Move stereo in 85AS

[Stonew98]

Hi All...my '85 AS has a car stereo in the shelf over the front sofa (just under the big control panel at the front of the RV).

I'd like to move it somewhere where you can't see it (I took out the slide up doors in my remodel and now have a shelf there.

Can anyone give me guidance on how to fish the wires to somewhere out of the way? Looks like the speaker wires run along the top of the trailer based on the wiring diagram, but maybe down the side...cant really tell.

Thanks!
