Memphis MXAHDPRO4 4-Speaker 6.5" Harley Audio Kit

The Memphis MXAHDPRO4 is a complete four-speaker audio upgrade package for compatible Harley-Davidson Street Glide, Road Glide, and Tour-Pak speaker locations. It combines four direct-fit 6.5-inch speakers, a compact four-channel amplifier, vehicle-specific amplifier mounting hardware, and plug-and-play wiring. The system is intended for riders who want to upgrade both front and rear speaker locations while retaining the factory radio.

Two pairs of MXA62HD speakers provide the front and rear channels, with each speaker rated for 75 watts RMS and 150 watts peak. Their 93 dB sensitivity and neodymium magnet motor support efficient output in an open motorcycle environment. A low-profile film dome tweeter and integrated waveguide are used to provide high-frequency detail and improved midrange projection.

The included MXA300.4 amplifier supplies 65 watts RMS per channel at 4 ohms or 75 watts RMS per channel at 2 ohms. Its full-range Class D design, high- and low-level inputs, and selectable two- or four-channel input mode provide flexibility for the factory-radio integration used by this kit. The amplifier uses a sealed, IP66 water-resistant chassis and connectors suited to powersports installation.

MXA62HD speakers use carbon-fiber-reinforced polypropylene cones, Santoprene surrounds, Santoprene front spiders, and high-temperature glass-reinforced polymer frames. These material choices are intended to support outdoor motorcycle use while maintaining a direct-fit installation profile. Each speaker pair includes grille options for Road Glide, Street Glide, and rear Tour-Pak applications.

The MXAHD14KIT mounting and wiring package creates an amplifier mounting location in the factory fairing area and connects to the factory Harley-Davidson radio. Its harness is designed to flatten the factory EQ before the amplifier, so a radio flash is not required. This makes the MXAHDPRO4 a coordinated upgrade path for compatible motorcycles needing amplified front and rear 6.5-inch speaker coverage.

Design & Installation

The MXAHDPRO4 combines direct-fit speakers with a compact amplifier package designed around Harley-Davidson fairing and Tour-Pak locations. The speakers use carbon-fiber-reinforced polypropylene cones, Santoprene suspension components, neodymium magnets, and glass-reinforced polymer frames. The amplifier uses a sealed chassis with stainless-steel and aluminum hardware.

This kit is specified for 2014-and-newer Street Glide and 2015-and-newer Road Glide motorcycles, including compatible Tour-Pak speaker locations. Installation involves replacing the factory speakers and grilles, mounting the amplifier with the supplied brackets and hardware, connecting the plug-and-play harness, and routing amplifier power and ground to the battery. Memphis recommends installation by an authorized dealer, especially when confirming vehicle-specific fitment and wiring.
