Shallow 12-Inch Loaded Enclosure

The Rockford Fosgate R2S-1X12 is a sealed subwoofer enclosure built for car audio systems with limited mounting depth. It houses a 12-inch mica cone woofer rated at 250W RMS and 500W peak power. The 2-ohm impedance load suits mono amplifiers stable at that resistance. High-current binding posts accept up to 12 AWG wire for secure connection.

Upgrade From Factory Bass

This enclosure replaces weak factory subwoofers or adds bass where no sub exists, delivering 81 dB sensitivity from a compact sealed design. The jump is worth it when trunk space is tight but you still want controlled low-frequency output. The 5/8-inch MDF construction reduces panel resonance compared with thinner prefab boxes. CEA-2031 compliance confirms the power ratings are verified.

For Space-Constrained Builds

Buyers who need a ready-to-install shallow enclosure with a 2-ohm final load will fit this unit behind seats or in shallow cargo areas. The tapered depth of 3.25 to 5.25 inches allows placement where standard boxes cannot go. Shoppers who require ported output, higher sensitivity, or a different impedance load should look at other configurations.

Questions about this item

What are the exact dimensions of the R2S-1X12 enclosure so I can check boot space?

The sealed box measures 13.5 inches wide, 27.375 inches deep, 5.25 inches tall at the bottom and 3.25 inches at the top.

How do I wire the subwoofer to my amplifier using the binding posts?

Connect speaker wire up to 12 AWG to the high-current compression terminals; the single 2-ohm voice coil is already wired internally for a 2-ohm load.

When should I plan to recone the 12-inch mica woofer?

Recone only if the cone tears or the voice coil overheats; with 250 watts RMS handling and 81 dB sensitivity, normal use rarely requires it.
