Bazooka MA275D 75W x 2 Marine Amplifier

This sleek Class D marine amp offers a very low profile for easy installation.

Plenty of sound, plus room to grow

The MA275D 2-channel amp delivers the power you need to drive a pair of full-range speakers in your boat, sending 75 watts continuous power to each speaker. You can also bridge the amp to single-channel mode to deliver 225 watts to a marine subwoofer. This rugged amp features both high-pass and low-pass filters, so you can adjust the output to suit your system.

Bazooka's designers know what boaters want from an amplifier, so they designed this amp to be compact, cool, efficient, and powerful. You can mount the MA275D in a storage locker, console, or other tight spot without sacrificing space you'd rather use for extra lines, life jackets, and other boating gear.

Features

Overview: The Bazooka MA275D is a 2-channel Class D marine amplifier. It comes with a Remote Bass Controller to let you adjust the volume from the driver's seat or from the cabin of your vessel. Also included are mounting brackets and stainless steel hardware.

  • 75 watts RMS x 2 channels at 4 ohms
  • 100 watts RMS x 2 channels at 2 ohms
  • 170 watts RMS x 1 channel at 4 ohms bridged

Controls: The MA275D's controls are conveniently located on one side for easy access. The controls include:

  • Input Level: The rotary Input Level control lets you match the amplifier with the strength of the input signal from the source unit. The range is 0.2V to 6.0V. The control can be adjusted by hand, or with a small screwdriver (not included).
  • Crossover: The built-in crossover is adjustable from 50Hz to 500Hz. You can set the crossover mode to low-pass, high-pass, or flat. The frequency knob can be adjusted by hand or with a small screwdriver.

Remote Bass Control: The amp has an RJ25 jack for connecting the supplied Remote Bass Control. The gain of the amplifier can be adjusted remotely from 0.2V to 6V using the remote knob. The Remote Bass Control module can be installed in the driver's seat of your vehicle, or at the helm or in the cabin of your vessel. The attached cable is 12.5 feet in length.

The speaker terminals will accept up to 10 AWG wire. All of the set screw terminals can be tightened/loosened with a flat head or Phillips head screwdriver (not supplied). A 20A fuse should be installed on the power wire with 18" of the battery. A pair of RCA jacks is provided for connecting the input signal cable from the source unit. In addition, a speaker-level input harness is included, which plugs into the side of the amp via a Molex plug. Two speaker outputs from the source unit should be spliced into the harness.
