Memphis MX150.2-24V 2-Channel 24V Powersports Amplifier

The Memphis MX150.2-24V is a compact two-channel powersports amplifier designed for vehicles that use an 8V to 24V DC electrical system. It is a practical option for golf carts and other equipment operating on 24V power where a conventional 12V amplifier may not be suitable. Its small footprint helps add amplified sound where mounting space is limited.

Rated at 75 watts RMS per channel at 2 ohms, this amplifier is intended to drive a pair of compatible speakers in a compact audio system. Its published 60Hz to 20kHz frequency response supports clear playback across the main listening range for speaker-based upgrades. The two-channel layout suits simple front-speaker, pod-speaker, or compact powersports installations.

The MX150.2-24V uses a sealed harness and sealed gain controls to support use in exposed powersports environments. It carries an IP66 rating and uses a textured black heatsink with injection-molded end plates. Memphis notes that the amplifier is water resistant, but it should not be mounted where it can be submerged.

Low-level source input is supported, and the wiring diagram also shows use with a high-to-low converter when connecting to an appropriate source. The input range is specified at 450mV to 4.5V, allowing gain adjustment for compatible signal sources. A 20A fuse is shown in the supplied wiring diagram for circuit protection.

This amplifier fits a straightforward two-speaker upgrade path for a golf cart, side-by-side, motorcycle, marine application, or another compact vehicle using a compatible electrical system. It is not specified for bridged operation or 1-ohm loads. Memphis lists its 10GKIT amplifier kit as the recommended connection kit.

Key Features

• 8V-24V DC Operation: Supports a broad vehicle-voltage range, including 24V golf-cart systems.
• Two-Channel Output: Provides 75 watts RMS per channel at 2 ohms.
• IP66 Rating: Adds water and dust resistance for exposed powersports use.
• Sealed Controls And Harness: Helps protect adjustment and wiring connection areas.
• Ultra-Compact Chassis: Fits installations with limited available mounting space.
• 20A Fusing: The wiring diagram specifies a 20A fused power connection.

Design & Installation

The MX150.2-24V combines a black textured heatsink with injection-molded end plates in a compact 4.8 x 3.2 x 1.5-inch housing. Its sealed gain pots and harness complement the IP66-rated design for applications exposed to weather, dust, and vibration. Memphis also identifies the amplifier as using a top-mounted control panel.

Mount the amplifier in a location that remains dry and is not subject to submersion. Use the yellow power lead, black ground lead, and blue remote lead as shown in the wiring diagram, with a 20A fuse installed near the battery connection. Verify the speaker load before connection, use compatible 2-ohm speakers for the published power rating, and use a high-to-low converter when the source does not provide a suitable low-level signal.
