The P1-1X10 is a single P1 10" vented enclosure with 250 Watts RMS power handling wired to a 4-Ohm load. The enclosure is constructed with 5/8" MDF, covered in high density carpet, and features quick release compression terminals. CEA-2031 Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. 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. P1 Loaded Enclosures feature similar tonal performance as P2 & P3 models, but are easier to move in-n-out of vehicles due to their lighter weight.
