Lost sound on right side only

[Memphis]

Installed a new head unit a while back. Sound was just fine, all door speakers worked and the sub as well but a few weeks after I lost all sound on the right side. Anyone encounter this problem before and what the solution ended up being?

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

Do you have a separate amplifier for the speakers, or are you using the new head unit's built in amplifier to power the speakers?

Thanks for the warm welcome. Here's a pic of my truck. In regard to the amplifier, I am not too knowledgeable about car audio but what I can tell you is that I haven't added any amp so I'm guessing powered by the headunit? This is my headunit.

Check the connector plugs on the harness. Maybe a plug partially pulled out of a socket when pushing things back in place during install? Tension on the wire harness may have pulled more on one side of the connector plug, with some pins pulled further away than others. Full contact on some and partial on others... Could have been just barely making contact on install, then lost it hitting bumps on the road.

The fact that you lost the entire right side (front and back), with no external amplifier in the system, suggests that the problem is within your head unit.

Of course, check all of your connections, but for the entire right side to be out, there would have to be multiple issues within the connections, and that is unlikely.

I will give this a shot over the weekend! Hopefully it's something simple.

Did you ever figure out what was wrong? I just installed a pioneer unit wired through the Bose system and I have super low volume output on the passenger side, front and back.

Sorry for the late reply, I have not. I tried testing out the head unit but honestly I am not very handy with car audio so I am not sure I troubleshooted very well lol. I need to drop it off at a car audio shop to see what's going on.

Update, 2 years later lol. Turns out the factory amp crapped out. Ran a bypass and wired in an aftermarket amp/sub setup, all sound is back.

Better late than never, lol.
