48KMA1502

Marine Amplifier: The Kicker KMA150.2 (48KMA1502) 2-channel amplifier can provide 65 watts x 2 (4Ω). Both channels can also be bridged for a single 150 watt x 1 output (4Ω). Designed for the marine environment, the KMA150.2 features marine-grade speaker terminals, stainless-steel screws, conformal-coated circuit boards, and ABYC/NMMA-compliant power and ground connections.

Note: The Kicker KMA150.2 marine amplifier is not waterproof and should not be mounted where it will get wet.

Class AB Amplification: The KMA150.2 features state-of-the-art Class AB amplification which provides ample power in a compact chassis. The 4-channel amp can provide the following power output:

• 40 watts RMS x 4 @ 4 Ohms (@14.4V, ≤ 1% THD+N)
• 75 watts RMS x 4 @ 2 Ohms (@14.4V, ≤ 1% THD+N)
• 150 watts RMS x 2 @ 4 Ohms bridged (@14.4V, ≤ 1% THD+N)

 Controls:

• Input Level: 2-position switch; select high (speaker-level) or low (line-level)
• Input Gain Control: continuously variable from 250mV to 10V with the input level switch set to low; 1V to 40V with the input level switch set to high
• Crossover: 3-position switch; select Off, High Pass, or Low Pass; the slope is 12dB/octave for both
• Frequency: a rotary control; continuously variable from 50Hz-200Hz
• Bass Boost: a rotary control lets you increase the bass level between 0dB and +6dB; centered at 40Hz

Auto Turn-on: The amplifier has two methods of turning on: +12V and DC Offset. The preferred method is to run an 18-gauge wire from the remote turn-on lead of the source unit to the Remote (REM) terminal on the amp. When a +12V signal is detected on the wire, the amplifier will turn on. If your source unit lacks a remote turn-on lead (a factory head unit, for example), you can choose to turn on the amplifier via the DC Offset method. When a DC offset is detected (>2.5 volts) on the speaker-level inputs, the amplifier automatically turns on.

Wire Connections: The KMA150.2 has screw-down terminals for the power, ground, turn-on (REM), and speaker outputs. The power and ground slots are 0.512" wide and the remote and speaker slots are 0.335" wide. 8 AWG power and ground wires are recommended (sold separately).

External Fuse: The amplifier does not include a built-in fuse, therefore an external fuse should be placed on the power wire, within 18" of the battery. It is recommended that an 8-gauge amplifier wiring kit and a 40-amp external fuse be used when installing the amplifier.

Note: Currently Kicker will extend the standard warranty by an additional year (for a total of three years) when a qualifying Kicker Installation Kit is purchased with the amplifier.

Input Signal: The KMA150.2 accepts either high (speaker-level) or low (line-level) input signals on the single pair of RCA inputs, selectable using the input level switch on the end of the amp. When using a speaker-level input signal, add the optional Kicker KiSL speaker-level to RCA adapter. The input sensitivity is 250mV-10V (low) or 1V-40V (high).
