Alpine W12S4

Holding down the BassLine
If you're a car sound enthusiast, you understand the importance of bass. Alpine shares that view, and they've created the BassLine Series of subwoofers to give you the low-frequency punch you need to create a well-balanced system. You won't just hear the bottom end, you'll feel it. And best of all, Alpine's made these subs affordable so you can fill your vehicle with bass without emptying your savings account.
 
Built solid
Alpine's BassLine W12S4 12" sub is built around a polypropylene/mica cone that stays stiff at high volumes to avoid distortion. The poly-foam surround and tough steel frame give the cone the support it needs to pump out the volume. This sub handles up to 250 watts RMS and its 4-ohm impedance makes it a great match for most amplifiers.
