Memphis MJP1522 15" Dual 2-Ohm MOJO Pro Subwoofer

The Memphis MJP1522 is a 15-inch MOJO Pro component car subwoofer designed for systems that need substantial low-frequency output. Its dual 2-ohm voice-coil configuration provides wiring flexibility for compatible mono amplifiers. This model is intended for a custom enclosure and is not a powered or pre-loaded subwoofer.

Rated for 750 watts RMS and 1,500 watts peak power, the MJP1522 is suited to listeners building a high-output bass system. Its 87 dB sensitivity supports strong output when paired with an appropriately matched amplifier. The large 15-inch cone is designed to add impact and weight to music with demanding bass content.

Memphis uses DVVC Direct Vent Voice Coil Cooling and cross-drilled front-plate venting to help manage heat during sustained use. An aluminum shorting ring is incorporated to reduce inductance. These engineering details support controlled operation in high-SPL-focused installations.

The MJP1522 combines a rigid paper cone with a double-stitched foam surround and progressive spider. A die-cast basket provides a stable foundation for the moving assembly, while single-sided compression terminals simplify speaker-wire connections. The result is a purpose-built subwoofer architecture for custom vehicle audio systems.

This subwoofer is designed to fit more traditional enclosure applications, including sealed and vented designs. Memphis publishes gross-volume recommendations for single- and dual-subwoofer systems, allowing installers to select an enclosure approach based on available space and output goals. Allow for its 7.88-inch mounting depth and 13.84-inch cutout requirement before planning the installation.

Key Features

• 750W RMS Rating: Supports amplifier matching for sustained bass output.
• Dual 2-Ohm Voice Coils: Enables 1-ohm parallel or 4-ohm series wiring.
• DVVC Cooling: Vented voice-coil design helps manage operating heat.
• Aluminum Shorting Ring: Reduces inductance in the motor assembly.
• Rigid Paper Cone: Provides a durable cone structure for bass reproduction.
• Die-Cast Basket: Supplies a rigid platform for the driver assembly.

Design & Installation

The MJP1522 uses a 120-ounce magnet, 2.5-inch voice coil, rigid paper cone, double-stitched foam surround, progressive spider, and die-cast basket. Cross-drilled front-plate venting and direct voice-coil ventilation are part of its thermal-management design. Single-sided compression terminals provide the connection point for subwoofer wiring.

Install the MJP1522 in a properly designed sealed or vented enclosure, observing the published 13.84-inch cutout diameter and 7.88-inch mounting depth. For one subwoofer, Memphis recommends 2.6 cubic feet gross sealed or 4.4 cubic feet gross vented; use an amplifier and wiring configuration compatible with its dual 2-ohm coils. Professional installation is recommended when enclosure construction, system gain setting, or amplifier impedance matching is unfamiliar.
