One of the front speakers will cut out when listening on AUX
 

So one of the two front speakers will cut out occasionally while playing music through the auxiliary port (headphone jack). I.e. if I change the "Balance" setting to "L5" when the left speaker isn't playing or "R5" when the isn't playing I can't hear anything. They have yet to both cut out at the same time. It used to only be the right speaker but the left one has done it a couple time too.

Strangely enough pressing the RPT button will fix it, sometimes... Pressing that button has also made the sound cut out entirely once. I thought the repeat button only worked on CDs.

Switching to AM-FM while this is happening still works, but when I switch back to AUX I still won't hear one of the speakers.

I thought it was maybe my phone, but it happened with my girlfriend's phone too. I even bought a new cable.

Any ideas?

This is the Bose system, no nav.

TLDR: Left or Right speaker will cut out on AUX only. Tried new cable. Tried other phone. RPT button sometimes fixes it

Dealershit issue

Could be some dust inside of the outlet. Try blowing it out with some compressed air if you have any. Also make sure the plug you're using is clean. You can wipe it down with some rubbing alcohol.

The jack probably needs to be cleaned or replaced.

Sure sounds like you have it narrowed down to the input jack itself. The compressed air method will definitely be an option to consider, or even a VERY light spritz with electrical contact cleaner if the air doesn't do the trick.

Edit : noticed you already replaced a cable. Definitely sounds like the jack itself.

Line or jack issue..

Thanks everyone. Looks like I'll try the compressed air & electrical contact cleaner. Otherwise I guess I'll have to take it in.

Be very stingy with the contact cleaner - many of them will react with plastics.

i use WD40 on a paper towel to wipe the jack and insert, turn a few times. usually works.

i do this on my music gear to from time to time when i have scratchy XLR's or TRS.
