Need help trouble shooting audio
Hello. I posted in the audio section but am not getting much response over there. I have a 2015 RGS. When I purchased the bike, it had the stage 2 boom audio upgrade. My understanding of that system is that the amp operates in 4 channels. 1 channel per side sends a signal to the tweeter and mid range and 1 channel per side also sends power to the woofer. On the right side of the bike, I am getting sound from the tweeter/mid but not the woofer. Does anyone know if it's safe to at least say that the head unit is functioning properly and I likely have a bad channel on the amp that is not sending power to the woofer? I have tested the speaker and its fine so the problem seems to lie somewhere between the speaker and the amp. I just do not know a ton about audio troubleshooting so am not sure if theres anything I can test with a multimeter or something along those lines.

It's the 6.5 system. This boom stage 2 system was installed 3 years ago. This is a new problem where the woofer on the right side is not firing. Left side fires fine. I tested the speaker though and it's fine so I'm assuming the channel from the amp to the speaker is not sending a signal. I just do not know how to test that.

You basically want to switch connectors at each end and see if the issue is the wiring or the amp.

I would start by pulling the fairing and checking all connections. If the problem persists or nothing significant was found, try swapping the right woofer connector with the left and see if the problem follows. If it does, you most likely have a faulty channel. Doubtful the amp is still under warranty, so now may be a good time to pull the Boom stuff out and go a different route.

You could use a multi-meter and see if you have voltage on those pins with it on, it will be less than 3 volts AC. You can read it between the + and - of the output. But if you were able to swap the connections and the right sounded fine and the left got nothing, then most likely that channel took a dump. Looking at the schematics in the install sheet, you should be able to disconnect the amp from the right speaker and head unit and the plug the HU connector back into the speaker. This MAY or may not work as the flash that was installed for the amp to work turns off the internal amp in the HU.

Yes, use VAC for that. Might need 3 hands to do it, red to positive and black to ground or -. Start with the volume at 0 and work up, don't put the meter on there with it at full volume, as it may cause issues. Also, if they are female pins, you can wrap staples or paper clips around the tip of the leads to get them in. Again, just like jumper cables don't let them touch.

There was no way to test the pins directly on the amp because there's no power to it when I disconnect the wire harness. I was able to push the multimeter leads into the back of the wire harness however. With the volume half way up I was getting a reading of around 2 volts on the working side. When I switched to the plug wires for the other side I got a 0 so I'm pretty sure that confirms the channel went bad. Very frustrating. That amp had less than 10k miles on it and this weekend was my first chance to ride the bike since winter so it basically went bad sitting in the garage.
