Rockford Fosgate P3-1X12 12" Ported Loaded Enclosure, 600 Watts Rms - The P3-1X12 is a single P3 12” vented enclosure with 600 Watts RMS power handling wired to a 1-Ohm load. The enclosure is constructed with 5/8” MDF, covered in high density carpet, and features quick release compression terminals. The most convenient way to get low frequency bass in your system is to drop-in a Punch Loaded enclosure. We're not talking junk in the trunk, we're talking the same genuine Punch woofers available separately. Punch Loaded enclosures are constructed with durable 5/8" MDF and tuned by our computer aided design software. P3 Loaded Enclosures feature similar tonal performance as P2 & P1 models, but with higher power handling capacity.
