Precision Power HD13.SBW | Harley Davidson® ‘98-‘13 300W Class-D Subwoofer Amplifier

Precision Power HD13.SBW – 300W Saddlebag Subwoofer Amplifier Kit for 1998–2013 Harley-Davidson® Touring Models

The Precision Power HD13.SBW is a plug-and-play powered subwoofer system designed for 1998–2013 Harley-Davidson® Touring motorcycles. Featuring a custom down-firing subwoofer, built-in 300W Class-D amplifier, and rugged ABS enclosure, it delivers deep bass without compromising saddlebag space or structure.

• [ALL-IN-ONE POWERED SUBWOOFER SOLUTION FOR TOURING MODELS] This saddlebag subwoofer kit combines an integrated Class-D amplifier, custom subwoofer, and passive radiator in a single enclosure. It’s engineered to fit seamlessly into factory bags with no structural modifications, offering loud, clean bass for any ride.
• [BUILT-IN 300W CLASS-D AMPLIFIER WITH FAULT PROTECTION] The onboard 300W digital amplifier uses Class-D efficiency to deliver strong low-frequency output with minimal heat and power draw. Built-in fault protection circuitry ensures long-term performance, even in extreme riding conditions.
• [PASSIVE RADIATOR DESIGN FOR BOOSTED BASS RESPONSE] A low-frequency passive radiator complements the active subwoofer, enhancing low-end output without needing a ported enclosure. The neodymium magnet motor provides high SPL in a lightweight format—ideal for motorcycle applications.
• [WATER-RESISTANT, RUGGED CONSTRUCTION WITH MEMBRANE PORTING] Constructed from rotational-molded ABS, the enclosure resists vibration, water, and UV damage. A hydrophobic grommet membrane allows bass to exit the saddlebag while blocking dust and moisture, using the same waterproofing technology found in sport earbuds.
• [PLUG-N-PLAY INSTALLATION FOR OE & AFTERMARKET HEAD UNITS] This kit includes waterproof quick-disconnect wiring and a pre-configured harness for easy connection to stock Harley-Davidson® radios or aftermarket units with Apple CarPlay® and Android Auto®. Adjustable input switches support both high- and low-level signals.

The Precision Power HD13.SBW is the ultimate subwoofer upgrade for Harley riders who want deep, impactful bass without the complexity of custom audio builds. It's powerful, weather-ready, and purpose-built for Touring bikes.
