No Bass in JBL Rear Subwoofer & Rear Door Speakers

[Chipmink]

I had the issue of no sound coming from the rear and the sub not working. As I was looking for a fuse and just decided to take out the Bluetooth speaker. All the speakers started working. I put the speaker back and it has been two days with no problems. Most random fix but I am not complaining.

WTH?! When you say “no sound from the rear and the sub not working”, are you saying that absolutely no sound was being produced by the rear doors soeakers, the rear lift gate speakers & the subwoofer?
Does the Bluetooth speaker even produce sound along with the other speakers in the vehicle? Mine doesn't. I've not used it yet but I've been thinking that the Bluetooth speaker is simply there as a novelty to take with you outside the vehicle to listen to. Is it simultaneously functioning along with the rest of the sound system somehow?
