Memphis MJP2000.1 2000W RMS Mono Subwoofer Amplifier

The Memphis MJP2000.1 is a mono subwoofer amplifier built for high-output car audio systems that need dedicated low-frequency power. It delivers a rated 2000 watts RMS through one channel at 1 ohm, with additional power ratings for 2-ohm and 4-ohm subwoofer loads. It is suited to systems where the subwoofer or subwoofer array is wired to a compatible final impedance.

Designed as part of Memphis Audio's MOJO Pro series, the MJP2000.1 provides focused bass amplification without requiring a multi-channel amplifier to handle the low end. Its 11Hz-200Hz frequency response and variable crossover controls support integration with a separate full-range speaker amplifier. A variable subsonic filter and variable EQ bass boost provide additional tuning tools for subwoofer systems.

The amplifier uses 12dB-per-octave Butterworth crossovers to help shape the bass range sent to connected subwoofers. Its input range of 400mV to 7.5V accommodates a range of source-unit and signal-processor output levels. Total harmonic distortion is rated below 1% at 4 ohms, and the signal-to-noise ratio is rated at 80dB.

An extruded aluminum heatsink forms the amplifier chassis and is designed to manage heat during sustained operation. Exposed aluminum accents and the MOJO orange accent strip give the amplifier its distinctive series appearance. The compact 2-inch-tall chassis can be useful where mounting height is limited, while its 13.2-inch length should be considered during layout planning.

The MJP2000.1 can be strapped with another compatible mono amplifier for expanded-system applications. A wired bass knob is included for convenient level adjustment from the driver's seat. Memphis recommends its 0GKIT installation kit, making this amplifier appropriate for professionally planned high-current subwoofer upgrades.

Key Features

• 2000W RMS Mono Output: Delivers one-channel RMS power at a 1-ohm load for compatible subwoofer systems.
• Three Rated Load Outputs: Provides rated RMS output at 4 ohms, 2 ohms, and 1 ohm for flexible subwoofer wiring plans.
• 12dB Butterworth Crossovers: Helps tailor the amplifier's low-frequency output to the rest of the audio system.
• Variable Bass Controls: Includes variable crossover, subsonic-filter, and EQ bass-boost adjustment for system tuning.
• Strappable Mono Design: Allows compatible mono amplifiers to be linked in larger installations.
• Included Bass Knob: Provides wired remote adjustment of bass level from the listening position.

Design & Installation

The MJP2000.1 uses an extruded aluminum heatsink chassis with exposed aluminum details and a MOJO orange accent strip. This construction supports heat dissipation while giving the amplifier a durable, installation-focused exterior. Its dimensions are 7.5 inches wide, 13.2 inches long, and 2 inches high.

Plan the subwoofer wiring so the final load matches one of the amplifier's rated 1-ohm, 2-ohm, or 4-ohm configurations. Allow clearance for wiring, ventilation, and access to the gain and tuning controls, and use appropriately sized power wiring; Memphis lists the 0GKIT as the recommended installation kit. For a strapped setup, follow the applicable Memphis installation instructions and use a compatible paired mono amplifier configuration.
