Memphis Audio PRX1024 10" Selectable-Impedance Subwoofer

The Memphis Audio PRX1024 is a 10-inch component car subwoofer designed to add low-frequency output to a custom vehicle audio system. It handles 300 watts RMS and 600 watts peak, making it appropriate for systems built around a properly matched mono or multi-channel amplifier. Its selectable 2-ohm or 4-ohm impedance gives installers more flexibility when planning amplifier load and future system expansion.

This subwoofer is intended for listeners who want to build a dedicated bass system rather than rely on factory full-range speakers alone. Its 10-inch format can suit many trunk, hatch, and custom-enclosure applications while using less mounting area than a larger 12-inch or 15-inch driver. Selectable impedance can be useful when configuring one subwoofer now and considering a second matching subwoofer later.

The PRX1024 uses a black polypropylene cone and double-stitched butyl rubber surround for a durable moving assembly. A reinforced spider shoulder, woven tinsel leads, and an improved suspension and coil design support controlled operation during bass playback. Its 60-ounce magnet and 2-inch voice coil are paired with a high-temperature TIL voice coil former.

Memphis Audio equips this model with FLEX Selectable Impedance Technology, allowing the subwoofer to be configured for either 2-ohm or 4-ohm operation through its terminal arrangement. DVVC Direct Voice Coil Cooling Technology is used to help manage voice-coil heat during operation. This design focuses on installation flexibility without requiring a separate fixed-impedance version of the subwoofer.

The PRX1024 is a component subwoofer, so it should be installed in a compatible enclosure and powered by an external amplifier. Its 5.2-inch mounting depth and 9.25-inch cutout diameter should be checked against the planned enclosure before installation. Match amplifier output and final impedance carefully to the subwoofer's 300-watt RMS rating and the amplifier manufacturer's load requirements.

Key Features

• Selectable Impedance: Configure the subwoofer for 2-ohm or 4-ohm operation.
• 300-Watt RMS Handling: Supports amplifier matching for sustained bass playback.
• DVVC Cooling: Helps manage heat at the voice coil.
• Polypropylene Cone: Provides a durable cone surface for bass reproduction.
• Double-Stitched Surround: Supports the cone assembly during movement.
• Stamped Steel Frame: Provides a rigid mounting structure for installation.

Design & Installation

The PRX1024 combines a black polypropylene cone with a double-stitched butyl rubber surround, reinforced spider shoulder, woven tinsel leads, and a stamped steel frame. Its 2-inch voice coil uses a high-temperature TIL former, while the 60-ounce magnet and DVVC cooling system support its power-handling design. These construction details are intended for a dedicated automotive subwoofer installation.

Plan the enclosure and amplifier system before mounting the driver. Confirm that the enclosure provides at least a 9.25-inch cutout and more than 5.2 inches of mounting clearance, then configure the terminal for the desired 2-ohm or 4-ohm load before wiring. A suitable external amplifier, enclosure, power wiring, signal connection, and installation hardware are required for a complete system.
