TRABUCO CANYON, CALIF., Nov. 24, 2009 – Powersports electronics developer MH Instruments (MHI), has introduced a powerful and versatile 200-Watt external stereo amplifier that motorcycle riders can use to upgrade an existing sound system, design a new one or add a second set of speakers to their cruisers, baggers or touring bikes. MHI pioneered stereo speakers with built-in amplifiers, which the company introduced in 1997 as the original Rumble Road™ speakers.

“The Rumble Road™ HD Raw200 is a workhorse amp that will always have a place in a bike’s audio setup,” said Mauro Dresti, MHI co-founder. “It’s such a versatile star performer and looks so good chromed, riders will want to keep it around for use on their next bike,” Dresti said.

Explaining the new 200-Watt stereo amplifier’s versatility, Dresti said MHI’s custom chromed, high-power HD Raw200 can be used:

• as a stand-alone amp to power personal stereos – including MP3, satellite and CD players – and a pair of fairing- or externally mounted speakers
  
• with factory-equipped or aftermarket stereos, from car stereos, to satellite and marine radios, to CD changers
  
• to make an existing audio system better by upgrading the amp or by adding a second pair of high-power-handling speakers
  
• in saddlebags or fairings, or displayed openly – anywhere on the bike that maintains good airflow for optimal performance
  

The HD Raw200 amplifier’s compact size adds to its versatility. The billeted and chromed aluminum case, together with its integrated mounting bracket that doubles as a heat sink, measure 3.9 inches wide by 5.3 inches long by 1.6 inches deep overall.

Engineered for the demanding environments of motorcycles, the HD Raw200 is feature-packed, with built-in conveniences designed to cover most installation scenarios. Foremost among these built-ins are the HD Raw200’s high-gain, stereo-bridged amplifiers, each of which produces approximately 70 Watts continuous (100 Watts peak) output into 4 Ohms per channel at 13.6 VDC. Bottom line? 200 Watts peak output per system.

Installation conveniences built into the HD Raw200 include an on/off relay for remote switching; a designed-in universal line-level input feature for compatible hookup with most stereo installations, including CD changers, satellite radios and marine radios; universal high-level inputs for added boost; a ground loop isolator for easier wiring and sound enabling; and a power filter to reduce noise from harsh electrical systems on bikes.

The HD Raw200’s state-of-the-art but still “off-the-shelf” surface-mounted internal circuitry promotes audio equipment compatibility, reliability and durability. The amp can be wired directly to any onboard 12-Volt source using standard RCA connectors packaged with the amplifier.

MSRP for the HD Raw200 stereo amplifier is US $299.95. A complete kit for fairing-based bikes includes two 5.25" coaxial speakers and acoustic foam baffles for $349.95.
