The Original Rumble Road™ Ultra Kit (Chrome) With Bluetooth Adapter

$ 299.95


Take the Ultra challenge. With more than double the peak power output and substantially HIGHER-gain input than MH Instruments' Original Classic Rumble Road™ Premiums, experience what are easily the best-sounding, loudest amplifier-integrated speakers available aftermarket!

Designed by MHI specifically for the demanding environments of motorcycles and other powersports vehicles, our high-output, high-fidelity stereo speaker system produces crisp, powerful sound even at highway speeds. Amplifiers are built into BOTH speakers for up to 200 watts of power capability* from your new audio system.

Designed by motorcyclists for other riders, MHI's proprietary built-in amps mean reliable, water-protected electronics "behind the grille," with no unsightly bags or visible add-on amps that add clutter or labor. Rumble Road™ Ultra is attractively packaged in lustrous chrome or black spotlight shells to enhance the look of most any motorcycle.

Easily installed on handlebars, engine guards, forks, utility bars or other locations, the weather-resistant Rumble Road™ Ultra speaker system works with most smartphones, portable MP3 players, satellite and marine radios, and other personal stereos featuring a standard mini-plug headphone jack. Rumble Road™ amplified speakers provide high-quality sound on the go or while parked.

To install, simply wire up to a switched and fused 15-Amp, 12-Volt source on your bike, hook up your favorite smartphone or portable stereo using the supplied cabling and enjoy! No external amplifiers ensures a very clean look. (NOTE: If you do plan to use a car stereo instead of a personal stereo, check out MHI's non-amplified Rumble Road™ Limited speaker system).
