Amplifier hooks to battery terminals, connect speakers to the amp, and plug the Bluetooth into the amplifier and then wire it the battery terminals and to a switched +12V wire (like headlight wire). Then when you start the bike the system turns on/off, there is also an optional hookup method where the system only turns on after you push the power button.

RMS power is true actual power, really the only way to judge what a amplifier makes or a speaker can take. The Diamond Audio amplifier delivers 200 watts RMS to each speaker (200x2). More than twice the RMS power to each speaker than our competition.  We selected top of the line Kicker speakers are matched to the amplfiier and just really sound awesome when they are cranked up. 


Bluetooth Edition with AUX Input, which means you can wirelessly connect the system to your Bluetooth enabled device.  If you don't want to use the bluetooth, then the system also has an AUX input so it can be plugged into the headphone jack of your favorite audio device. The remote control is glvoe friendly for easy control while riding, a quick turn in either direction will advance the sound, while turning it in either direction while holding it there will adjust the volume. The remote can be mounted handlebar or if you don't use the bar mount, it can use the existing bolts on your bike to mount to the clutch/brake.

Amplifier Specs

Sound quality in a small footprint chassis can be found with Diamond Audio’s Micro series amplifiers.  Featuring the ultra-efficient full-range Class D topology, these compact amplifiers deliver serious power making it the best in class.  Installation possibilities are endless due to its size and power amplification output.   Even with its small platform, performance and sound quality is never sacrificed with Micro amplifiers from Diamond Audio!  

Big power, compact, great crossover features, runs cool, and is spectacular looking. This amplifier easily fits in the fairing or tucked away in the corner of a saddlebag.

Speaker Specs

Why do we use Kicker Speakers? - We are serious about the components of our products, we cannot make the best products, unless we start with the best components.  Before we selected a speaker to use in our systems we ran vigorous lab test, road test, and conduct blind sound test of all high end 4" speakers on the market (including Polk, Infinity, JBL, Pioneer, Kenwood, Alpine, Rockford Fosgate to name a few). We selected the Kicker KSC404 Speakers as the very best sounding and best preforming speakers. When paired with the Diamond Audio amplifiers these Kicker speakers played louder with less distortion and deeper bass response. We 100% believe that these Kicker Speakers are the BEST sounding 4" speakers on the market, so we became an AUTHORIZED Kicker Dealer and choose to use them in ALL of our systems.
