Extreme Motorcycle Speaker System BLUETOOTH EDITION
Extreme Motorcycle Speaker System BLUETOOTH EDITION
1 of 6 (Enlarge)
 Choose the size of the speakers, our standard size is 4" speakers, but we offer an upgrade to a 5.25" speaker which is 31.25% more speaker area than our 4" Speakers, the 5.25" Speakers will Play Louder and Hit Harder, BUT they are bigger about 6" Diameter housing so putting them on the handlebars might be a bit much, most customers install them on the crashbars.

More Power + More Speakers = Awesome. 

320 Watts RMS - True Actual Power 
That is 80 watts of continuous power to each speaker. 

We start with FOUR top of the line Kicker KSC404 Speakers and paired them with an awesome 4-channel Diamond Audio amplifier that is very small and extremely powerful. The result is Loud and Clear.  But why 4 speakers? It's all about better quality and louder volume that's why. We can only squeeze so much sound out of two speakers, and that might be ok for those other guys, but not for you. There are no compromises with this system.  80+mph, Loud Pipes, No Windshield, NO PROBLEM


This system is very loud with distortion free music. 

Kicker Speakers in  Metal Housings
Diamond Audio Amplifier
Bluetooth Edition (Pair with your phone for wireless audio)
AUX Input (connects to standard headphone jack of your favorite audio device)
Handlebar Mountable Remote Control (glove friendly design)
Handlebar/Highway bar mountable speakers
Complete Easy To Install Kit
Built In Abilene, Texas

If you choose the 5.25" they are on the bigger side, so please make sure you have room on your handlebars/crashbars to mount the speakers, and room in your travel trunk/saddlebag for the amplifier. 


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. 

Installation couldn’t be easier
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.

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.

Incredibly Loud

Fantastic system, look and sound great. Plenty of power, easy to install, and looks great. Best sounding speakers I've heard on any bike, steel horse, Rumble Road, J&M, none of them sound as good as these speakers.

These speakers are great and sound awesome!

Very surprised how good they sound. I have a Suzuki with loud Cobra Long Shot pipes and a 3/4 helmet on and i was still able to hear the music nice and clear at high speeds. Great product.
