If you are looking for a top-level plug & play two speaker with amplifier solution, with expansion ability for more speakers, look no further! This is as beautiful as it gets. This True plug-and-play amplifier/DSP package includes an unprecedented level of pre-configured equipment. We have included a Techno Research radio flash module with this kit. Now you will be able to flash your bike for any configuration you want any time you want! The flash module also will enable Apple CarPlay for free without the need for any special parts. 

Magic Compression Horns

Diamond MO75T Horns

The Diamond Audio M075T is a dual-stage horn design with a much smoother sound and the full format diaphragm is large and robust. The magnet is in front of the diaphragm, and the voice coil is on the front side of the diaphragm, Which makes for far shallower mounting requirements.

Bold Pro Audio Mid Woofers

Diamond Audio MSPRO65

The Diamond Audio MSPRO65 6.5" woofers have a better punch and aggressive sound due to the use of convex cone geometry that increases cone rigidity under load while keeping the moving mass down. Lower moving mass = more output and rapid response for every watt of input.

Steel Speaker Grills with Horns Mounted

Street Glide Speaker Grills with Horns

We stamp and mount the MO75T horns for you. Black coated stainless steel fasteners are used, and a CNC machined HDPE backplate so that the speaker grills match the integrity of the rest of the bike.

12db Crossovers Add a Lot to Performance and Reliability

Diamond Audio Crossovers

The crossovers included in this kit are 12db crossovers with a much higher power handling and a much more stable output at all volume levels.

Musway DSP 4-channel amplifier

Musway M4+ amplifier for Harley Davidson

The Musway DSP is a true plug-and-play amplifier/DSP package that includes an unprecedented level of pre-configured equipment. We have included a Techno Research radio flash module with this kit. Now you will be able to flash your bike for any configuration you want any time you want! The flash module also will enable Apple CarPlay for free without the need for any special parts. The module will be VIN locked to your bike. 

 The M4+ is a lot more than a 4 channel amplifier. It is the perfect centerpiece to build a large-scale system around. With 4 channels of 6 volt RCA output in addition to the internal four amplified channels, you can go wild with multi amplifier systems. 

  • Intelligent high level input with EPS (Error Protection System)
  • Soft clipping in 2 Ω operation
  • Signal-to-noise ratio ≥90dB, frequency response 15 Hz - 22 kHz (-3dB)
  • Total harmonic distortion ≤0.1% (1 kHz, 4Ω, 90% power)
  • Separately adjustable input sensitivity (channels 1-6, AUX), clipping LED
  • Dual 32bit, 330 MIPS DSP technology controllable via PC software or APP
  • External Bluetooth® USB dongle ( BTS & BTA ) for audio streaming & app control (optional)

Built-In Dual 32 Bit DSP

Musway DSP Software Screenshot

We are in love with the Musway sound processor software. It is beautifully laid out and easy to use. Musway did a fantastic job with including all of the right bells and whistles but still keeping the interface and learning curve simple. The DSP can be accessed by connecting the included USB cable to your PC or by using the optional Bluetooth adapter (available late September) to connect to your smartphone (Android or Apple). 

Factory Harley T Radio Interface & Speaker T Harness for Horns Included!

Harley Radio T Harness for Musway Amplifier

Plug-and-play connections are included with this amplifier. This harness eliminates a ridiculous number of wire-to-wire connections (25!) in the fairing, making this the most complete plug-and-play Harley kit we have ever produced. 

Premium 8 Gauge Power Harness

Harley Amplifier Power Harness

The included power harness is 100% OFC (oxygen-free copper). The ANL fuse holder is waterproof and install-friendly. The power cables have been pre-terminated, heat shrunk, and loomed for you. Comes with a mounting pad making for a beautiful installation in the fairing every time.

Neoprene Speaker Gasket

It wouldn't make any sense to install the best speakers without properly sealing them into the speaker pods. So we include a unique but straightforward gasket that we have manufactured just for speakers in Harley Davidson applications. The adhesive and the neoprene rubber maintain integrity for years in extreme temperatures.
