Stereo/DVD WIRING

Your profile states a 2021 model. MOST newer(last 10 years) Trailers that have 3 sets of speakers, the Stereo itself has "A" "B" "C" speaker control and the Balance will operate on all 3 sets. Some of these Stereo's it is difficult to figure out HOW to engage the 3 speaker switches. BUT, If doing the balance kills 1 set, then it is probably miswired. It is common for the factory installers to miswire the speaker leads. I would take it b ack to the dealer and have THEM fix the wiring problem. POST the Brand and Model of the Stereo for us to give you more help. Doug

Just be sure to trace the wires from the speakers back to the stereo the best you can before snipping and replacing any of them. In my previous RV, the speaker wires at the speakers were Green/Gray and Green/White. At the stereo, they were Purple/Gray and Purple/White. Somewhere in the spaghetti mess of wires they were tapped into and switched to a different wire color. Also, RV stereo systems use a common ground and that could be anywhere within the RV so be aware of that.

Yeah, that is not stereo. I would expect a system with 3 sets of speakers to have a menu or switch to select which speakers to use. I had an old system that died long ago with 5.1 surround speakers in the living room (A speakers) and two bedroom speakers (B speakers). With the system menu I could select A, B, or both.

Messed up stereo wiring, and other screw ups are kind of the norm. My previous FW stereo speakers were wired wrong. It was obvious, after pulling the unit out, looking at the wires, and connections, which were clearly marked, easily fixed, and worked great after I made the proper connects.

Also the fridge door opened the wrong way, but easily fixed, and the city water entrance line was plumed into the hot water line.
