Our Favorite 4 Channel Amplifer
The RZA1000.4 is the very best-sounding amplifier made specifically for Harley use. This amplifier has better speaker cone control at high volumes for better bass, and far better high frequency fidelity than other amplifiers. Natively compatible with factory Harley radios and aftermarket radios alike, the RZA1000.4 has a super wide range input (.41 to 10 volts) that is balanced so that it can accept anything from a standard line level RCA to a high voltage speaker level input directly from a factory radio. And it does this without the need for any noisy line levelers. This amplifier uses a far superior internal power supply to other amplifiers and can sustain extreme performance where other amplifiers just run out of gas and clip or drop in volume. This is a beast of an amplifier in a small footprint. This amplifier features a full chassis heat sink for more performance in a much smaller size package. The full chassis heat sink also allows for the amplifier to be mounted in any position and to keep cool even on the hottest summer days.

your part is guaranteed to fit
We test fit every part we sell on actual bikes in order to verify fitment on each moden, generation, and in each possible location. 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.
