Memphis MX600-6 6-Channel Powersports Amplifier

The Memphis MX600-6 is a compact six-channel powersports amplifier designed for systems where installation space is limited. It provides separate output groups for full-range speakers and subwoofer or additional speaker channels, helping build a complete multi-speaker system from one amplifier. Its IP66-rated construction suits side-by-sides, ATVs, motorcycles, and similar exposed applications.

This amplifier is intended for riders who need more usable system power than a source unit can provide. It delivers 50 watts RMS to channels 1-4 and 100 watts RMS to channels 5-6 at 4 ohms, with higher output available at 2 ohms. The staggered channel configuration supports flexible speaker-system planning without adding multiple amplifiers.

The MX600-6 is engineered for clear, controlled amplification across a 10 Hz to 20 kHz frequency response range. Independent variable crossover sections for channels 1/2, 3/4, and 5/6 let an installer direct bass, midrange, or full-range signals to appropriate speakers. High-pass, low-pass, and full-range settings make it practical for mixed speaker and subwoofer layouts.

Durability is a central part of the design. The amplifier uses a conformal-coated circuit board, sealed connectors, and a water-resistant top cover over its controls. These details help protect the amplifier in powersports environments where dust, moisture, and changing weather are common concerns.

The MX600-6 fits well into a staged audio upgrade, whether powering several compact speakers or combining full-range speakers with a bridged subwoofer channel. It accepts both RCA low-level and high-level speaker inputs for integration with a broad range of source units. A 4/6-input switch also allows the amplifier to be configured around the number of source channels available.

Key Features

• Six-Channel Layout: Supports multi-speaker systems from one compact amplifier.
• Staggered RMS Output: Provides 75 x 4 plus 150 x 2 watts at 2 ohms.
• IP66 Rating: Resists water and environmental exposure in powersports applications.
• Conformal-Coated Board: Adds protection for the internal electronics.
• Variable Crossovers: Helps match frequency ranges to connected speakers.
• High/Low Inputs: Connects with RCA or speaker-level source signals.

Design & Installation

The MX600-6 uses a compact chassis measuring 11.7 x 4.35 x 1.75 inches. Its sealed connectors, conformal-coated board, IP66-rated protection, and water-resistant cover over the top-mounted controls are designed for exposed powersports installations. The top-mounted layout keeps crossover, gain, and input-mode adjustments accessible after mounting.

Install the amplifier in a secure location with ventilation and avoid direct water contact where possible. Use a compatible source signal, correctly fused power wiring, and speaker loads no lower than 2 ohms stereo or 4 ohms bridged. Memphis specifies the MXA8GKIT amplifier kit for this model; verify channel configuration, polarity, and final speaker impedance before powering the system.
