Anyone have, or know anything about, a low level "hiss" on Shaker 500 system? It's audible even when the volume is all the way down and the power is on - in fact, the volume control does not do anything to the sound, it stays the same.I originally thought it was coming from my iPod connection but it's audible regardless of input selected.

You can't hear it with car running (obviously!).

 

that is just the noisy ford/jbl amps. They have never made any claims as to sound quality, or dependability, or features, or price.............

I wish I could get a mustang with NOTHING in it stereo wise....
