Why bother…the road noise and physical limitations make compressed digital formats like mp3 the choice of most noisy cars…there are so few really quiet enough and big enough to even accommodate the the wave length of some frequencies without lots of resonance problems. The only place it make sense, might be in a large travel trailer, and then only if stopped and plugged into a power outlet.
