THE Harley Radio FLASH Nightmare is FINALLY OVER!!!

The following is a list of the current programs available for the exciting J&M (digital signal processor) controlled audio amplifiers OR 630W ROKKER EXTREME Speaker/Amplifier kits with J&M RCA input harnesses with the large GREEN-BAND.

To be used with the 2014-2021 Harley BoomBox Infotainment Radios (GTS/6.5GT/4.3std) that have NEVER BEEN FLASHED from Stock Condition.

"IF" your Harley radio HAS BEEN previously flashed from stock, return to your Harley dealer and have it flashed back to stock condition as FOUR-SPEAKERS, UPPER-FAIRING, REAR-PODS, NO-AMP.

You can also utilize the Techno-Research or Diag-4-Bike digital technician consoles to flash the Harley radio back to stock condition (see video below).

This particular stock Harley flash will also activate the front/rear fader control and activate the rear channel audio outputs on the Harley radio, if you need them.

Prior to choosing and installing the specific program for your J&M ROKKER XXRP 700w amplifier, please download and/or print the download instructions as contained in the .pdf files below.

Should you have any questions about the specific programs or have any difficulty during the download process, you may send an email direct to [email protected] for assistance.

Special programming note: Using an incorrect DSP program which causes the amplifier to overdrive the speakers to extremely high volume and/or distortion levels, can and will permanently damage the speakers and this type of damage is NOT covered under the J&M speaker warranty.
