Okay. So I'm thinking what we have here is a good old fashion ground loop. Normally when your system is buzzing it's due to a ground loop somewhere in the system. Where do you have the amp grounded? What size power and ground wires do you have? What other electrical devices do you have grounded on the bike? The Jensen and SS amp normally work well together. Since you only hear the buzzing when the ignition is on. Something is interfering with your signal that's not on when the bike is in accessory mode. Normally the lights. Have you added any LED's or changed lights recently? Just giving you a few things the check out. You could always go purchase a cheap ground loop isolater and see if that helps. Tough to troubleshoot from 50,000 feet. I'm more of a hands on kind of guy. Lol! Any way report back on some the questions I asked and we'll go from there.

 

BINGO! I use a Kuryakyn Run/Turn/Brake controller. Unplugging it completely solved the buzzing problem. I would have never figured that out. Thank you!

I'm using 8 gauge power and ground wire. Grounded at the battery.

Is it possible to keep the Run/Turn/Brake controller and eliminate the buzzing?

 

8 gauge power and ground is excellent! Think ground in regard to the Run/Turn/Brake controller. Need to make sure it's grounded to the frame by any means necessary. You might have to run an additional ground wire or a thicker gauge wire. If all else fails I'd give kuryakyn a WTF call!

 

Success way to go Gannicus, love reading when someone sits miles away and takes the time and has the brains to solve a problem that he cannot nor needs not be in front of.

i don't know how i ever fixed anything before the Net this type of thing is happening in every category of my interest. But none of it would be possible with out the great people that are still out in the world.

 

Gannicus, you're the goods man. Pretty awesome that you solved that. Proof that if someone is patient and ask the right questions, someone here can solve any issue. Well done you guys.

 

Not sure how the kuryakyn is setup for wiring, but my bad dad rbt module only has a single power connection to battery, and remaining is plug and play up to wiring the lights. Only way to add any additional ground point is to tap into the plug and play harness and splice in a ground to run to battery. I would look into a better rbt module personally but you will have to open the wiring loom coming out of the rbt module you have to find the ground then splice and run another wire to battery. As far as op goes only option not mentioned I believe is to run a wire on the outer metal of the rca cable at head unit to ground and that will verify the ground loop. If no change it may be amp itself has a internal ground floating in the output stage somewhere.

 

I took the easy way out. The Run-Turn-Brake controller sold on ebay yesterday. Problem solved.
