Buzz sound from dash PCB
I recently upgraded my sound system in my 69 Chevy PK by updating the orginal AM/FM radio to stereo and mounting a 10-disc CD changer in the g-box. I sounds great, but it seems that the plastic circuit board in back of my dash is resonating when I crank it up. Anyone have a fix for it?

Re: Buzz sound from dash PCB
A good set of headers and the right exhaust can clear that right up for you!
 What do you mean by resonating? Is it constantly vibrating, or does it only make noise when the bass thumps? You could try to take the dash apart to tighten things up? Or is it more of an electrical issue?

Re: Buzz sound from dash PCB
I've got some kind of vibration in my dash/ heater area too. Only does it occasionally on acceleration. Seems to be some sympathetic harmonic thing with the engine noise/vibration as I don't have a stereo yet. It's driving me nuts and so far I can't quite zero in where it's comming from. It NEVER does it when I have a hand up there to feel the vibration. At least you know where yours is comming from.... I feel your pain brother.
