Flash Your Own Harley Radio as Many Times as You Like! Try out Different Configurations. Flashes OEM Harley radios for Harley OEM sound systems and aftermarket products. Often required to obtain the desired flat EQ curves. Compatible with 2014+ Harley ECUs and Radios. We recommend flashing bikes with aftermarket amplifiers and speakers with the Rockford Fosgate tune. This tune gives you a great EQ curve, front to rear fader control, tone controls, and retains the speed dependant variable volume feature along with a much wider usable volume range.
