2 Speakers on the Handlebars + 2 Speakers on the Crashbars = 1 Big Smile on Your Face!

The Cerwin Vega amplifier powers 4 Kicker speakers for better quality and louder volume. We can only squeeze so much sound out of two speakers, but with four speakers and 1200 peak watts, this is the perfect prescription. +80mph, NO Windshield, Loud Exhaust, NO PROBLEM, this system is LOUD and CLEAR. This system is more powerful, louder, has a longer warranty and a lower priced that the competition. They make claims, but we state facts. Go ahead crank it up and twist that throttle but pick your tunes wisely because it is not just you listening anymore.


Every component of this system was selected tested and proven to outperform the competitors top tier 4” speaker systems in every category. This is not a claim, it is a fact. We start with top of the line Kicker 44KSC404 Speakers and paired them with an ultra-compact amplifier from Cerwin Vega that uses Class D technology with MOSFET output, that translates into this, it is very small and extremely powerful.

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

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 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 4" speakers on the market, so we became an AUTHORIZED Kicker Dealer and choose to use them in ALL of our systems.
