It's like shaking and squeezing a ketchup bottle at the same time!



Except electrons aren't liquid...

And the doppler effect refers to sound waves compressing as they approach the listener (resulting in a higher frequency) and expanding as they move away from the listener (resulting in a lower frequency) - like when a car races by you as you face it... the pitch of the engine appears to become higher as it gets closer, then drop off as it passes you... I'm not sure how you related this to vibrations within a solid state amp, unless you feel the vibrations squeeze the traces and components, reducing electrical flow?!?

I'm sure we can all agree that shaking even a solid state amp isn't advisable, the only thing I'd worry about is shaking trim pots off calibration or over time loosening components, but a sheet of vulcanized truck bed liner stuck to the underside of the case isn't going to prevent any of that... maybe if you stuck a vulcan under there... highly illogical.
