Alpine's BassLine subwoofers will add some serious rumble to your vehicle's sound system. You'll really feel the impact of bass lines and drum beats, so you can get into your music like you never have before. These subs also live up to Alpine's reputation for making subs that bass lovers want, but they don't cost so much that you end up actually living in your car.
The tough steel frame helps to keep your bass punchy and accurate.
Built Alpine tough
Alpine's BassLine SWA-12S4 12” sub comes equipped with a rigid polypropylene/mica cone that won't flex under high volumes and cause distortion, while its poly-foam surround will last for years to come. The tough steel frame offers the stability you need to keep the bottom tight during intense bass sessions. This sub handles up to 250 watts RMS and its 4-ohm impedance makes it a great match for most amplifiers.

This sub is absolutely by far the best sub I've ever put into a box and installed in my car. Extremely well packaged and protected when shipped with no damage whatsoever to the box or product. It was so good I ordered a second and will be ordering a third very soon for my dad.
