Installation Instructions
1. Remove the outer fairing shell, seat, and fuel tank.
2. By following along the factory wiring harness, route the
amplifier power harness from the fairing, under the fuel tank,
and on to the battery. (removal of the fuel tank is necessary for
proper installation)
3. Then route the rear speaker wiring harness along the
same path as the power harness to the rear speaker mounting
location.
4. 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.

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 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 amp kit and/or 7.25 speaker kit will fit with no additional parts or hardware needed.
