John - I have a 2013 Road Glide Custom FLTRX. I have the following setup:
J&M ROKKER XT-P 500w 4-CH Class G Amp kit for FLTRX with Rear Speakers
ROKKER XX 7.25 Fairing Speaker kit
ROKKER XX Replacement 5X7 Speakers for Harley Saddlebag Lids
I installed the system per the instructions. Since I installed everything in June, my tunes were performing well with no issues. Harley flashed my HK head unit with Fader Controls, which I had favoring the rear speakers by 2 lines. During first week of July I rode the bike 2300 miles up to Montreal, Quebec City and back with tunes playing just about the entire way - no issues. I do not over drive the speakers.
2 weekends ago while on a ride, I noticed that the sound in the left front speaker started breaking up, or make severe skipping noises at only moderate playing volume. It started after riding for about an hour. Next day when I started the bike and played the music in the garage, there didn't seem to be any issues. When I went out to ride, it was the left rear speaker that was breaking up this time, again with just moderate volume level and only after riding for a 45 min-1 hr. Once it starts breaking up, it's there (breaking up, and not breaking up for brief periods) for good. When I get back to the garage and cut the engine, it seems like I can play the system as loud as I ever play it without breaking up. I checked for secure rear speaker wire adapter connections, and they're all secure. I checked battery connections, and they're good and tight too. This pattern of only breaking up on the road after riding for a while appears pretty consistent after a few more times experiencing it - always in the left rear speaker now.
The system is wired per the instructions and materials that were provided with all of the kits. I'm not sure if there is a heat problem that throws the left channel of the amp into a protective mode, or if for some reason the left channel is unstable under the load, which doesn't make sense because the amp is spec'ed and DSP configured to work well with the Rokker XX speakers ohm rating.
I suppose the next step is taking the outer fairing off, which I dread, to check the connections from the back of the head unit, and the amplifier. I thought you might recognize these symptoms and know what the issue is before I take that step. Can you help me get my system back to good playing form?
Thanks in advance...
