Aggressor Pro 100 Subwoofer Mount

Pro-Grade Bass: Aggressor Pro 100 Twin Sub Mount Kit

Built for big sound, not bulky compromises. The Aggressor Pro 100 Subwoofer Mount from American Hard Bag is the gold standard in Harley touring audio. This is the OG product that started it all—refined over 9 years and still unmatched. It’s the only sub mount kit that beefs up your saddlebag structure rather than cutting it down, while keeping most of your luggage space intact.

Engineered for maximum output, minimal intrusion. Unlike weaker kits that rattle your bags to bits, the Aggressor Pro 100 mounts reinforce your factory bags, giving you tighter bass, louder volume, and unbeatable rigidity. The smart design includes a high-flow stamped steel grill that lets your woofer breathe freely without muffling your sound or muddying your tone. And yes—this one’s waterproof and UV-stabilised for real-world Aussie conditions.

Pro-level fitment with everything you need. You’re not just getting a mount—you’re getting a complete system. CNC-machined templates, precision router bit, neoprene gasketing, hardware, grills—it’s all here. The mount fits woofers with a standard 8-bolt 246mm (9.7") bolt circle and allows for 12.7mm (½") cone excursion beyond the gasket surface. Designed specifically for efficient, lightweight woofers—not mega car subs. Maximum mounting depth is 120.6mm (4.75").

Flexible configuration to suit your build. Whether you want thunder from the left, punch from the right, or dual-bag devastation, the Aggressor Pro 100 is available for left, right, or twin bag installation. No matter the setup, your bag integrity stays rock solid, your bass stays clean, and your gear stays protected.

Designed to last. Built in the USA. This isn’t just another bolt-on gimmick. The Aggressor Pro 100 is machined from solid high-density polyethylene with stainless hardware and American-made steel grills. It’s backed by a serious 5-year warranty and installation support—because you’re not just buying a product, you’re joining a crew that takes audio as seriously as you do.
