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.

Tech Specs - of Speakers and Amp are listed below


Simple Installation: Instructions are included, but our kit is designed to be easy for self-install. Basically, the system wires to positive and negative battery terminals, and to a switched and fused power supply on your bike (headlight wire/fuse box) so that it turns on/off with the key. Then the speakers connect to the amplifier by the butt connectors. The amplifier either plugs into the headphone jack of your device, or to the Bluetooth controller, and you're are ready to ride! We made the installation simple, but if you don't feel comfortable contact your local car audio shop and they can install for you. 

The amplifier can be mounted in a saddlebag, travel trunk, or in a tool/fork bag like one of these SampleBag1SampleBag2

  • Easy Installation
  • Highway Rated for 80mph+

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" and 5.25" speakers on the market (including Polk, Infinity, JBL, Pioneer, Kenwood, Alpine, Rockford Fosgate to name a few). We selected the Kicker KS-Series Speakers as the best sounding and best preforming speakers. When paired with the Cerwin Vega amplifier these Kicker speakers played louder with less distortion and deeper bass response. We 100% believe that these Kicker Speakers are the BEST sounding speakers on the market, so we became an AUTHORIZED Kicker Dealer and choose to use them in ALL of our systems.
