Diamond Audio MICRO84U 660-Watt 4-Channel Amplifier for Harley



The all-new Micro8 line of amplifiers is essentially the same amplifier as the very popular Micro series amplifiers but with more power. The Micro84U is 275 Watts RMS per channel at 2 ohms instead of 150 watts like the Micro4v2. That's crazy power per channel, and it's all based on the proven Micro amplifier design. 


Fitment Notes: This amplifier is identical in size to the Micro4v2. This amplifier easily fits in the fairing of any Harley bagger '98 through '21. Our Bond-in amp racks for saddlebags work well with this amplifier
