Ultimate Harley Radio Flash & Equalizer (DSP) Combo Part# TECH-DSR1


Configure Your Harley Infotainment System Without Visiting the Dealer!

We recommend this combo kit for anyone who has high expectations and a factory Harley radio on a 2014 - 2020. This is the ultimate solution!

This combo kit allows you to flash your own radio unlimited times without going to the dealer plus it adds an EQ that converts your radios factory speaker outputs to 8 channels of high res RCA for direct compatibility with aftermarket amplifiers. This is the ultimate no compromise solution for aftermarket speaker and amplifier systems when retaining the factory Harley Radio. Good for simple two speaker systems or the very largest of systems with subs, lids, lowers, etc. There is no better option for factory radio integration with an aftermarket sound system. This is the very best!


All 2014 - 2020 Harley Radios including: Ultra models, CVO models, Scream'n Eagle models, Road Glide, Street Glide, & Electra Glide.
VIN locked to a single bike. Can not be used on multiple bikes. Not locked to a single computer. Can be used for unlimited flashes with unlimited computers. 

TechnoReasearch Radio Flash System

TechnoResearch Alaris Harley Radio Flash

This unit plugs into the USB port on your PC/Laptop and allows you to flash your own Harley radio for aftermarket sound systems (speakers and amplifiers). This unit is required in order to obtain a flat (friendly) EQ curve directly from your Harley radio. This part does not get installed on the bike. It simply plugs into the factory diagnostic port on the side of your bike and then is disconnected after you are done with the flash.

New Feature Added:
Enable CarPlay on your GTS radio!

Harley CarPlay

Capabilities: set radio to work with speaker kits/amps from American Hard Bag, Rockford Fosgate, Soundz, J&M, Kicker, WildBoar, and others. Enable WHIM, Bluetooth, CarPlay, or CB/Intercom features. Adjust BCM light functionality (LED turn signals/headlights, Aux light behavior, brake light behavior). Read and clear diagnostic trouble codes. 

DSR1 Digital Equalizer (DSP)

Rockford Fosgate DSR1 Harley Connections

This part is the second part of the ultimate combo and it gets installed in the fairing of your bike and it acts as a go-between for your factory Harley radio and all of your aftermarket amplifiers and speakers. Using a DSR1 in your system gives you ultimate control over the sound of each speaker in the system. It can be plugged into just the front speaker outputs or to both the front and rear speaker outputs of your factory radio and it gives you your choice of 2, 4, 6, or 8 channels of RCA out for your aftermarket amplifiers. The DSR1 eliminates the need for crappy high to low level adapters in your system. 


  • 8 Channels of high resolution RCA type outputs for aftermarket amplifiers
  • 8 seperate 31 band equalizers (4 pairs-one for each RCA output)
  • 7 band global equalizer for quick and easy tuning of entire system at once
  • Digital crossovers for each RCA output channel

Easy to Use

The DSR1 is controlled by a smartphone app via Bluetooth so that there is no need to ever plug into a computer or take your bike apart in order to make your audio adjustments. Also the DSR1 easily fits in any fairing along with any amplifier that we sell. The DSR1 has a "Basic" mode which presents you with a simple 7 band EQ for making your adjustments, or you can enter the "Advanced" mode for nearly unlimited audio adjustments. 


Note: This item is not returnable or refundable because once it is plugged into a bike it is locked to that bike for life.
