This Kawassaki Brute force was outfitted with a Sony DSX-M60 headunit that commands a M700/5 5 channel marine amp powering three sets of MX650-CCX-CG-TB 6 1/2" marine coaxial and two M10W5-SG-TB 10" subwoofers. The front box is a standard ATVoomer box housing the amp visible thru a custom opening cut in the front and covered with a plexi window, along with two pairs of speakers and the radio while the rear box is a custom fiberglass replica of the front modified to house the 10" subs...bottom line: LOUD!!!!.....Thanks JL Audio!!!!...Other mods included an extra battery in a custom tray in the back, 13 ft. of LED tape along the under cariage, HID's and a custom front grille and digital cammo vinyl wrap.
