What types of audio devices can I hook up to the HD Raw200 amplifier?
Rumble Road™ HD Raw200 works with virtually any portable stereo radio, or MP3, CD or cassette player featuring a standard 3.5mm mini-plug headphone jack, high-level speaker input adapters or standard RCA plugs. With the exception of non-standard and/or inexpensive FM radios with floating ground outputs, most brands work. The HD Raw200 also performs well with satellite and marine radios, as well as with traditional car stereo setups that have line outputs. For the relatively few devices manufactured with the newer 2.5mm stereo jacks, adapters are available from electronics stores.

Can I use any personal stereo with the HD Raw200?
You can use Rumble Road™ HD Raw200 with virtually any personal radio, or CD, cassette or MP3 player equipped with a standard 3.5mm mini-plug headphone jack. As noted above, for the relatively few devices manufactured with the newer 2.5mm stereo jacks, adapters are available from electronics stores. Products with "floating ground" amplifiers, such as very low-end FM radios, may not work optimally with MHI audio components.

Can the HD Raw200 amplifier be used with a conventional AM/FM car stereo or amplifier?
Yes, Rumble Road™ HD Raw200 works with most car stereos or amplifiers equipped with line-level outputs or high-level outputs. The HD Raw200 features built-in universal line-level inputs and universal high-level inputs, and includes standard RCA plugs for easy interfacing with conventional AM/FM car stereos.

Can I get even more power out of my car stereo’s outputs by adding an HD Raw200 amplifier to my existing system?
Yes, typically. The HD Raw200’s inputs are floating and can be used with ground-referenced or bridged car stereo outputs.

Will Rumble Road™ HD Raw200 amplifiers work only with Rumble Road speakers?
No, the HD Raw200 works with most any non-amplified speaker assembly – not just product manufactured by MHI. If you prefer to work within the MHI system, however, you will want to go with the full kit that includes speakers and acoustic baffles, or MHI’s Rumble Road™ Limited (non-amplified) speakers. Both 4-Ohm and 8-Ohm speakers can be used; however, if 8-Ohm speakers are used, expected power output from the HD Raw200 will be reduced by half.

What kind of sound output can I get from the Rumble Road HD Raw200?
Our high-gain, stereo-bridged HD Raw200 amplifiers produce approximately 70 Watts continuous per channel, 100 Watts peak per channel, into 4 Ohms @ 13.6 VDC, with impedences ranging from 4 to 8 ohms. Bottom line: The amp produces 200 Watts peak per system.

How big is the HD Raw200 amplifier? How much does it weigh?
The small-footprint billeted and chromed aluminum case and matching integrated mounting bracket together measure approximately 5.3” long by 3.9” wide and 1.6” deep plus cabling. The HD Raw200 amp weighs 1 lb. 15 ounces, including assembled (built-in) cabling.

Where can I install the HD Raw200 amplifier?
Measuring approximately 5.3” long by 3.9” wide and 1.6” deep, Rumble Road™ HD Raw200 is compact enough to fit just about anywhere – out in the open, or under wraps. It was specifically designed to stow away conveniently in fairing-based tourers, cruisers, baggers and other bikes where big sound and minimal space are “must haves.” However, its gleaming chrome, minimalist design and water-resistance assured by a custom-fit lid screwed at 14 points make the HD Raw200 suited for showcase locations, too. Any location you choose should allow good airflow over and around the HD Raw200 housing in order to prevent overheating the amp.

Can I connect the HD Raw200 amplifier directly to the battery?
Rumble Road™ HD Raw200 is ready to wire either directly to a 12-volt battery positive lead or to another positive 12-volt source on your bike, such as an existing accessory line or headlight power line. The color-coded audio cabling and power wiring includes 2 RCA patch cables and one Y-adapter to connect the RCA inputs to a standard 3.5mm stereo plug. If you need assistance, your local automotive sound shop or motorcycle dealer should be able to help you find a suitable power source, as well as properly install the system.
The HD Raw200 includes a built-in on/off relay with control wire allowing the unit to be turned on and off through a small switch or positive 12 VDC signal, such as that which comes from some car stereos with power antenna interfaces.

Can I use a power adapter to run my personal stereo off my bike’s power system instead of using the batteries?
Yes; however, please be aware that some personal stereos used in this configuration may produce ground noise, which is characterized as a high-pitched whine and occurs whether the engine is on or off. Systems amplified by the HD Raw200 avoid the noise issue because the amp has a built-in ground loop and power filter. This remedy eliminates any ground loops — and most of the resulting noise — between the two systems -- especially in satellite radio systems.

Will HD Raw200 work with two sets of speakers?
Each Rumble Road™ HD Raw200 has dual- (or stereo-) bridged amplifiers, so you will need one HD Raw200 for each pair of non-amplified speakers installed on your bike. Some of our customers have cleverly installed "quad" mounts — one pair of Rumble Road™ speakers on the handlebars and an opposing pair astride the passenger seat. If you still can’t quite picture it, this approach is beautifully illustrated by one of our customer testimonial montages.

Is the HD Raw200 amplifier waterproof?
Rumble Road™ HD Raw200 is water-resistant, meaning that it can tolerate splashed water and rain, but it is not literally waterproof and cannot tolerate submersion.

Return to Top


Are HD Raw200 amplifiers prepackaged with mounting hardware, or do I have to order hardware separately?
For your convenience, each Rumble Road™ HD Raw200 arrives assembled with an integrated mounting bracket featuring four long screw slots, ready to mount with your preferred screws depending on the mounting location you select.
