Soundigital SD-10 Harley 10" Subwoofer Adapter Rings (Pair) All Years 98-Current

Gear up your ride with these CNC-molded 10" Harley Subwoofer Adapter Rings—designed for riders who want deeper, clearer bass without sacrificing saddlebag space. This wheel-side mount adapter features an 11" outer diameter, a 9" inner diameter, a 5-bolt pattern, and a ½" mounting surface tilt to follow the bag’s contour for optimal airflow and venting.

Compatibility and install notes: fits Harley models 98–current; bag brands vary, and some trimming or minor modifications to the saddle bag may be required. The inside diameter may need a slight opening for different speaker manufacturers. Bonding panel not included; epoxy like 3M 08115 is recommended. CNC precision delivers a snug, durable fit—you may need to sand the mounting face or seal gaps with silicone caulk for best results. Custom logos are available (note: Harley logos will not be engraved). Sold in pairs; grills sold separately. For power and clarity, pair with a Soundigital SD-10 amp for clean, punchy output.

Why riders choose these rings: easier installation, deeper bass, and a professional, custom look that fits your Harley’s personality and bag setup.
