I have a question on a possible cause for my sub woofer making an occasional thumping sound. I have an Infinity Basslink sub woofer connected to a Kenwood KDC-X696 head unit. I listen to music with a 32 GB Sandisk USB 3.0 Flash Drive and have my Samsung Galaxy S5 connected to the head unit via Bluetooth for phone calls. I have looked at both the troubleshooting section of the manual for my sub woofer and the fuse in the sub woofer and ruled out the problem being with the sub woofer itself. I have even readjusted the settings on the sub. The changes appeared to solve the thumping problem, but then I noticed earlier today an occasional thump. The grounding seems to be secure as well. I suspect that it may be the RCA cable between the sub woofer and head unit going bad, but I have one question about another possible cause. When I am listening to my music off of my USB stick, my phone is connected to the head unit via Bluetooth. When I make or get a phone call, my head unit switches automatically over to bluetooth mode. I am aware that a USB 3.0 device can cause interference with Bluetooth connections, but can a Bluetooth signal also interfere with a USB 3.0 device? If so, could this be the cause for the sub woofer thumping noise. I am not picking up any thumping on my car speakers. Thanks in advance.
