The Perfect Solution

High to low, equalizer, crossover, Bluetooth all in one plug and play unit. This kit uses the awesome new Rockford Fosgate DSR1 digital sound processor to seamlessly integrate aftermarket amplifiers and speakers with your factory or aftermarket Harley radio. 

All high-performance systems need this part! It is industry standard to use this sound processor to make a factory Harley radio perform and integrate with aftermarket speakers and amplifiers, but it also plays a critical role in systems with aftermarket radios as well. Many very important system features can not be found with an aftermarket radio alone.

Aftermarket & factory radios both need this part if you have high expectations of your system.

Simple to Setup 

The setup is straightforward and done by smartphone (Bluetooth). We can even make your settings for you remotely at no extra cost!

Easy to Use 

A simple smartphone app controls all of the settings. No need to connect to a computer.

No Need to Flash Your Bike!

The equalizer can account for whatever flash your bike currently has. The plug-and-play signal harness comes with load resistors built into it that dramatically improves the sound quality of your factory Harley radio.

Note: We supply an EQ file that will give you perfect frequency response as long as your radio has the factory 2 speaker/no amplifier flash (most bikes have the standard 2 speaker flash). If your bike is any other configuration or if you have had it flashed to another configuration you will need to set the EQ on the DSR1 manually or have your radio flashed back. We do not have files for alternate configurations.  

Easy to Install 

This kit will work with any radio, factory, or aftermarket. Optionally it even ships with plug-and-play signal adapters for any '14 or later Harley Davidson radio. The DSR1 also has RCA inputs as well for aftermarket radios.

Additional DSR1 specifications and features include:
• Frequency response: 20 - 20k +/- 0.5 dB
• 239 Bands of equalization for aftermarket tuning
• Adjustable crossovers with selectable slope and crossover-type
• Crossover Frequency: 20 - 20k Hz
• Time Alignment of up to 10msec of delay on each channel
• Bluetooth 4.0 connectivity for convenient setup
• Interactive Tuning Interface Controlled via Android/ iOS App
• Optional PLC2 Level Controller with assignable functions
• Dimensions (L x W x H): 5.12 in. x 4.04 in. x 1.26 in.
• CE Compliant

The optional signal and power interface harnesses below are not required if you are using any of the amplified full systems by Rockford Fosgate that include the RFK-HD14 installation kit. These kits come with a T harness that already gives you a front signal, rear signal, and power.

For all systems not using the Rockford Fosgate RFK-HD14 installation kit, these harnesses are required. 

OPTIONAL Front Plug & Play Signal Harness for '14 and up Harleys Is Available with This Kit. 

Front signal harness for DSR1 Harley Davidson

This harness includes the connectors that plug into the factory radio to grab signal as well as two new plug-and-play speaker harnesses that go from your aftermarket amplifier back to the front speaker pods. 

Note: The front plug and play harness are shown as an optional part that will not ship with this item unless it is selected as an add-on at checkout for $69.99. 

Optional Plug & Play Power Harness

DSR1 Power Harness

This harness supplies fused power to the DSR1 using the CB option harness that exists in all Road, Street, Electra, and Ultra Glide models even if you do not have the CB option. Along with the appropriate signal harness, this makes power connections totally plug and play. Note that the only wire that will not have a plug-and-play connector on it is the remote out for your amplifier(s). This is a simple one-wire hookup and most all amplifiers have a screw type terminal that is designed to accept a remote wire without a connector. We highly recommend this option for all Road, Street, Electra, and Ultra Glide models.

Note: Bikes that do have a factory CB option installed will need our CB "T" harness instead. You can find that harness here.

OPTIONAL Rear Plug & Play Signal Harness 

Rear Harley Davidson Radio Signal Harness

If you would like to keep or enable your factory fader control, you can optionally purchase the rear signal harness for $69. Note: If your bike came from the factory with only two speakers you will need to have the radio flashed for 4 speaker operation in order to use the rear signal harness.  

OPTIONAL Rear Plug & Play Signal Harness for Ultra Models. 

Rear Signal Harness for Harley Ultra Models

Ultra models do not have a rear signal available at the front of the bike. The rear signal is available through the tour pack plug near the back of the bike. We make a special harness for these bikes that gives you a "T" harness that goes in line with the tour pack and gives you both signal and speaker outputs up at the front of the bike. This harness has a 7 business day build time before shipping

Please be sure before you decide to purchase.

This product has a 15% restocking fee if you cancel your order. Returns are not accepted on this item if you simply change your mind. We understand that there are a lot of settings associated with configuring a sound processor and that's why we offer free setup files and free support. We also have done more documentation on how to set up your DSR1 than anyone else on the planet. 

A basic understanding of crossovers and equalizers is required! If you are looking for a solution that does not require any configuration this is not the product for you. 

Feel free to give us a call if you have any questions about the DSR1 or how it should be set up for your particular system. 1(888) 311-0016
