Radio Popping

Over the winter I installed a new Kenwood amp and receiver. Worked fine after the installation, happy, happy.
But now, after putting the bike away for the winter, the volume will not go above 18 without popping. The higher the volume I get nothing but popping. I can hear the volume fine below that, without interruption.

I have checked the wiring and all seems to be ok. I wondered about interference from something else but I thought that I would have had that from the beginning. I sent a note to Kenwood to help me troubleshoot. I may have to remove the amp and just hook up the power and speakers and see if that resolves things.

Anyone have thoughts on this?

I couldn't fix my brakes so I made the horn louder
Motor started to knock. Turned up the radio.

Yeah Try that "remove the amp and just hook up the power and speakers and see if that resolves things". An elimination process for sure but that's how it goes sometimes.

Was your bike kept dry all winter?

Last Saturday I planned on doing nothing all day, and by noon, I was half way done!

Yeah. Have it in the garage and have not ridden in the rain. Going to see what Kenwood has to say before I tackle taking the amp off. Looks like it is in my future though.

Sounds like a low voltage problem. Most amps have a safety circuit built in to kill the power to the final amplifiers in case of low voltage. You may be right at the threshold voltage. Hook up a voltmeter to the battery or the power leads to the amp and see if it drops when you increase the volume.

That makes a lot of sense. Even though the amp seemed to put out a cleaner sound, I can live without it. I'll test it this morning and if the voltage drops I'll pull it out. Put it in my truck. I'll post up with the results.

There is a power drain at the amp when the volume is turned up, and it recovers as the volume is dialed down. I'm going to take the amp out today and go from there.

I would love that. My free lunch has already eaten up about $350 of my lunch money. I talked with Kenwood today and they think my amp has a problem. Gave me a test to do by hooking up my cell phone to an RCA jack. If I still have the pop then it is the amp. If not, then it is the radio. Having to order the 3.5 to RCA wire and then we will see.

If I don't have problems, I'm not trying.
