Step 1 – Mounting Plate and Bracket Mounting
With the front faring removed. Using the Type(4) bracket, align bracket on the bottom side of the mounting plate using the bracket type indicators. On the top edge, you will screw in the two threaded pins into the mounting plate. These are used to align the mounting plate with the rubber bushings on top of the factory radio.

HD Street Glide 98 – 13
Step 2 – Mounting Plate and Bracket Mounting
Using the Type(1) and Type(4) brackets, align bracket on the bottom side of the mounting plate using the bracket type indicators. On the top edge, you will screw in the two threaded pins into the mounting plate. These are used to align the mounting plate with the rubber bushings on top of the factory radio.

Step 3 – Amplifier Mounting
Mount amplifier upside down with the supplied screws to the mounting plate. Align the amplifier to the appropriate holes on the plate.
HD Road Glide 98 – 13
Step 2 – Mounting Plate and Bracket Mounting
Using the Type(2), Type(3), and Type(4) brackets, align bracket on the bottom side of the mounting plate using the bracket type indicators. After you have the bracket attached to the mounting plate, remove the clutch side fairing bulkhead nuts. Place the bracket over the studs pushing the bracket upwards while tightening down using the factory hardware.

Step 3 – Amplifier Mounting
Mount amplifier upside down with the supplied screws to the mounting plate. Align the amplifier to the appropriate holes on the plate.

Amplifier Wiring

Once the amplifier is mounted, you can now begin plugging in the wiring harness in their appropriate sockets. Plug the switched power harness into the 2-pin amp connector on the throttle side of the fairing. Note: Be careful when plugging in the harnesses to the appropriate socket. The 4-pin Molex plugs for the Input / Output Harnesses fit in both sides of the amplifier.
Step 4 – Fairing Speaker Wiring
Unplug the factory speaker wires from the speaker and plug them directly into the Front Speaker Input Harness. These are labeled clutch and brake sides. Now you can plug the new Front Speaker Output Harness onto your new speaker terminals. Route power/ground through fairing. Including installing rear speaker wires, feed the Rear Speaker Input / Output Harness through fairing towards the rear of the speaker.
5 – Routing Power Harness / Rear Speaker Harness
Pass the Power / Ground Harness and Rear Speaker Harness through the fairing and route next to the factory wiring harness. Routing the new wire harnesses along with the factory harness is recommended. Be sure to zip tie the harnesses together for a clean, tight fit. Due to the size wire for the Power / Ground Harness and Rear Speaker Harness, it is recommended to route the wiring under the gas tank along the top of the frame on the motorcycle.
Note: Refer to the motorcycle manufacturer owner’s manual for bike. instructions regarding gas tank removal.
Step 6 – Rear Speaker Installation
With the seat already removed, route the Rear Speaker Harness toward the rear of the motorcycle over the fender along the brake side of the motorcycle. Unplug factory speaker wires from the speaker and plug them directly into the Rear Speaker Input / Output Harness. These are labeled clutch and brake side.
