Please contact your local distributor for current pricing and availability. 


Designed for 2014 and newer Harley-Davidson Road Glide and Street Glide touring motorcycles, the ARC Audio MPAK14 is the ultimate audio upgrade kit on the market. We’ve combined our motorcycle and powersport speakers with the amazing MOTO720 amplifier and included the “option” of adding the PSM-Pro digital signal processor to ensure your system sounds great. Curious about how it all works? Keep reading!

The MOTO720 is our second-generation motorcycle-specific amplifier. Other companies have copied its design but can’t touch its performance. Our electronics design team is unparalleled in the industry. Transparency, detail, and efficiency are just some of the words industry experts use to describe ARC Audio amplifiers. The MOTO720 is designed to fit on top of the factory radio without ANY modifications. It may sound weird to some, but we include industrial grade hook and loop fastener tape to mount the amp. Why? Because we don’t want to affect the structural integrity of your bike by suggesting a modification that will void the bike's warranty.

The angled top of the amplifier allows it to fit under the stock fairing while maintaining adequate heat sink size to ensure the amp won’t shut down, even when you leave the volume cranked for hours. Don’t let yourself be fooled by imitators – this amp has the crystal clear, low-distortion sonic signature that has made ARC Audio the choice for music lovers, enthusiasts, and riders around the world. Designed for the motorcycle environment, the MOTO720 boasts an efficiency rating of over 96%! What does this mean to you as a motorcycle owner? Less power draw from your motorcycle and less demand on the charging system so you can listen to your music as loud as you want.

This MPAK14HD is equipped with the MOTO 602HD Horn driven speakers designed specifically for motorcycle applications. They include UV-resistant materials that ensure the speakers won’t chalk, fade or crack after only a few months. These high-efficiency speakers combine a low-mass woofer cone with a massive horn-loaded tweeter to deliver amazing output. A large-diameter voice coil design ensures great power handling and long-term reliability. If you want to drown out wind noise at 75 miles an hour or the rumble from a custom exhaust, the MOTO602HD speakers are the right choice.

Speakers designed for motorcycle applications need to be able to play loud for hours on end. All MOTO-Series speakers are designed using high-temperature voice coil windings and formers to manage heat efficiently. The result of these upgraded components is more output and reliability than competing solutions from other brands. Are you thinking, “Hey, they’ve thought of everything!” Well, that’s what you get from the company that pioneered motorcycle audio upgrade packages.

That radio on your bike is a complex little design. Harley asked their supplier to include some downright strange signal processing to give the factory audio system a unique sound. Adding the optional ARC Audio PSM-Pro digital signal processor to the MPAK14 kit is the best way to deal with this strange acoustic tuning. We include an EQ curve that undoes the one built into the radio so your speakers will sound amazing. There’s no need to reflash anything or worry about voiding the electronics warranty on your new Harley. Likewise, you don’t have to deal with the hassles of having the radio flashed again after taking the bike in for maintenance or service. It just sounds great, all the time.

The PSM-Pro digital signal processor gives you the ability to fine-tune the sound and tone of the system to your specific listening style and preferences, just like the sound engineers do at a concert. The result is a smooth and natural performance that brings out the finest of details in your music.

As the MPAK14 is a full kit, it includes everything you need to get your music upgrade completed. The kit includes dedicated 8-awg power wiring to ensure efficient current delivery to the amp. And the signal wiring uses OEM-compatible connectors to extract a signal from the factory radio and feed it to the DSP or MOTO720 amp. Not a single wire needs to be cut, tapped, or modified in any way, so your warranty remains unquestionably intact while you can enjoy your music the way it was supposed to be enjoyed – loud!

Depending on the speaker and DSP combination you choose, the PSM-Pro may come in a separate package from the amp and speakers.
Road Glide amplifier mounting plate (RG-15), is included in all MPAK14 kits, but will not be used in Street Glide installations.
