Extreme Sound System – Deeper bass, greater pressure and massive sound for your Harley-Davidson

Extreme is the third step in Fullblast's four sound levels and is designed for Harley-Davidson owners who want significantly more bass, volume and sound pressure than both Core and Premium. Here you get a combination of powerful front and rear speakers - and a subwoofer that elevates the entire soundstage to a serious level.

The system is powered by a Hertz SPL 4x150W amplifier , which provides full control over both the Hertz SX165 NEO front speakers and the powerful Hertz SX690 NEO 6x9 rear speakers . The result is a sound that cuts through wind noise and delivers both detail and punch at all speeds.

The Precision Power HD13.SBW subwoofer , which mounts in the side bag, gives you deep, noticeable bass that no OEM system can match. The subwoofer adds a whole new dimension to your music, so you can both feel and hear it on the road.

Installation is made easy with the SADDLE TRAMP mounting plate , Plug & Play wiring harness (HD 2014–2024), FULL BLAST AR9813 adapter rings and a complete 6x9 speaker grille kit . All fit perfectly for Harley-Davidson Touring models from 1998–2023.

Extreme is for those who want a complete, powerful and bass-rich MC sound system - without going all the way to the Insane level.
