I have a '91 LS400 and both the front door speakers are not functioning. I removed both door panels and was shocked to see what they look like. Two sets of wires attach to the box. Usually I can use a meter to test resistance and continuity but I'm lost now. Does anyone have any advice on this issue or maybe you have a service manual that elaborates on this problem. The speakers themselves look sound, but before I decide to crack open the box and take a soldering iron to it maybe some has dealt with it and found an easier solution.

Thanks very much.

Peace.
