I haven't taken a good enough look at the rear speaker wires, but I'm a little confused about something here. Is there a crossover? I know the stock speakers are dual voice coils and have tweeters right next to them. Is there a crossover? I see "Subwoofer Output," but I haven't been able to get to the amp wiring to see what'* up. It'* all encased in that awesome GM electrical tape. The OE amp is in my garage right now, but that probably won't help except that I could hook it up to 12V and see how it works.

Are the rear 6x9 speakers kept separate from the tweeters? How do the dual voice coils connect to the amp? I am going to take a wild guess and say that the sub out from the amp goes to all four speakers in the back via a crossover hookup.

One of the voice coils in the 6x9s are powered by the headunit. This coil is also wired in parallel with the tweeter which has a capacitor in line with it as a crossover to keep it from getting bass. The second 6x9 voice coil is powered by the GAIN amp and is crossed over to only provide bass. If you are asking because you want to upgrade the components, just omit the gain and go with an aftermarket head unit and 6x9s. Just make sure that you use the RADIO outputs and not the SUB outputs.

Thanks a lot for clarifying! I actually already have an aftermarket head unit with new amps and new speakers all around. That really helps sort out some questions about the amp, so thanks a lot! I hope to be able to make some great use of that amp soon.

Could someone with stock 92-95 SSEi speakers tell me the ohms of the two 6x9 voice coils please? That would be extremely helpful in determining my next step with the amp and some wire runs. Thanks!
