KICKER 48KMA6006 600 Watt 6-Channel Marine Amplifier Boat Amp KMA600.6

The KMA600.6 is a six-channel Class D marine amplifier built around three independent zones. It delivers 100W per channel at 2 ohms, 50W per channel at 4 ohms, or 200W bridged into three channels, with 750W of dynamic power. With bridging, it can run as many as 12 speakers.

Three zones is the point here. Cockpit, bow and tower can each get their own level and crossover setting, so people sitting in the bow are not stuck with whatever the tower speakers are doing. Amps 1 and 2 use a variable 12dB high pass from 0 to 200Hz. Amp 3 adds selectable off, high pass or low pass from 50 to 200Hz, a fixed 25Hz subsonic filter and KickEQ variable bass boost up to 6dB centered at 40Hz, which makes it the natural choice for a subwoofer channel.

The board is conformal coated, power connections meet ABYC and NMMA standards, and 316L stainless-steel mounting hardware is included. Frequency response spans 10Hz to 20kHz with signal-to-noise above 95dB.

At 2-5/16" tall, 7-1/8" wide and 13-15/16" long, one chassis replaces the two or three amplifiers a zoned system would otherwise require, freeing up locker space on pontoons, deck boats and wake boats.
