48KMA8001

Marine Amplifier: The Kicker KMA800.1 (48KMA8001) marine amplifier can provide up to 800 watts to a single output (1Ω). Designed for the marine environment, the KMA800.1 features marine-grade speaker terminals, stainless-steel screws, conformal-coated circuit boards, and ABYC/NMMA-compliant power and ground connections.

Note: The Kicker KMA800.1 marine amplifier is not waterproof and should not be mounted where it will get wet.

Class D Amplification: The KMA800.1 features state-of-the-art Class D amplification which provides ample power in a compact chassis. The mono amp can provide the following power output:

• 300 watts RMS x 1 @ 4 Ohms (@14.4V, ≤ 1% THD+N)
• 600 watts RMS x 1 @ 2 Ohms (@14.4V, ≤ 1% THD+N)
• 800 watts RMS x 1 @ 1 Ohm (@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: a variable Low Pass with a 12dB/octave slope
• 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 KMA800.1 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. 4 AWG power and ground wires are recommended (sold separately). Two sets of mono speaker terminals are provided for connecting more than one subwoofer.

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 a 4-gauge amplifier wiring kit and a 100-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 KMA800.1 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).

Remote Bass Level Control: The KMA800.1 amplifier includes a KMBLC Remote Bass Level control for adjusting the output level from the front seat. The Remote Bass Level Control can be mounted under a dash or console and includes a 19.5' remote cable (RJ-11 connectors on both ends).
