Arc Audio Motorcycle Audio Kit (4 Ch Amp / MOTO602HD Speakers – HD ’14 – up)

SKU: MPAK14HD Category:
Model No: MPAK14HD


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 the PSM 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.

MOTO602HD Horn Drivers: If you have to have the loudest bike on the block, this MPAK is for you. The MOTO602HD speakers offer a lighter woofer cone and more compliant suspension. The tweeter features a unique horn-loaded design that extends through the center of the driver. The huge titanium tweeter diaphragm has a diameter of 1.25 inches. Whether you are rocking out to AC/DC or Zeppelin, your tunes will come through loud and clear, even with the throttle cranked on the freeway. The HD speakers include the same UV and weather-resistant features as the MOTO602 V2.

Adding the optional ARC Audio PSM 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 MPAK14 includes speaker adapters to let either speaker option bolt into the factory location and work with the enclosures in the fairing. Likewise, the kit includes dedicated power wiring to ensure efficient current delivery to the amp. Finally, 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 intact!

Designed for use with 2014 and up Harley Davidson Street Glide and Road Glide Motorcycles.
