Remove radio - add speakers
We have 2015 Thor Miramar. The two speakers in the driver cabin are inadequate for my hearing pleasure. We listen to books on audio, and I have to turn the radio up to "window rattling" to hear anything. I would like to put some additional speakers on the dashboard. I looked on YouTube for some directions to remove the radio and or dashboard to run some additional wires, but I didn't find any help. I would appreciate any assistance you can provide.
