Top Sellers For Harley Davidson®

The most popular JVC, Diamond, Rockford Fosgate, and Soundqubed gear our Harley-Davidson® customers are actually buying. Whether you're upgrading your bagger's factory sound system or building a full custom motorcycle audio setup from scratch, these are the brands that deliver real performance on two wheels.

Head units with Apple CarPlay and Android Auto keep you connected without taking your eyes off the road. Weather-resistant speakers handle wind, rain, and heat without losing clarity. Amplifiers from Rockford Fosgate and Soundqubed push clean, stable power even at highway speeds.

Diamond Audio has become one of our top picks for Harley-Davidson® builds — their motorcycle-specific speaker lines drop into factory locations with minimal modification, delivering a massive upgrade without a massive install headache.

At 12 Volt Outlet, we stock the gear that experienced installers and dedicated riders have vetted in real-world conditions. Shop by brand or by category — and if you need help building out your system, we're here.
