Features

Marine-Ready: The Kicker KM series KM604WL (51KM604WL) marine coaxial speakers are engineered to meet or exceed ASTM B117 Salt Fog (200 hour test) and ASTM G154 Accelerated UV (400 hour test) industry standards. The speakers feature sealed motors and cones, and are housed in UV-resistant polymer baskets and frames. Each speaker also features a non-removable spoke-style polymer grille (white).

RGB LEDs: There are multi colored LEDs behind the tweeter casing, to create a glow on the woofer cone. Depending on what combination of the three LED wires is connected, they can light red, green, blue, lime green, magenta, aquamarine (cyan), or blue-white. A wireless remote (item number 20641KMLC, sold separately) is also available to control the backlighting. A 12 volt power supply is needed to turn the LEDs on.

Free-Air Mounting: The KM604WLs can be free-air mounted and do not require a sealed air space. The speakers require a 5.154" (approximately 5-5/32") cutout and 2.573" of mounting depth. Stainless steel mounting hardware is included.

Terminals: The speakers feature slip-on terminals (0.250" & 0.187") for attaching your speaker wire.
