  • Quality sound on a peasant budget
Quality item.....good bass with only .85 cf3 sealed enclosure.....great if you're tight on space. Item came quickly and in great shape no issues with seller. I'm in the break-in period and only pushing half of the 600w RMS rating and the bass is not only deep but the clarity is definitely noticeable and appreciated. Can't go wrong with this item. ... show more

  • Great price for the quality Great price for the quality
These speakers cram! I have them dropped to 2 ohm running 0 gauge wire kit, a yellow top optimum battery, and 2, 2 farat caps, and 2 4000 watt boss armor amps and I tell you I can make nearly anyone shut their systems off or burn them up trying to hit as hard! I set off alarms! Cramming!!!

  • Big boom for a great price
Nice clean looking subwoofer. Plenty of power handling ability. Will fit any box with at least 5.125" of depth in box.

  • Not covered by manufacturers warranty from this seller.
My wife was very excited to have this subwoofer in her car. We custom built the box and wired it to a crossfire sub amp running 800 watts at 1 ohm. We turned the gain down from the beginning so as not to push it too hard and it blew anyway. Loud squeaking sounds from the driver and no movement at all. After researching the warranty I discovered this particular seller is not alpine authorized to sell these subwoofers, so no warranty. This sub is rated for 800rms at one ohm in the description but clearly it is not able to handle this. I've been building and installing systems for 20 years and this sub let me down. I've built sony systems, kenwood systems, and pioneer systems that are still bumping after almost a decade. This sub lasted about 3 weeks. ... show more
