Memphis VIV1012 10" FLEX Selectable-Impedance Subwoofer

The Memphis VIV1012 is a 10-inch car audio subwoofer designed for systems that need substantial bass output while retaining flexibility during amplifier selection. Its 1000-watt RMS power rating makes it appropriate for dedicated mono-amplifier subwoofer stages. The compact 10-inch format is suited to installations where a larger woofer is not practical.

This model uses Memphis Dual FLEX Technology to select either a 1-ohm or 2-ohm impedance configuration. The change is made with the FLEX jumper plug rather than conventional coil rewiring. That gives installers a direct way to match the subwoofer's load setting to a compatible amplifier.

The VIV1012 is built around a 3.3-inch aluminum voice coil and a 162-ounce magnet motor. DVVC direct-vent voice-coil cooling is used to help manage thermal buildup during high-power operation. This combination supports its 1000-watt RMS and 2000-watt peak power-handling ratings.

A folded V-Groove surround is part of the woofer's excursion-focused design. It is intended to support greater cone travel while preserving effective cone surface area. The result is a subwoofer platform designed to move air efficiently in a properly designed enclosure.

For a complete system, pair the VIV1012 with a compatible amplifier that is stable at the selected 1-ohm or 2-ohm setting and appropriately rated for the subwoofer's continuous power capacity. It requires a suitable enclosure, amplifier wiring, and signal source, none of which are specified as included. Confirm enclosure design, available mounting clearance, and amplifier load capability before installation.

Key Features

• 1000W RMS Handling: Supports a substantial continuous-power subwoofer stage.
• FLEX Impedance Selection: Choose 1-ohm or 2-ohm operation using the jumper.
• 3.3-Inch Aluminum Voice Coil: Provides a large-format motor component for power handling.
• DVVC Cooling: Direct venting helps manage voice-coil heat.
• Folded V-Groove Surround: Supports excursion while preserving effective cone area.
• 162-Ounce Magnet: Supplies a substantial motor structure for the woofer.

Design & Installation

The VIV1012 combines a 162-ounce magnet motor with a 3.3-inch aluminum voice coil, DVVC cooling, and a folded V-Groove surround. Its multi-voice-coil FLEX arrangement provides selectable 1-ohm or 2-ohm operation. The published sensitivity is 85.5 dB at 1 ohm and 84.8 dB at 2 ohms.

Allow at least 6.57 inches of mounting depth and prepare a 9.25-inch cutout where appropriate for the enclosure. Select the impedance setting with the FLEX jumper plug before connecting the subwoofer to the amplifier, and use an amplifier rated for the selected load. Installation should account for enclosure requirements, secure mounting, and adequate amplifier power and wiring.
