Overview
The HXM800.4D amplifier is one of our top go to amplifiers for powerful Harley sound systems. This amplifier is capable of driving extreme level systems. Due to the amplifier's 2 ohm stability this amplifier is well suited to situations with twin pairs of 4 ohm speakers. For example: 4 ohm speakers in the fairing and identical 4 ohm speakers in the lower fairings can be driven off of just two channels of the amplifier and the HXM800.4D will double its output to accommodate the demand leaving two channels available for rear speakers. Or even two pairs of rear speakers!
