Have a RZ4-3000 amp BT Titans in front and kappas in the rear pods 62.11? Rear left speaker humms and buzzes. When I turn bike on. With or without running engine. If I crank the tunes I can still hear it but for the most part is drowned out. Any ideas what that might be? thanks

 

Need a little info on head unit, amp high or low level? Can be a rca issue, loc, line leveler if newer boom hu. Swap the speaker connection and see if the rear right does the same. Sounds like a input issue to me

 

Agree with Slye. Also might want to check the speaker itself. Last time I encountered that issue. it was the speaker.

 

Budda, swap the left and right rear speakers at the amp and see if the noise moves to the right rear speaker. if it does you know its from the amp back to the radio, if it doesn't then you know its from the amp to the speaker.

I have a feeling what you'll find is the RCA connector for the left rear input to the amp is likely rubbing a wire or ground point.

you should tape up any metallic point exposed on RCA connections.

 

Thanks will try the suggestions. Hope I have the time to get it done before the rally next week. Tanks again for the help. BTW HU is Kenwood X998.

 

I used electrical tape on all RCA cables. On all 8 ends. Seems to have corrected the issue. I had a issue about 4 weeks ago my 8 weeks. RPM noise. I bought some higher end RCA cables. Very short BTW. That fixed that problem. Then this happened. I thought RCA cables were the ****. I think it's fixed now but small issues are a pain. When there's limited time. Thanks for all the help and suggestions. Clear high quality sound is worth the effort!
