Rockford Fosgate P2D2-10 10" Dual 2-Ohm Subwoofer

The Rockford Fosgate P2D2-10 is a 10-inch dual voice coil car subwoofer designed to add dedicated low-frequency output to an aftermarket audio system. Its dual 2-ohm voice coils give installers flexibility when planning the final amplifier load. It is intended for use with an external subwoofer amplifier and a properly built enclosure.

This model suits listeners who want a compact 10-inch woofer for a trunk, hatchback, SUV, or custom vehicle enclosure. With a 300-watt RMS power rating, it is sized for moderate-power bass systems rather than a high-power competition build. The P2D2-10 can be used in either sealed or vented box designs depending on available space and system goals.

The Kevlar fiber reinforced paper cone is paired with a rubber surround and a dual linear spider assembly. This combination is designed to support controlled cone movement while handling sustained bass playback. Its 84 dB sensitivity rating and 29-250 Hz frequency-response specification place it squarely in the sub-bass and bass range.

Rockford Fosgate equips the P2D2-10 with a high-temperature, four-layer voice coil, a spun-laced Nomex reinforcement collar, and integrated spider venting in the StampCast basket. The extended pole piece and bumped vented backplate provide clearance and ventilation around the motor structure. Dual 10-AWG nickel-plated compression terminals provide substantial speaker-wire connection points.

For a balanced upgrade path, pair this subwoofer with an amplifier selected for its final wired impedance and approximately its 300-watt RMS rating. A sealed enclosure uses less volume and follows the published 0.50-0.85 cubic-foot range, while the recommended vented design uses 1.40 cubic feet gross internal volume. The included decorative trim ring provides a finished appearance, and an optional grille insert can be added for cone protection.

Key Features

• 300-Watt RMS Rating: Supports amplifier matching around 300 watts of continuous power.
• Dual 2-Ohm Voice Coils: Provides wiring flexibility when configuring an amplifier load.
• Kevlar-Reinforced Paper Cone: Combines a paper-cone character with added fiber reinforcement.
• StampCast Vented Basket: Integrates spider venting to help manage voice-coil heat.
• VAST Cone Design: Increases effective cone area compared with conventional mounting designs.
• 10-AWG Compression Terminals: Accommodates larger speaker wire for secure connections.

Design & Installation

The P2D2-10 uses a Kevlar fiber reinforced paper cone, protective textured PVC magnet cover, dual linear spiders, and embedded 16-AWG tinsel leads. Its high-temperature voice coil uses a spun-laced Nomex reinforcement collar, while the extended pole piece and bumped vented backplate support the motor assembly. A diamond-cut cast aluminum trim ring is included, with an optional grille insert available separately.

Confirm a 9.13-inch cutout and at least 5.92 inches of mounting depth before installation. Use a sealed enclosure between 0.50 and 0.85 cubic feet, or follow the published 1.40-cubic-foot vented enclosure design with a 4-inch by 14-inch port. Match the amplifier to the final impedance created by the dual 2-ohm coils, and set gain carefully to avoid overpowering the 300-watt RMS-rated woofer.
