Where this fits in the build
Vehicle-specific and open-air equipment should be chosen around fitment, environment, placement and the output needed where the system will actually be used.

ARC Audio RG15 Road Glide Amplifier Mounting Bracket
The amplifier is small enough to fit in a Road Glide fairing, but that does not mean it should be hung wherever there is open space. The RG15 gives the compatible ARC amplifier a defined mounting location in the fairing without cutting or modifying the factory support structure.
ARC designed the plate to sit above the fairing structure and under the radio, placing the amplifier in the same general area Harley uses for the factory Boom Audio amplifier. That keeps the install cleaner, makes service easier and avoids fabricating a one-off bracket when a purpose-built plate already exists.
Fitment
- 2015–2023 Harley-Davidson Road Glide applications
- ARC Audio MOTO 800
- ARC Audio MOTO 720
- ARC Audio MOTO 600.4
- ARC Audio KS125.2 Mini
Important: use the hardware specified for the amplifier being installed. ARC notes that MOTO 800/720 installations use the small black amplifier mounting screws supplied with the amplifier together with the larger washers from the RG15 kit.
Why use the RG15
If the system plan already calls for a compatible ARC amplifier in a Road Glide, the RG15 removes the mounting question. It is not a signal interface or wiring harness; it is the mechanical piece that keeps the amplifier located and secured without modifying the fairing support structure.
Fitment note: verify the exact motorcycle generation and amplifier before ordering. The newer 2024-generation Harley architecture uses different mounting and integration hardware.
