Alpine BassLine Series 10" 4-ohm subwoofer

If you're a car sound enthusiast, you understand the importance of bass. Alpine shares that view, and they've created the BassLine Series 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. Alpine's BassLine W10S4 10" sub is built around a polypropylene/mica cone that stays stiff at high volume levels 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.
