Description

Skar Audio introduces the SK1X18V subwoofer enclosure to bridge the gap between competition-grade quality and universal fit pre-fabricated enclosures. The SK1X18V subwoofer enclosure is a 18-Inch, universal fit, ported, subwoofer enclosure that is designed for maximum bass and responsiveness. Finished in a premium black carpet and featuring the Skar Audio logo on the lower left side, This enclosure will look sleek and attractive in any application. Volume: 4. 75 ft^3tuning frequency: 29 cut-out Diameter: 16. Mounting depth: 13. 50"When setting out to offer a line-up of premium, universal fit, subwoofer boxes, The end goal was to deliver a final product that was unlike anything else available on the market; setting new standards for quality and performance. The enclosure features a kerf style port, which means that the port construction utilizes the curves typically found only in custom, high-end, professional enclosures, allowing the box to offer deeper and more accurate bass. Furthermore, it’s precisely tuned to ensure that it delivers riveting low-end frequency response and the type of bass that turns heads from outside the vehicle. The Differentiating features that put this box in a league of its own don't stop there though; this 18-inch vented enclosure also utilizes high- end materials during construction, ensuring durability and reliability. On top of its outstanding craftsmanship, this box is also braced for extreme strength, and can handle even the most brutally powerful woofers. Internally, we line several walls of the enclosure with poly-fill to enhance the overall versatility and depth of sound that this enclosure reproduces with any given subwoofer. The premium push terminal wiring cup, that is built into the side of the enclosure, features 16-gauge speaker wire that is pre-soldered and connected to the terminals, making it easier than ever to wire up and install your subwoofer. Enclosure Dimensions: Width: 25. 75" X Depth 1 (bottom): 23. 625" X Depth 2 (top): 19. 75" X Height: 21. 375".

  • Great box for the price
Size: Dual 12" Style: Dual
Overall it's a great box. My kicker comp r's fit into it perfectly and it sounds/ is built better than the original box they came in. The only problem for me was a little damage on the corner (most likely dropped/ damaged in shipping). It's not noticeable but it's definitely there. Would like to see better protection with shipping, but the overall best box on amazon for the price. ... show more

  • Best bang for the $
Size: Dual 10" Style: Dual
Highest quality prefab box out there at a price you can’t beat. Car audio shops in my area would build me a similar box for quadruple the price. Arrived on time with no damage. Tight box that hits low.

  • Skar box
Size: Dual 10" Style: Dual
It is a great subwoofer box but to small for my DDX-10S. This box would be perfect for IX, vd and sdr but nothing else over them classes of subs. I broke the baffle on the box due to not having enough airspace.

I could have took the time to build my own but decided to go ahead and buy one and I’m glad I did bc it wouldn’t have been as tough as this bad boy.

  • Sounds good but looks like poop
Size: Dual 12" Style: Dual
After the 1st day of use, the carpet in the port already was loose and flapping with the bass. I was expecting better quality from Skar, not having it fall apart after the first day
