Subwoofer Troubleshooting

Recommended Posts

I've got a sub box that doesn't work and I was hoping to use a voltmeter to identify the issue.


I'm trying to configure my parameters and unit of measurements to adequately troubleshoot.


I plan to check resistance and continuity at the box level.

What parameter should I check at the speaker outputs and wires?

What parameter should I check at the RCA's cables, inputs and outputs?


I plan to check my deck configurations, wiring etc tonight.


FYI, My Amp turns on and all status lights are OK.


Any assistance is appreciated.


Thanks in Advance.
