51KXMA15001

Marine Amplifier: The Kicker KXMA1500.1 (51KXMA15001) marine amplifier can provide up to 1500 watts (@ 1- or 2-Ohms) to a single output. Designed for the marine environment, the KXMA1500.1 features marine-grade speaker terminals, stainless-steel screws, conformal-coated circuit boards, and ABYC/NMMA-compliant power and ground connections.

Note: The Kicker KXMA1500.1 marine amplifier is not waterproof and should not be mounted where it will get wet.

Class D Amplification: The KXMA1500.1 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 (all rated @14.4V, < 1% THD+N):

• 750 watts RMS x 1 @ 4 Ohms
• 1500 watts RMS x 1 @ 2 Ohms
• 1500 watts RMS x 1 @ 1 Ohm

 Controls:

• Input Level: 2-position switch; select high (speaker-level) or low (line-level)
• Input Gain Control: continuously variable from 125mV to 5V with the input level switch set to low; 250mV to 40V with the input level switch set to high
• Crossover: a variable Low Pass with a 24dB/octave slope
• Frequency: a rotary control; continuously variable from 40Hz-160Hz
• KickEQ Bass Boost: three rotary controls let you select a Frequency between 20-80Hz; adjust the Bandwidth (Q) between 1-5; and Boost the selected signal from 1-6 dB.

Auto Turn-on: The amplifier has three methods of turning on via a 3-way switch: +12V, DC Offset, and Audio:

• +12V: The preferred method (+12V) 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.
• DC Offset: 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 (>3 volts) on the speaker-level inputs, the amplifier automatically turns on.
• Audio (Signal Sense): This method detects an incoming audio signal from your source unit (speaker-level) and automatically turns on the amp.

PRT LED: A red Protect LED can let you know if a problem arises.

• Flickering: A flickering PRT LED can indicate low-voltage from the battery, either from a low battery or a weak power/ground connection.
• On Solid: This can indicate Thermal Shutdown, if the amp gets too hot; Shorted speaker output; or Low Voltage, if the incoming power is not within the 10V-16V operating range.

Wire Connections: The KXMA1500.1 has screw-down terminals for the power, ground, turn-on (REM), and speaker outputs. The Power and Ground slots are 0.47" wide and the Remote and Speaker slots are 0.21" wide. 1/0 AWG power and ground wires are recommended (sold separately). The Power and Ground terminals are ABYC/NMMA compliant for marine installations.

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 1/0-gauge amplifier wiring kit and a 150-amp external fuse be used when installing the amplifier.

Input Signal: The KXMA1500.1 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 125mV-5V (low) or 250mV-10V (high).

Line Out: A pair of RCA Output jacks are provided as a "pass-thru" for the incoming signal, letting you run the signal out to additional amplifiers.

Remote Bass Level Control: The KXMA1500.1 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).
