I just installed Pioneer FH-P800BT on our 2001 saab 9-5. Everything works find now, except that there is a very loud pop noise from the speaker everytime when on turn off the volume (from 1 to 0), mute, change the source from radio to CD, or turn off the car.
Is it typical turn off thump? Does the method on Crutchfield.com in the following link works?
