Rockford Fosgate R2S-1X12 12" Shallow Loaded Subwoofer

The Rockford Fosgate R2S-1X12 is a sealed, single-12-inch shallow loaded subwoofer enclosure designed for vehicles where conventional subwoofer boxes take up too much room. Its low-profile wedge shape is intended for tight locations such as behind the seat in many single-cab trucks. The enclosure arrives with the subwoofer installed and internally wired, simplifying the path to adding bass to a compatible system.

This enclosure is suited to listeners who want additional low-frequency output without committing much cabin space to a deeper box. The sealed design is built around a Rockford Fosgate R2SD4-12 shallow dual-voice-coil subwoofer and presents a 2-ohm nominal load. With 250 watts RMS power handling, it is intended to pair with an amplifier rated appropriately for a 2-ohm subwoofer load.

The R2S-1X12 emphasizes a compact installation footprint while retaining a full 12-inch woofer. Its wedge enclosure measures just 3.25 inches deep at the top and 5.25 inches deep at the bottom, helping it fit where seat travel and rear-cab clearance are limited. This makes it a practical option when a traditional full-depth enclosure will not fit.

The installed R2SD4-12 uses a shallow-profile motor and frame design, a polypropylene cone, foam surround, and dual 4-ohm voice coils. Inside this loaded enclosure, the voice coils are wired to a 2-ohm nominal impedance. The result is a ready-to-connect passive bass enclosure that can be integrated with an aftermarket amplifier and source unit.

Construction includes 5/8-inch MDF, high-density carpet covering, and quick-release compression terminals. Mounting brackets and self-tapping screws are included to help secure the enclosure in an appropriate vehicle location. It is a focused upgrade for space-constrained installations that need a compact, enclosed subwoofer solution.

Key Features

• 12-Inch Shallow Subwoofer: Provides bass reinforcement in a space-conscious enclosure.
• Sealed Wedge Enclosure: Fits low-clearance locations with limited available depth.
• 2-Ohm Nominal Load: Internally wired for a compatible 2-ohm amplifier connection.
• 250-Watt RMS Handling: Matches amplifiers delivering appropriately rated continuous power.
• 5/8-Inch MDF Construction: Provides a solid enclosure foundation for the installed woofer.
• Quick-Release Terminals: Makes connecting speaker wire more straightforward during installation.

Design & Installation

The R2S-1X12 uses a sealed wedge enclosure constructed from 5/8-inch MDF and finished in high-density carpet. Its angled profile measures 13.5 inches high and 27.375 inches wide, with a 5.25-inch bottom depth and a 3.25-inch top depth. The enclosure uses quick-release compression terminals for its speaker-wire connection.

Install the enclosure only after measuring the intended location and allowing room for seat movement, wiring, and secure mounting. Connect it to an external amplifier that is stable at a 2-ohm load and whose RMS output is matched appropriately to the enclosure's 250-watt RMS rating. Two mounting brackets and four 3/4-inch self-tapping screws are included to assist with securing the enclosure.
