So Cal Auto Sound 5.25in Custom Black Weather Resistant Speakers

Premium Custom Powder Coated Black speakers with FULLY MARINIZED Polk Speakers.

Very similar to our 4in speakers, but with a larger speaker in a larger housing.  Provides a bit more output when you have the room.  Can be mounted on the handlebar of some bikes, but usually used on the crash bar.  Upright or upside down.

We provide 6ft of pure copper speaker wire, because we know your amp isn’t always going to be a few feet from your speakers. Price is per pair.

These are sold with high quality black clamps.  Please measure and choose the correct size.

Non-amplified, so you will need to use a separate amplifier.

The shells are 6.125in in diameter and 4in deep

Hand built in the USA.

So Cal Cycle Sound  Custom Chrome or Black Motorcycle 4in Speaker Kits

Everything you need for serious sound on your bike. Premium Custom Chrome speakers with FULLY MARINIZED Polk drivers with true 100w RMS  Class-D “Ugly Amp”, Bluetooth controller with bar mount…everything you need.  All the top quality components we use on our own professional installations.

Yes, you read the right, this kit uses our own amplifier and it’s UGLY.  Why do we build our own amplifiers?   Because all of the amplifiers out there are either way too big or very wimpy.  This amp is half the size or less than the amplifiers provided in competitors kits, yet pack full size amp power.  Other micro amps may quote big power numbers, but in reality they are more like 15w RMS true power.  This tiny little amp has a true Class-D amp that will put out 50w RMS power into each speaker all day long.  Why it it ugly?   Because it’s got a ton of heat sink space and no box to cover the ugly stuff.  Besides, it’s so tiny you’ll be hiding it anyway.

Check out the video: 

The “Ugly Amp” has two outputs for the two speakers, one 2ch input that plugs directly into the supplied Bluetooth controller, and a power and ground. It’s already tuned with the proper HPF and Gain settings for the speakers, and matched perfectly with the BT controller.  Each of our custom “Ugly Amps” is run on an Amp Dyno at full power for 4 hours before it’s sold.

So Cal Cycle Sound  Custom Weather Resistant Speakers WITH INTERNAL AMPLIFIER!!!

We had these specially powder coated for a customer who decided to move up to the Quad4.  Powder coat operation is normally an extra $80.  Special deal on this pair only.

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.
