Rockford Fosgate P3SD4-10 10" Shallow DVC Subwoofer

The Rockford Fosgate P3SD4-10 is a 10-inch shallow-mount car subwoofer designed for vehicles where conventional subwoofers do not have enough mounting depth. Its 3.50-inch mounting depth helps make bass-system upgrades practical in space-conscious applications. Dual 4-ohm voice coils provide wiring flexibility for matching a compatible amplifier.

Rated for 300 watts RMS and 600 watts maximum power handling, this Punch P3S model is intended to add low-frequency output without requiring a deep enclosure. It is a suitable choice for trucks, compact cars, and custom installations with limited behind-panel or under-seat space. The 40-250 Hz frequency-response specification supports its role as a dedicated bass driver in a larger car-audio system.

The P3SD4-10 uses an anodized aluminum cone and dustcap with an M-Roll Santoprene surround. This combination is paired with a shallow motor assembly, dual linear spiders, and embedded 16 AWG tinsel leads. Its StampCast basket incorporates spider venting to support airflow around the motor structure.

Rockford Fosgate specifies this subwoofer for either sealed or vented enclosures, allowing the installation to be tailored to available space and system goals. A 0.5 cubic-foot sealed enclosure is the listed ideal recommendation, while a 1.0 cubic-foot vented enclosure is also specified. The subwoofer itself displaces 0.074 cubic feet, which should be considered during enclosure planning.

For a complete system, pair the P3SD4-10 with a compatible mono or multi-channel amplifier, appropriate enclosure, wiring, and crossover setup. Its dual 4-ohm coils can be wired to a 2-ohm or 8-ohm final load for one subwoofer, depending on the amplifier and wiring arrangement. The shallow format makes it especially useful when installation depth is the primary constraint.

Key Features

• Shallow-Mount Profile: A 3.50-inch mounting depth supports installations with limited clearance.
• Dual 4-Ohm Voice Coils: Provides series or parallel wiring options for amplifier matching.
• 300-Watt RMS Rating: Supports power handling appropriate for a dedicated bass channel.
• Anodized Aluminum Cone: Uses a rigid cone and matching aluminum dustcap.
• StampCast Vented Basket: Integrates spider venting to support motor airflow.
• Sealed Or Vented Compatible: Allows use in either recommended enclosure style.

Design & Installation

The P3SD4-10 combines a shallow motor assembly with a StampCast basket, anodized aluminum cone and dustcap, M-Roll Santoprene surround, and dual linear spiders. It also uses embedded 16 AWG tinsel leads and dual 10 AWG compression terminals. A diamond-cut cast-aluminum trim ring is included in the design, while a grille is optional.

Use a 9.06-inch cutout and allow at least 3.50 inches of mounting depth behind the mounting surface. Rockford Fosgate lists a 0.40-1.00 cubic-foot sealed enclosure range, with 0.5 cubic feet as the ideal sealed volume; its recommended vented design uses 1.0 cubic foot gross internal volume and one 4-by-12-inch port. When using a vented enclosure, a subsonic filter is recommended by the owner’s manual.
