Well, after much headaches and wallet draining, I have resolved my issue with my Bose system.
I have a 97 SSEi with the Factory Bose system, and AC Delco Casette radio with no EQ.
I had terrible distortion on the rear speakers (both) and so the logical thing there was either the amp of the radio unit.
Anyway, it was neither. I just bought a pair of cheap Jenson 6x9 speakers, 4ohm 60W RMS/180W peak and magically my system rocks again. Now yes, I know these arent the best speakers but they sound about 1000% better than the old Bose ones.
The old bose speakers sucked. They looked physically ok, but when I touched the cones, they crackled like brittle paper.
They were the dual cone type with 4 wires going to it. But from the Bose amp, there is only 2 wires, and then there is a connector that splits it up into 4 wires.
So now I have deep bass and the best part, was that they pit perfectly under the factory grill, and I was still able to hook up the factory bose tweeter thats mounted in the grill. So I have the 3 way 6x9 and an additional Bose Tweeter.
Sounds great !!
I will be selling my Used ACDelco radio soon, it works fine and looks great. I will also be selling my Bose 4 channel amp which also works great. If anyone is interested, let me know.
I guess the moral to this saga is: If you are broke and just want some half decent sound, dont listen to everyone telling you to rip out your Bose system. And don't bother replacing the Bose Amp or Delco Radio unit, they are usually just fine. Just replace the speakers with aftermarket ones and you will be happy. Definately replace the rear ones, thats a must do. The front arent as critical.
