  • New price for used parts. See review.
The media could not be loaded. As you can see from the images, the subwoofer screws were removed/replaced prior to me receiving it. I’m sure this thing was refurbished and packaged like it was new, and the way it sounds like the subwoofer is about to die already. The setup is also cumbersome; they provide two straps with some wall screws & brackets. You have to basically mount the brackets PERFECTLY to get this sub from rolling around and the straps felt flimsy for something constantly kicking out bass…. Speaking of bass, it’s not enough to warrant the price. I moved it around to several locations (trunk, back seat, even the front passenger seat aimed at the driver’s seat) and I just wasn’t impressed at all. I expected better from Alpine but this thing is a dud. The fact that you also have to pay to return it sealed the deal for me. Save yourself the trouble and go with another brand. ... show more

  • Feel your insides shake with this sub!
This thing hits hard. I have it hooked up to a Rockville that pushes 360 watts rms. I tuned the amp to the subwoofer and when the bass drops you feel your insides shaking and it almost takes your breath away! My windshield shakes so hard my rearview mirror won't stay in position! I do have the gain turned down on my amp slightly to match the recommended rms watts of the subwoofer. For the price and the quality of sound I would definitely recommend to friends, family and neighbors or anyone else asking "WHAT DO YOU HAVE IN THERE?!" ... show more

  • For Deep Not Fast Bass
I bought my 12" Alpine sub for VW Passat. First was 8" 150W one :-( Alpine Fits perfectly with extra room left in any dimention. Quick easy connection with banana plugs. In my case plugs not so secure in place. Had disconnection issue. Always mount and secure sub to the floor before use. Do not let it roll in the trunk for max performance. Or operating at all lol Sub very boomy on max. I would recomment installation of Bass knob too for volume adjustment. Tube subs Not situable for quick bass. Like in Techno music. Pop music sounds wonderfull. Bass Very deep and enjoyfull with right music. ... show more
