Radio Wiring Question

[cptgonzo]

So I have installed most of my upgraded system, but I cannot find anywhere a wiring diagram of the underseat subwoofers. I have the technic harness, but seems like the Headunit is not outputting front right at all. Just trying to narrow down where a short or break is possible before replacing the entire unit (or summing the left front for mono =-( ). Please help me!!! I know two of the wires are inputs to the sub and the other two are outputs to the door speakers, but I cannot tell which one are which. It is the base system with 6 speakers and no amplifier, cannot find a wiring diagram online to save my life.

Here you go.

The front door speakers and the subwoofer are wired on the same channel. This means that they are wired in parallel on the same wire.

So theres 2 wires that come from the radio, that go to the subwoofer first, then these same wires come from the subwoofer and return to the door speakers.
