[200q20v] Help needed on non-Bose (Avant) radio replacement

There is an amp/crossover (booster per Bentley). It is located under the
rear seat, to the drivers side of the centerline. I'm no car audio expert,
but I did a fair amount of cursing and head scratching trying to put new
speakers and crossover in my Avant. My car already had a non stock Alpine
radio in it with the original speakers. In the course of my journey, I found
they had some kind of variable output device hooked up between the radio and
the rear 'booster'. I took that variable output device and the booster out
and hooked up the new speakers and crossover. I guess my advice is, if you
are keeping the stock booster, you may want to consult a pro car stereo shop
to hook up the radio to it.
