Was driving around today and noticed A very strange "Sub note"... Going to be hard to explain... The seats will vibrate and I can physically feel what appears to be the bass line from a bass song. However the radio is not on. It occurs every 4-6 seconds. Anyone have any idea? I would post a recording but it's not audible on video.

Currently removing all fuses that deal with the stereo to see if that resolves the issue.

Could be a harmonic from somewhere in the drive line. Does the frequency change with speed?

Did not notice it while I was driving. Only while stationary. Still drove perfectly normal.

Were you running your AC (or heat but I doubt that in Hawaii)?

FivePointToTheOh

Nope, all electronics in car were off

How would you recommend diagnosing the driveline issue if that is incase what is causing the issue?

I don't see how it could be a driveline issue if you are sitting still.... Unless its some type of harmonics from your exhaust. Or an earthquake!

I'm thinking its a harmonic drone or something from the exhaust.

The main issue is the vibration it's causing. I've had my exhaust installed for around 5 months now and never experienced this vibration. The best description I can give it is saying that it feels as though your listening to a techno/dubstep song every 6-10 seconds for roughly 1-2seconds. The issue did not happen today while driving. But I'm now watching it more closely.
