When I did this with the speaker wires going to the driver's door speaker, there was no click, so I have a wiring problem between the amp and the driver's door speaker. It has started raining again, so I'm going to call it a day. I've had that driver door opened a bunch to fix the micro switches, door latch and the lock assembly. There is a good change I forgot to hook that speaker back up the last time I was in there. Here's hoping!

Be careful what you test with a 9v battery.
Hook it to the wrong wire and you can damage the DME/ECU
The two things to test circuits with are a simple test light.
And A Digital Multi Meter
With a DMM you can test anything electrical on any car.
