jeff i did a good deal of work today on the system. heres what i can tell you

I pulled out all the speaker/amp enclosures. Then i tested the power and groud of each of the 4 plugs. All 4 locations have good power and ground. I also checked the fuses assoicated with the radio (the fuse in teh auxillary box labeled RDO fuse 10amp, and the fuse in the top left of the main fuse block called CTSY fuse 15 amp. Both fuses were fine except the CTSY location had a 10amp fuse instead of a 15 amp like it should but it was still completing the circuit. I am going to change that tomorrow)
I plugged the head unit back in. The clock display shows. The radio turns on and the antenna goes up. I then precedded to plug back in all the enclosures and try to get sound. The front two speakers made no sound at all. The back two speakers made a humming noise that ocasionally randomly changed pitch. I also tried playing a cassette with no success. Turning up the volume control on the head made NO diference in sound at all. PLEASE HELP im out of ideas. What do i need to do next and also what size are the speakers in the car just out of curiosity.
