boostaroo or boostaroo revolution?
I play my mp3 player through my car stereo using a hard wired FM modulator and the sound volume is kinda low, even I set the volume on the player to 80-90% and really turn up the car stereo. I picked up a Radio Shack brand boostaroo headphone amplifier and it helps, but having an even bigger amp would probably be better. Does anyone have a boostaroo revolution or have experience using it with their car stereo? Is the revolution noticeably louder than the original and worth the extra money?
