I have a Kenwood KMR 355U head unit powering 4 infinity speakers. System sounds great.

However, I have run into a problem. The head unit powers on, but I am not getting any sound out of the speakers. I had the power on a switch, so I took that off and ran it straight to the battery..didn't fix it.

I took off all of the speakers and tested them with the head unit individually, nothing.

At this point the only thing I can think of is it's a defective head unit. This set up was put in this season. It stopped working, then started working on another day, and now it will not come back.

Any thoughts? Open to ideas..

Thanks!

Welcome to iboats!:welcome:

Is the battery fully charged? Do you have to both the yellow and red wires?

I have a dual battery relay set up. I thought about the battery issue. Tried it on both batteries, same thing. That was my first thought.

I have the yellow and red wired together. I didn't want the stereo on the ignition. I put it on a switch under the dash. Tried going straight to the dash and eliminating the switch as well.
