Right now I have a M3 which has amazing sound, and was interested in getting a TSX. I was wondering if the acura audio system has an option so it increases the volume on its own when your car goes faster (vehicle-speed-sensitive equalization)... (i.e. on the highway)

 

I'm a pretty sure that it does not have such a feature. But, don't despair! A handy dandy quick-action volume control is located on the steering wheel.

 

I'm absolutely positively sure the TSX does not have that feature.

 

And I'm absolutely certain that MP3 players don't have "amazing" sound. But it's a good car...

 

Not possible... unless you design your own circuit
