I'm preparing an '89 240 wagon for my daughter. It has the plain vanilla am/fm casette radio. It has front speakers only. I purchased an amp specific for the radio (volvo, of course), and a couple of speakers for the rear.

I understand that the amp fits behind the little cubby hole where the radio used to fit on the older 240's.. by the shifter. Fine. I'm hope I'll find the plug that goes into the amp somewhere. My question is about the stock wiring. Is there any prewired wires for rear speakers on this model? It sure would be easier if I knew if they were there or not. I could find out what the color code is and also the location of the wires.

I've had many a Volvo in my time, but this is the first wagon where I am looking for rear speaker wires.

If all else fails, I'm planning to keep it simple and run wires to the rear door panels. I've searched around, and I know that options on speaker placement for the wagon are limited.

Anyway, any advice would be appreciated!
Thanks.
