Stab in the dark here.

I have done two searches of my wires so far to try to figure it out. Don't know if anyone else has/had this issue and may help alleviate some things it can't be/shouldn't be looked at.

Radio speakers become statically and slight cut ins and out when warm.

It doesn't do it on bumpy roads, it seems to be a temperature issue.

I mean very warm, 80+ degrees outside and then it starts acting up.

Doesn't matter if it is radio, CD, or aux plugged in MP3 player.

Any ides? I am wondering if it is not a voltage issue.

Stock 2004 U.C. radio with 8 ohm Alpine speakers.

I have tried shaking the radio removed from support brakcets, nope.

Shaking wires and moving them around, notta.

unplugging and replugging wires back in. Nope.

Breaking radio open twice and checking all boards for loose connections or soldier points, visually checking components. Nope (I used to be a Certified Micro Solder Tech)

Anything I might have missed?

 

I didn't have your problem but something close to it. Turned out to be my power wire to the amp at the battery terminal. Had a broken connection there that cut everything in and out. Just a thought.

 

I will have to check that out. Very plausible.

 

Well, during this last 13+ day trip through cold foggy weather and very hot arid weather, i noticed that the speakers act up when it is 80+ degrees outside and doesn't matter what speed as long as the engine is engaged to the tire and bumpy roads makes it worse. Interesting thing is when I pull in the clutch, the radio normalizes out and sounds awesome. Let the clutch out and immediately it cuts in and out from mono to stereo.

 

I forgot all about this issue until yesterday riding home. The temps have been 70 and lower and no problems with radio/speakers. Rode almost all winter with no issues. Yesterday it hit above 80 degrees and the annoying radio issue is back. I had my bike sitting in the sun all day and when I started it up to ride it home, within 20 seconds it acted up. So it can't (shouldn't) be a hot alternator issue. If I pull in the clutch, it stops cutting out but the moment I engage the clutch, it cuts in and out and really really annoying.

 

I had the same issue with my stock radio sound head unit on my 01. I finally decided it was the head unit overheating, and "solved" it temporarily by installing an amp. It took the load off the radio enough that it didn't overheat and cut out.

I am currently shopping aftermarket head units for a more permanent solution.

 

hey bud.. have you checked voltages across the regulator and stator? With the clutch statement, leads me to believe it's one or the other if not both. I'd certainly check that before you wind up parked on the side of the road. Check the connector between the two, it may simply be dirty or corroded.

 

I will have to check that out. Thanks!

 

Also check all of your ground connections. The grounds are often overlooked and can cause some crazy things to happen as well.
