Ready-to-install 12-inch subwoofer enclosure

The Rockford Fosgate P1-1X12 is a pre-loaded vented enclosure housing a single 12-inch Punch P1 woofer with a Kevlar cone. It arrives fully assembled and internally wired to present a 4-ohm load to the amplifier. The cabinet is built from 5/8-inch MDF and wrapped in high-density carpet for durability.

Suits drivers wanting a single finished box

This enclosure fits buyers who want immediate bass output without designing or building a cabinet themselves. The quick-release compression terminals accept up to 10 AWG wire for fast installation. It is not suited for systems requiring multiple woofers, sealed alignment, or a different impedance load.

250 watts RMS power handling

The P1S4-12 woofer is rated for 250 watts continuous and 500 watts peak power with 86 dB sensitivity. Matching the amplifier to this RMS figure ensures clean output and long-term reliability. The 4-ohm nominal impedance determines which amplifiers can drive the enclosure safely.

Questions about this item

How can I verify the subwoofer is performing correctly after wiring it to my amplifier?

Set the amplifier gain so the 4-ohm load receives no more than 250 watts RMS; the 86 dB sensitivity means moderate volume at low power, and the proprietary high-flow low-noise port should produce clean bass without port chuffing at rated levels.

What components are included in the box and what must I purchase separately to install it?

The box contains the vented 12-inch Kevlar-cone woofer pre-mounted in a 5/8-inch MDF enclosure with high-current compression terminals accepting up to 10 AWG wire; you must supply an amplifier, power and ground wiring, a signal cable and a fused power kit.

Which version of this enclosure should I choose if my amplifier is stable at 4 ohms and rated around 250 watts RMS?

This single 12-inch Punch P1 model is internally wired to present a 4-ohm load and handles 250 watts RMS continuously, matching an amplifier with the same 4-ohm RMS rating for optimal performance.
