Insane Sound System – Ultimate power, dual subwoofer and extreme sound for your Harley

Insane is the highest level in Fullblast's sound hierarchy - the system for those who want absolute maximum power, depth and sound pressure. Here you get a setup that surpasses Core, Premium and Extreme incomparably and delivers a sound universe that can be felt throughout the body, even at high speed.

The system is based on a Hertz SPL 4x150W amplifier , which drives both the Hertz SX165 NEO front speakers and the solid Hertz SX690 NEO 6x9 rear speakers . It gives you a wide, detailed and powerful sound image that stands out regardless of road, speed and wind conditions.

What makes Insane truly unique are the two Precision Power subwoofers – HD13.SBW (left case) + HD13.SBWR (right case) . With subwoofers in both side cases , you get twice the bass, deeper response and a sound experience that is in a class of its own. The music is not just heard – it is physically felt.

Installation and fitment are made simple with the SADDLE TRAMP amplifier plate , Plug & Play wiring harness (HD 2014–2024), FULL BLAST AR9813 adapter rings and a complete 6x9 speaker grille kit for Harley-Davidson Touring 1998–2023. Everything is designed to fit directly on the Harley, so the installation is stable, clean and strong.

Insane is for those who want the absolute wildest MC sound system – without compromise, without limitations and with maximum bass and volume.
