Additional details
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.
