About Us

Founded in 1995, Southern California-based MH Instruments (MHI) designs, manufactures and distributes consumer electronics products for motorcycles and other powersports applications. As avid riders ourselves, we developed The Original Rumble Road Speakers for other riders to enjoy.


MHI strives to meet the needs of savvy riders who want performance and overall best value in powersports accessories. By designing consumer electronics using “off-the-shelf” materials versus customizing, and by maintaining a “Made-in-the-U.S.A.” focus, MHI provides quality, affordable products that powersports enthusiasts can buy with confidence and pride. Please don't settle for copycat designs of our Rumble Road speakers.
