AUX Static, Parking Sensors and Subwoofer rumble

AUX input is not going to be a fuse. It's more likely filth. Use a bit of alcohol on an electronics cleaning swab and wipe out your input jack.

Have a look at your sensors wiring. a damaged harness can make a mess of all sorts of signals

Either turn the base down or go through all your trim panels in the and find out what is loose.

Agreed - bad connection on the auxiliary input connector.

My subwoofer made a terrible noise - I removed the panel and found all of the mounting bolts to be loose and re-tightened them. Also check for nearby rattles in the side panels and tailgate with a particularly strong base track (or frequency generator app from your phone). I also had a loose fastener inside my upper tailgate trim - go that sorted too.

Once you've eliminated all of the exterior rattles, if the subwoofer still sounds bad you'll need a new speaker.

One more thought - if the subwoofer is bad and you have parking sensor problems, check for signs of water damage in both sides of the rear compartments and tire well.

Hope it helps.

Thanks!
I was able to fix the AUX-Static and Rumble. The parking sensors aren't done yet.
Thanks very much!
