bhorne,

I am in the process of finding a replacement for my 1991 SDL's FM/Tape (Becker, I guess - don't know what model - but, it looks good and sounds bad!)

After a lengthy discussion with experts at Crutchfield (Robert, ext 3281) I believe the following to be true:

- aftermarket systems put out different voltage that amps are expecting to get
- can get aftermarket system with two outputs for two amps (aftermarket required - in the cheapest $170 range each) and then use existing speakers (mine reportedly has ten separate hook ups)
- can get aftermarket system and run new wiring to aftermarket speakers (will do max of four - unless you go back to separate amps - and then you are back to the same solution as above).

Yours may not be the same as mine, though.
