OK this is a guess... So don't make me run if I'm wrong... I believe that the rear speaker wires from the stereo run into the gain amp, when off I believe that the signal is just bypassed to the rear, when on I believe that the signal is amplified... Again I could be dead wrong... I will say that the stock head unit, in the 88-91 SSE does have a decent amount of power... I have pioneers in the rear of mine ans it shakes the crapp out of them, makes the rear view shake... And thats without the gain amp...

So you think that the gain amp uses a speaker level input from the headunit? If this is true, it should be easy to tap into it. We would need to have all of the components together on a table to find out for sure how it works. Aren't there any engineers at GM who can explain this audio system so we don't have to guess?

That makes sense now. But then again, technically shoulnd't my gain still be working now if it'* just connected to the rear speaker lines from the head unit? Now I'm thinking future shop (canadian equivalent to best buy) totally got rid of it, which would explain the new speaker wires in there. I got to see what they did.

oh and Poke, keep those diagrams coming!

When the "technicians" at futureshop hooked up your system, you are lucky that they didnt blow everything. From this picture (thanks Poke) It looks like the gain amp is wired up with an 8 volt preout from the deck and a remote turn on wire. When they installed your deck they probably got confused and ran new wires. If your deck seemes to work properly then it should be safe to use the wires they put in.
