i have a crazy combo here. The alpine type x delivers High quality bass. This sub sounds VERY clean. Its an sq sub, but its still loud enough to rattle your truck. It turns heads! This sub is almost brand new, Its still VERY stiff, Its hard to move with your hand.

Here are some specs about this sub
Feed your Alpine Type-X subwoofer some serious power, and it'll unleash powerful bass to enhance your journey. And Alpine's advanced design, quality materials, and rigorous construction ensure that you'll get years of reliable use.

The SWX-1243D 12" subwoofer features a 3-layer cone — a layer of Kevlar®, a layer of plastic film, and a bottom layer of pulp reinforced with Kevlar. This design provides outstanding response and accuracy, while the cone's parabolic shape maintains rigidity and strength. The multi-roll Santoprene™ rubber surround maximizes the cone's performance with its ability to go deep. The concealed mounting gasket gives your sub installation a clean look.

On the inside, the SWX-1243D is all business. A massive, triple-stacked strontium magnet anchors the sub, while the single-piece cast aluminum frame and motor support holds provides the backbone you'll need for big bass. Increased venting and heat dissipation areas keep your sub running cool, so it'll survive conditions that would destroy lesser speakers. This bruiser can handle up to 1,000 watts RMS, so don't hesitate to give it some juice.

You can wire the dual 4-ohm voice coils to get the optimum performance from your amp, or to configure a custom setup with multiple subwoofers. Rock the bass the way you want to with the mighty Type-X subwoofer.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.
