Hey all! So, I'm troubleshooting the front door speaker not working and what started as a simple project relegated to the door speaker only...has turned into me essentially gutting the interior (I have a bunch of other interior projects to do too, so it was just a good time...headliner, CDL, etc.). Anyway. I've run through and inspected pretty much the entire run of wire using the wiring diagrams, tracing the wires from the speaker to the amp, and all looks good. The speaker itself is good, and I know this because I connected it to a door that works and the speaker played fine. Is there anything I should be looking at that I haven't?? Totally stumped.

 

fuse on the amp perhaps. I'm not entirely sure there is one, but most amps do.
