Bruce Lau has brought out the first revision of the ebike audio amplifier (VeloAMP) originally released last fall. It has now been slimmed down to half the original enclosure thickness, while still maintaining the full 100 watts of stereo output power, 24-72V input voltage, a volume knob, speaker terminals, and an indicator LED. It looks slick, and delivers volumes. These units are in stock again for those wanting to play with loud and high quality sound systems on their ebikes.
