Memphis MJ1512 MOJO 15" Selectable-Impedance Subwoofer

The Memphis MJ1512 is a 15-inch MOJO-series car audio subwoofer designed for systems that need substantial low-frequency output. It is rated for 2000 watts RMS and 4000 watts peak power handling. Its FLEX selectable-impedance system allows the subwoofer to be configured for either a 1-ohm or 2-ohm load.

This model suits enthusiasts building a dedicated bass system with an appropriately matched mono amplifier and custom enclosure. The selectable impedance gives installers flexibility when planning amplifier compatibility and future system changes. It is a component subwoofer, so an enclosure, amplifier, wiring, and installation hardware are required separately.

The MJ1512 uses a high-excursion suspension system intended to move significant air while maintaining cone control. Memphis specifies 1 inch of XMAX and up to 1.75 inches of mechanical excursion. Its 86 dB sensitivity rating is listed at both selectable impedance settings.

A 300-ounce magnet structure and 4-inch aluminum triple voice coil support the subwoofer's high-power design. The vented cast-aluminum basket and DVVC direct vent voice coil cooling system are designed to help manage heat during demanding playback. A reinforced spider suspension helps support controlled cone movement.

The MJ1512 is intended for installations with enough room for a large 15-inch driver and a properly designed enclosure. Its 13.81-inch cutout diameter and 9.06-inch mounting depth should be confirmed before building or selecting a box. The included jumper plug is used to choose the 1-ohm or 2-ohm impedance configuration without complex voice-coil wiring.

Key Features

• 2000W RMS Handling: Supports high-power bass systems when paired with a properly matched amplifier.
• FLEX Selectable Impedance: Choose a 1-ohm or 2-ohm load using the included jumper plug.
• 4-Inch Aluminum Triple Voice Coil: Provides a substantial thermal platform for high-power operation.
• 300-Ounce Magnet Structure: Supports the motor strength required for a large-excursion subwoofer.
• High-Roll Surround: Enables 1 inch XMAX and up to 1.75 inches mechanical excursion.
• DVVC Cooling: Direct vent voice coil cooling helps manage heat during extended playback.

Design & Installation

The MJ1512 combines an orange cast-aluminum basket with a vented basket structure, reinforced spider suspension, and a high-gloss carbon-fiber dust cap. Its 4-inch aluminum triple voice coil and 300-ounce magnet are part of a motor assembly built for its 2000-watt RMS rating. The high-roll surround accommodates the driver's specified long-excursion capability.

Plan the enclosure around the required 13.81-inch cutout diameter and 9.06-inch mounting depth, while allowing adequate rear clearance and ventilation. Set the included FLEX jumper for either 1 ohm or 2 ohms before connecting the driver to an amplifier compatible with that load. Use an amplifier and enclosure appropriate for the subwoofer's 2000-watt RMS rating, and have the system professionally installed or tuned when needed.
