CRW12D4 2-Pack

This bundle pairs two Crunch CRW12D4 12-inch subwoofers, each built around a dual 4-ohm voice coil design that gives you room to wire for a range of amplifier setups without hunting down a different sub. Each woofer handles 400 watts RMS and 800 watts peak, backed by a heavy-gauge, powder-coated stamped steel basket that resists flex and keeps the motor assembly aligned under heavy bass output. A vented aluminum voice coil former holds the 2-inch coil while channeling heat away from the assembly, and the poly cotton spider works with the pressure-treated foam surround to keep cone movement linear even as you push volume. The heavy-duty steel frame vents from the back, pulling in cool air to manage heat and extend the subwoofer’s working life. Spade-style terminals make wiring straightforward during install. With a 12.25-inch outside diameter and 86dB sensitivity, this pair suits small sealed boxes (1.1 to 1.6 cubic feet each) and larger vented enclosures (1.6 to 2.0 cubic feet each), so the build can match a hatchback trunk or a full-size truck cab. Running two together gives a system builder matched output and impedance for stereo or bridged mono amplifier setups, without mixing subwoofer specs across the build.
