Clean amplifier installation in 1998–2013 Harley Touring fairings — no cutting, no modifications to the factory loom
The Precision Power HD13.AWK is a complete amplifier installation and wiring kit for 1998–2013 Harley-Davidson® Touring motorcycles. It includes the amplifier bracket, plug-n-play T-harness, and 8-gauge power and ground wiring needed to mount the Precision Power MAA4.400 inside the fairing without modifying the factory wiring loom. CVO® and Boom Audio™ bypass plugs are included for models where the factory amplifier must be removed from the signal path.
Adding an external amplifier to a 1998–2013 Harley Touring should not require cutting the factory wiring loom. The HD13.AWK's T-harness plugs directly into the OEM radio wiring — signal in from the factory radio, speaker signal out, amplifier power connected — without a single splice. The bracket positions the MAA4.400 inside the fairing cavity where it stays accessible and clear of factory components. The result is a clean installation that integrates properly with the OEM system and can be reversed without damage to the factory wiring.
Who This Is For
Riders adding an external amplifier to a 1998–2013 Harley Touring system who want a clean, OEM-quality installation without cutting the factory loom. The HD13.AWK is designed and optimised for the Precision Power MAA4.400 and is part of the HD13 system alongside the HD13.52 fairing speakers and HD13.LVF lower fairing pods.
What This Is Best For
- No-cut factory integration — The T-harness connects directly to OEM radio wiring without modifying the factory loom. Signal in from the radio, speaker signal out to the speakers, amplifier connected — no splicing required.
- Clean fairing-mounted amplifier installation — The included bracket positions the MAA4.400 inside the fairing cavity, keeping it accessible for future servicing and clear of factory components and moving parts.
- CVO® and Boom Audio™ compatibility — Bypass plugs for CVO® and Boom Audio™-equipped models are included, handling the additional integration step required on bikes fitted with factory amplifiers.
- Complete HD13 front-stage builds — The HD13.AWK is the power delivery component in an HD13 front-stage system. Pair with the MAA4.400 amplifier, HD13.52 fairing speakers, and HD13.LVF lower fairing pods for a complete amplified front stage.
Amplifier not included. The HD13.AWK is a mounting and wiring kit only. It is designed for the Precision Power MAA4.400. Other compact amplifiers may be compatible for experienced installers but bracket and connector fit should be confirmed before ordering.
CVO® models. CVO® Touring models with Boom Audio™ amplifiers require the bypass plugs included in the kit. Some CVO® models with Harman/Kardon amplifiers require a different integration approach — confirm your CVO® model's amplifier brand before ordering.
Contact Motorcycle Audio Australia to confirm amplifier compatibility and discuss system requirements before ordering.
The Bottom Line
The HD13.AWK removes the most frustrating part of adding an amplifier to a pre-2014 Harley Touring — the wiring. The T-harness handles OEM integration without touching the factory loom, the bracket positions the MAA4.400 cleanly inside the fairing, and the 8-gauge power wiring handles the current delivery. Everything needed to do the job properly is in the box.

What's In The Kit
Amplifier mounting bracket. A precision-fit bracket designed to mount the Precision Power MAA4.400 inside the fairing cavity of compatible 1998–2013 Touring models. The bracket positions the amplifier securely while maintaining clearance for factory components and leaving the unit accessible for future servicing or adjustment.
Plug-n-play T-harness. The T-harness connects directly into the OEM radio wiring loom, providing the amplifier input signal from the factory radio's speaker outputs without cutting or splicing the factory wiring. Speaker output connectors route the amplified signal back to the fairing speaker positions. The harness includes high-level input and speaker output connectors matched to the MAA4.400's terminals.
8-gauge power and ground wiring with 60A inline fuse holder. An 8-gauge power wire with inline 60A fuse holder, and 8-gauge ground wire, provide the current delivery path for the MAA4.400. Pre-wired power and ground connectors are configured for the amplifier's power terminals. The 60A fuse holder protects the power wire run between the battery and the amplifier.
CVO® and Boom Audio™ bypass plugs. Bypass plugs for models where the factory Boom Audio™ amplifier must be removed from the signal path to integrate a replacement. Required on CVO® and Boom-equipped models where the standard T-harness connection alone is not sufficient.
