Heat-sink aluminum cone The enclosure houses a Punch P3 12" sub, with a rigid anodized aluminum cone that holds its shape through heavy play, while staying light and responsive. The aluminum cone acts as a giant heat sink, and works alongside advanced cooling vents to direct heat away from the copper-clad aluminum voice coils. These innovative cooling techniques, plus a heavy-duty motor assembly, let this sub handle up to 600 watts RMS without flinching. The sub's dual voice coils are wired for a 1-ohm total impedance, so make sure your amp can power this enclosure safely. Advanced port design Rugged 5/8" medium-density fiberboard construction means this enclosure will hold strong for fat, heavy bass. Industrial-grade black carpet provides a clean, finished look, and protects your trunk from nicks and scratches. The spring terminals will accept bare wire, pin connectors, or banana plugs. This enclosure uses an advanced port design that promotes generous air movement, while reducing distortion-causing port noise, so you hear louder, deeper bass. Add an amp and some wiring, and feel the thick low end this enclosure adds to your ride.
