The Best Sound Quality

Step into the top level of pro audio Road Glide speakers. This kit includes everything that you will need to add Diamond Audio M075T horns and MSPRO65 mid-woofers to your 2015+ Road Glide. This is a whole new level of loudness that simply has not been possible up until now.

Easy Installation

We include several parts in this kit that make installation a snap. Included are quick disconnect harnesses for each of the horns and crossovers. The included speaker grills snap right in place of the original factory grills. Each horn comes with a CNC machined HDPE backplate. All fasteners are stainless steel. The woofers are plug-and-play with the factory Harley speaker wiring, and many more installation goodies!

IP65 Marine Grade Speakers

These speakers are designed to take all of the weather that you can throw at them. They are treated for extreme UV exposure, extreme swings in temperature, high vibration, and water.

Competition Level Parts All-Around

There are no performance bottlenecks in this entire kit. Every part is the latest and greatest. The Helix amplifier has the most advanced DSP on the planet, The speakers come with custom grill-mounted horns, and every component comes with the best possible connection and wire harness solution possible. 

The Magic Compression Horns

The Diamond Audio M075T is a dual-stage horn design that has a much smoother sound than what is normally possible. The full format diaphragm is large and robust which allows for extreme level output volumes. The magnet in these horns is actually in front of the diaphragm and the voice coil is on the front side of the diaphragm which is genius and allows for a much more compact horn design that easily fits in front of the midrange.

Bold Pro Audio Mid Woofers

The Diamond Audio MSPRO65 6.5" woofers are a big improvement on all other pro audio type mid-woofers on the market. These woofers have a better bottom-end response. Other popular pro audio woofers sound notoriously thin on the bottom end. Diamond Audio uses a convex cone geometry that increases cone rigidity under load while keeping the moving mass down. This makes the speaker louder and better sounding.

Installation Note: The factory speaker pods in the fairing require a light modification for magnet clearance. Simply heat the plastic speaker pod with a heat gun around the area where the magnet touches and screw the speaker in place. The plastic will then conform to shape allowing the speaker to fit perfectly. Note: The improved bottom end response of these woofers is superior to other 6.5 inch woofers on the market but should not be confused with the bass response of larger woofers like subwoofers or 6x9 lid speakers. 

Steel Speaker Grills with Horns Mounted

We stamp and mount the M075T 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

Most of the horns on the market come with 6db caps for crossovers. Those types of crossovers have a lot of problems though. The sound of a horn using just a cap changes dramatically with volume, making it impossible to tune your system to sound equally as good at high volume as lower volumes. The crossovers included in this kit though are 12db crossovers with a much higher power handling and a much more stable output at all volume levels.

Helix M FOUR DSP 4-Channel Amplifier with Integrated 10-Channel DSP

The Brand New Helix M FOUR DSP is a powerful 4-channel amplifier with a fully-integrated digital sound processor manufactured in Germany that brings a continuous output of 135 Watts per channel, both at 4 Ohms and 2 Ohms. This game-changing control center is cool, compact, extremely practical, and up for any challenge in your Harley system.

Perfect for integration with factory Harley radios, the M Four amplifier/DSP has a number of features that make it totally different than anything else ever made.

Factory Harley Radio Interface for Front Signal Included

No need to buy a separate radio connection harness. Plug-and-play connections are included with this amplifier. There is also no need for an external radio load compensation network either. The Helix M Four DSP amplifier has an advanced radio load compensation circuit built-in. Helix amplifiers simply do not require the complex and bulky signal interfaces that all other amplifiers and DSP units require. This makes connections much simpler and much cleaner. 

Factory Harley Accessory Power Interface Included

No need to cut into the factory radio harness to get accessory turn-on power. A plug-and-play connection and cable are included.

Premium 8 Gauge 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.

Plug and Play Speaker Pod Connectors with Extensions

Don't cut any wires! we include plug and play connectors for the factory speaker pods in the fairing. This makes the installation easy. Simply plug into the pods and connect the speaker wire extensions into your new amplifier.

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 simple but special 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.
