The Wet Sounds HTM-4 Compact IPX5 Full-Range Class-D 4-Channel Amplifier (MPN: HTM-4 | UPC: 810042177833) is engineered specifically for extreme tight-clearance installations—delivering 85W x 4 RMS @ 4Ω, 150W x 4 RMS @ 2Ω, and 300W x 2 RMS bridged @ 4Ω (600W total RMS) from a fairing-ready 8.83" W x 5.80" D x 2.35" H IPX5 water-resistant chassis.

With a reduced 2.35-inch height compared to legacy HTX amplifiers, the HTM-4 tucks seamlessly inside Harley-Davidson Street Glide and Road Glide fairings, Polaris RZR / Can-Am Maverick X3 dashes, Jeep Wrangler panels, and compact center-console boats. Selectable Full / HP / LP crossovers (50Hz–500Hz), a dedicated 10Hz–55Hz subsonic filter on Channels 3/4, removable terminal plugs, and a reversible blue LED badge make custom rigging effortless.
