Product Overview
This is the new J&M STAGE-4 ROKKER® XXR Custom 2-speaker &
amplifier installation kit for your 2015-2018 Harley RoadGlide or
RoadGlide Ultra with the Harley BoomBox 6.5GT Premium or 4.3
standard radio.
At the very heart of this system is our in-fairing mounted 2 chan-
nel ROKKER XXR amplifier rated @ 165w RMS per channel X 2 to
provide up to 330w total RMS power!
The amplifier will be custom tuned for use in conjunction with
your specially FLASHED Harley Infotainment radio (Diag4bike
digital technician “J&M Audio Custom” menu option), to provide
THE BEST on-highway volume, clarity and overall performance
available, from your music source selections of FM stereo, XM sat
radio, Smartphone or USB thumb drive.
Included are J&Ms fully weatherproof 6.71” ROKKER XXR speak-
ers featuring a high-tech woven-fiber woofer cone & a massive
high-density high-flux strength Neodymium magnet structure with
large center & perimeter positioned voice coil cooling vents, to pro-
vide for maximum heat dissipation when operating at high volume
levels for extended periods.
The custom designed speaker grills with mounted high-output
dome tweeters are also weather-proof and shock-proof for maxi-
mum long-term durability.
This STAGE-4 ROKKER XXR custom installation KIT has been engi-
neered to be 100% plug-and-play for your convenience during the
installation and to maintain the complete integrity of your Harley’s
internal wiring harness.
The new J&M music-source test USB thumb-drive is also included
for your performance comparison testing.
