Help with one speaker not working
Hi. I purchased a 2015 RGS last year with the harley boom stage 2 kit installed. Today I noticed that I am only partially getting sound from the right side. I am getting sound from the tweeters but not the main speaker. I flipped the wiring harness connection in the fairing from the left to the right and the speaker fired up so I know the speaker and wire are ok. I am not sure what to test next. Does it seem like the amp is malfunctioning? Would it be possible to get sound to the tweeters but not the main speaker if the amp went bad? I'm assuming I can rule the head unit out since its getting sound to the tweeters.

Just to add onto this a little more to explain the boom amp. There is a wiring harness attached to the amp. From the harness, there are separate wires that go to a tweeter, a mid and the main speaker so 6 wires to each side of the bike. Is there any way the amp sends a different signal to the tweeter and mid versus what it sends to the main speaker? I'm starting to wonder if I could just splice into those lines to connect my main speaker again. I really have no audio experience so have no idea if that would be a horrible idea that would damage the amp. The main speaker has a ~12" wire that connects to the main wire harness so I have been able to eliminate that short wire and the speaker as the culprit. Is there any kind of test I could do at the amp itself where the wire harness connects to determine if it is even sending a signal? Open to any suggestions.

I've still been trying to research this. After doing some additional reading, I found that the boom stage 2 speakers are powered by 4 channels from the boom amp. 1 channel powers the woofer and 1 powers the tweeter/mid. For any of the audio guru's, is there any way that I can use a multimeter to test the pins on the amp where the wire harness connects? I can see the wires that run to the right woofer so I can tell which pins they are.

Think I'm taking to myself here but I'll add to this just in case anyone ever pulls this thread for reference. I was able to push the multimeter leads into the back of the wire harness. 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. Now to figure ito what to replace it with.

You are correct in the boom system uses a bi amp system meaning different channels powering the tweeters and woofers. That setup is exclusive to the hd system and there is no aftermarket amps or speakers that are compatible for it. So your only choice is replace the bad amp you have with another hd amp or take it all out (amps and speakers) and start from scratch using aftermarket amp and speakers.
