Overview
Infinity Kappa Speakers
Our absolute favorite speaker system for bolt in and smile results. This speaker system is the nicest sounding setup right out of the box that we have ever encountered. The speakers can be added to a Harley without complex tuning. You simply get an instant jump in output and sound quality by installing them.
A Powerful Waterproof Amplifier That Is Easy to Install
Designed specifically for Harley applications, the JBL PA1254 amplifier is well suited for extreme sound quality in demanding conditions. Easy setup with built in crossovers and a very friendly balanced signal input stage, the PA1254 is all about perfect form and function. This is one of the friendliest amplifiers to install and set up for any Harley application. Pair the optional plug and play wire harness kit for a super smooth and quick installation.
Future Upgradeable
Although these speakers work spectacularly well without a sound processor, they are even better with one. So if you want another great performance boost down the road, you can always add a sound processor (DSP) to get another huge boost in sound quality. The Infinity Kappa speakers are capable of hanging with some of the most expensive sound quality speakers on the market.
The best DSP to add to this system can be found here.
Look No Farther
If you are looking for a guaranteed high performance result and no fuss installation, this is the system you want.

You can be sure that if we have stated that a part fits your bike, that it will, or your money back. You will find model, year, and location fitment details on most product pages.

We thoroughly test every part we sell on a real bike
There are a lot of parts out there that we refuse to sell. If it’s not up to our high standards, it never makes it to this website. We have parts that fit various budgets and levels of insanity, but all parts we carry are exceptional performers.

WE ARE FULLY AUTHORIZED RETAILERS FOR ALL BRANDS WE SELL
There are only a select few authorized online retailers for the brands we sell. Most all online retailers (even the really big ones) are not authorized at all! And the manufacturer’s warranty is void before you even get your items.
