If you have a hard case between the tire and amplifier setup wouldn't that be fine? Or perhaps have an array of springs allowing the amplifier to "float" within the hard case set in the tire?
I like the way this looks because you can drop the whole system and the rubber protects.
Speaker, not amp but you made enough sense to get the point across. I think maybe, buy there's also the resonance chamber behind the speaker to consiter too.
Not as long as you think though. ;)
