Thunder Mountain Audio — Motorcycle Speaker Systems
Thunder Mountain Audio is an independent American manufacturer of universal, highway-rated motorcycle speaker systems. Our kits clamp to any 7/8-inch to 1.25-inch handlebar or highway bar without drilling, and are engineered to stay clear at 80+ MPH on cruisers, touring bikes and naked motorcycles.
Every Thunder Mountain Audio system is assembled, bench-tested and supported in Colorado, USA, uses weather-sealed amplifiers and marine-certified drivers, and is covered by a 3-Year Standard Guarantee.
Motorcycle speaker kits
Shipping, returns & warranty
Every kit is assembled and bench-tested to order in Colorado, then shipped by FedEx Ground with full value insurance and signature confirmation. Build time is 3–5 days before your kit ships to the contiguous United States; transit time after that belongs to the carrier, so no arrival date is promised. Returns are accepted within 30 days of the carrier delivery scan with a 10% restocking fee, provided the kit is in good condition with original packaging. A 3-Year Standard Guarantee is included on every system, with an optional 5-Year Legacy Protection extension.
