Premium Custom speakers with FULLY MARINIZED Polk Speakers and TRUE 50W x 2 RMS Continuous Power

These are the only truly properly amplified 4in speakers currently made.  Others claim outrageous power, but you don’t have to listen to them for long to realize you’ve been fooled.  Others claim “peak” power numbers which are meaningless.  These are true amplified speakers with their own 24v power supply and a 2 channel 100w RMS amplifier built in.  That’s why they are a little deeper than others.  THE DIFFERENCE IS SUBSTANTIAL!

For those who are technically minded we use a TPA3116 amplifier at 24v.  A quick look at the spec sheets for this well know class-D amplifier chip will verify our claims.

A small (2″ x 2″ x 1″) completely weather sealed power supply will need to be mounted somewhere.  This is what gives these speakers 2-3 times the output of others.  Many owners put this box on the front of the frame, but it can really go anywhere.

While no 4in speaker can match the capability of the 6in speakers on a full size fairing touring bike, these are at least pleasantly useful at any speed.  If you’ve ever been on a bike with other amplified mini speakers you know why this is so important.

Please check to make sure your bars are the correct size before ordering.
