Arrived undamaged. Fits perfectly in a grand marquis/crown Victoria trunk with 15” to spare on both sides. So still plenty of trunk left.
I was very surprised at how well constructed it was. The box had a nice smell to it like it was newly manufactured (wood glue smell). I used this sub in a 2008 Chevy Avalanche to replace a round vintage Kicker 15" Solobaric 4 ohm sub woofer. Solobarics have small sealed enclosures (1.5 c.f.). The Solobaric has nice Deep bass depending upon music playing but most of the time the bass is almost nonexistent due to lack of port and small enclosure. I believe it is rated at 750 watts RMS. I have never really been happy with any Sealed enclosures especially for my vehicles. They seem to lack the punch that I can feel that adds to the music can and efficiency that I like. My previous system had a home made ported Kicker enclosure with (2) 12" subs. That enclosure with 2 drivers was a behemoth and VERY heavy and took WAY too much space at 36" length and 5.75 cubic feet.. This enclosure was a great comprise at 4.75 cubic feet. It fits inside my Avalanche nicely with about an inch or 2 to spare from the Tonneau covers. I am using this box with the recommended SKAR SDR-18 600 watt RMS Dual 4 ohm for a total load of 2 ohms to my Alpine S-A60M 600 RMS amp. The box has a slight slope in the rear to it for looks. I think I would prefer it would be square to maximize available footprint and cubic inches but not a huge deal. Carpet is beautiful along with the logo. The wiring inside was a bit skimpy I think it was 16 gauge with snap on to connector to the speaker jack vs solder but a small issue. I could always solder a larger gauge wire and sonically it probably is not a deal breaker. I Love the spring loaded outside (push connector) types so you can remove the sub if necessary. I love the rectangular port it reminds me of speakers they used at concerts. The box is very efficient and I was surprised at the difference in volume, efficiency, and bass response when I compared the Solobaric enclosure to the Skar Ported box. this one's a keeper. I just installed a new system in my vehicle and this was definitely the icing on the cake.
Dropped a 1975 250 watt 8ohm cerwin-vega in this 18in box, pushing it with a cheap Dual 600watt amp...sounds incredible considering....Im convinced anything will sound great in these boxes...great solid build, incredible for the price.
