Short version: RF woofer out, trying to figure out if I have an amp problem or audio control module problem. Test tips?
Looking for some ideas figuring out why my right front woofer is now soundless. Its been "going in and out" for months, but since now its been out for a little while, time to figure out what is going on.
1. I took the door skin off and did the test where you connect a battery. touching where at the connector, no sound. Taking the speaker out and bypassing the "stuff" between the connector and the speaker yielded results. Conclusion is that the "stuff" is a filter eliminating the sound generated by the battery.
2. So then I was off to the amplifier. I have the wiring diagram and understand that the wht/org and wht/vio wires on the amp represent a signal coming into the amp in the middle connector and leaving the amp on the lower connector. I thought i could just play some music and apply a voltage test to the corresponding wires- and yes while everything is connected I am applying a DC voltage test trying to get the probes down far enough in the backside of the amps connectors to touch the metal endpoints. Unfortunately I don't get results I feel strongly about. Sometimes zero volts, sometimes very little voltage, but if I switch to a different speaker (say left front woofer) I get the same results on a speaker I know is functioning properly.
What ways should I be testing for this? I was thinking maybe I should try again with some test tones so I could get more consistent with source input, but figured I would poll the audience.
