.com>]

I have a question about installing a head unit into my 1990 200 
TQWagon non-bose. I previously had the stock audi cassette/receiver, 
but removed it and gave to a friend. I have 3 heads sitting around 
which can be installed.

Option A - Denon 53something removable cassette deck, 4 speaker
level outs and rear pre-amp outs
Option B - Nakamichi TD300 cassette deck with single pre-amp out with 
external Nak pre-amp splitter/fader, needs four amplified channels
Option C - Sony XKR100 cassette deck, 4 preamp outs, needs four 
amplified channels

I have the crutchfield adapter harness' and some special signal box which
crutchfield said I needed to interface to the rear speakers in Audi cars.
I also have a 4-channel Alphasonic amp and 2 2-channel Proton amps
sitting on a shelf. I also have an old style Audi RF CD changer which I am 
planning on putting in. It works and the price was right. 

Is any particular setup easier to integrate into the Audi system using the
stock rear amp? Should the stock rear amp not be used? or removed? 
Where is it located in the wagon? Has anyone found a good place to 
mount amps in a wagon?

Looking for some helpful hints...
