Introducing Vintage… Now available in one expanded kit for 1" bars, the Original Classic Rumble Road™ Premium system featuring built-in amps in both speakers AND CrankCase™, MHI’s custom volume controller/power switch combo! 

Enjoy one of the best sounding, loudest amplifier-integrated speaker systems on the market AND a classically designed, infinite-setting volume control together in one convenient, chromed Vintage package tailor-made for 1" handlebars. Designed by motorcyclists for other riders, Rumble Roads and CrankCase™ are well-suited for most personal stereo systems mounted in powersports applications – from FM, satellite and marine radios, to iPods and other MP3s, and CD and cassette players.

These are not automobile-purposed speakers. Designed specifically for the demanding environments of motorcycles and other powersports vehicles, MHI’s Original Rumble Road™ high-output, high-fidelity stereo speaker system produces crisp, powerful sound even at highway speeds. Amplifiers are built into BOTH speakers for up to 92 Watts of power* from your bike’s new speaker system.

MHI’s proprietary built-in amps mean reliable, water-protected electronics “behind the grille,” with no unsightly bags or amps that add labor or clutter. The Original Rumble Road™ Premium speakers are attractively packaged in lustrous chrome spotlight shells to enhance the look of most any motorcycle.  And, MHI’s speaker system works readily with any portable stereos featuring a standard miniplug headphone jack.

CrankCase™ is housed in precision-machined and chromed lightweight billet aluminum. CrankCase™ features an oversized knob that gives you smoother, more comfortable through-the-glove feedback and control of your stereo system’s volume output.  CrankCase™ makes itself even more useful by turning your complete sound system on and off with an audible click you can also feel, while MHI’s signature blue LED visually confirms power on or off.  And, the unit’s built-in output amplifier is designed to drive standard portable headphones in the event you prefer to keep your tunes to yourself.  Learn more

To install the Vintage kit speakers, simply wire up to a switched and fused 12-volt source on your bike, hook up your favorite portable stereo using the supplied cabling and enjoy! No external amplifiers required 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.) CrankCase™ installs easily on 1" handlebars, spotlight mounting bars or forks using the custom mounting hardware supplied with the unit. Simply wire it up to a 12-volt source on your bike, connect to your amplified speakers and stereo system, and enjoy!
