Always have issue with her but my latest - amp on the speaker, drivers door gave up. Where to find a stock replacement ?

Found the Bose center (through a member on this site) that sold me two new front speakers(stock) C/w amps.
Two new amps for the rear Bose tube base system and center speaker.
I installed all of them myself and found passengers amp did not work. Sent it back for a replacement. Meanwhile I found a local stereo guy (in Surrey BC) who can fix the amp electronics on the old units, could have saved me a bunch to got that route.
I am currently looking to locate the center speaker amp....where the hell is this thing????

First three months I had the car engine blew.... Seller dodged me and screwed me royally.
Tekam in Burnaby BC rebuilt the engine and installed new turbots as they were as the mechanic called it "cooked" I call it they ran the car hard and put her away wet... cost $9G's
