Product Research

Features

Overview: The Memphis Xtreme Audio MXA2.140 is a full range Class D MXA-series 2-channel amplifier for your vehicle, ATV, or boat. The amp features stainless-steel and aluminum hardware, and coated circuit boards, making it water-resistant and UV-resistant in extreme environments.

Output Power: The MXA2.140 outputs 100 watts RMS x 2 channels at 4Ω, 140 watts RMS x 2 channels at 2Ω. The amplifier cannot be bridged.

Controls: The amplifier features rubber covers over the controls to protect them from the elements. The rotary gain control can be adjusted with a flat-head screwdriver (not included). The amp has a 3-way switch for the crossover for selecting Low Pass (LPF), Full Range (FULL), or High Pass (HPF). A set of DIP switches lets you determine the cutoff frequencies for the crossover type you have selected: 50Hz or 250Hz for low pass and 80Hz or 120Hz for high pass.

Connections: The MXA2.140 has input connections coming from one end of the amplifier, and the power and speaker output connections coming from the other end. These connections are sealed to protect them from the elements, and have 4"-6" pigtails for connecting the supplied harnesses:

  • Inputs: The amp input can be line-level or speaker-level, and has a 4-pin Molex receptacle for connecting one of the supplied input harnesses. The line-level input harness has one pair of RCA jacks for connecting the source unit via an RCA cable. The speaker-level input harness has 4 wires for splicing to the source unit's speaker wires.
  • Power: The 12" power harness has power, ground, and remote turn-on wires. The power wire has an in-line 25A ATM (mini-blade) fuse installed. The power harness has a 3-pin Molex plug.
  • Speaker Output: The speaker output harness has a 4-pin Molex plug and 4 speaker wires with left + (white), left - (white/black), right + (gray), and right - (gray/black) color coding.

Mounting: The MXA2.140 can be mounted in the hatch or trunk, or under the seat of a vehicle. Under the seat of a boat or ATV is also acceptable. It should be mounted in a location that avoids direct contact with water. The amp can be installed horizontally or vertically. Two sets of screws are included with the amplifier. Self-tapping screws can attach the amp to a wooden mounting board. The supplied stainless steel screws can be used with the amp's threaded mounting tabs to attach the amp to non-wooden surfaces.

Q
Can my mxa Bluetooth the music from my phone or do I need to have a head unit?
[ Johnathan  Oct 18, 2017 ]
1 answer
A
The amplifier does not have built-in Bluetooth so, you will need an external device to provide this capability; it does not have to be a head unit though.
