Product Description
This exciting new J&M 250w fairing speaker amplifier kit has
been designed specifically for use in the 2006-2011 Harley®
RoadGlide fairing, with the Harley HK radio. (may also work
with the 1998-2005 Harley RoadGlide fairing/radio, under the
certain conditions below)
This is a full range class G amplifier and is spec'd at
125watts RMS per channel, both channels driven,
continuous into a 2 ohm load @ 14.4vdc, 70watts RMS
continuous into a 4 ohm load.
IMPORTANT NOTE: Some 1998 thru 2005 model Road-Glides require the replacement of the factory grill assembly/speaker adapters in order for
the J&M 250w amp kit and/or 7.25 speaker kit to be installed. It will be necessary to remove the outer fairing and inspect the factory installed
grill/adapter assemblies to determine if they need to be replaced. The early style assemblies can be identified by the method of attachment to the
inner fairing. If the screws attaching the speaker go completely through the grill/adapter and into the inner fairing mounting bosses you have the early
style assemblies and they will need to be replaced with the later style factory grill/adapter assemblies and mounting hardware listed below. The later
style grill/adapter utilizes independent hardware to attach it to the inner fairing then the speaker is attached to the grill/adapter with 4 additional
screws. If you have the later style assemblies, the J&M 250w amp kit and/or 7.25 speaker kit will fit with no additional parts or hardware needed.

and on to the battery. (removal of the fuel tank is necessary
for proper installation)
3. After first disconnecting the negative battery cable from
the battery, connect the positive (red) lead from the amplifier
power harness directly to the positive post of the battery.
Then connect the negative (black) lead from the power
harness to the same bolt/stud on the frame that the
negative battery cable is connected to. Then reconnect the
negative battery cable to the battery. (Figure A) Do not
