  • Smaller than Skar Audio carpeted prefab box. Fits in my 300.
The box does bot fit a Skar zvx 15 sub with the rubber surround on. You will have to remove it and the sub sits in flush. Also the wiring gauge is to small. Just replace the wire. Its on the smaller side of 15” boxes. Its shorter than the skar audio carpeted prefab box. I bought that box and returned it because it would not fit through the opening of my trunk on a 2013 chrysler 300. However, this box does fit. You will have to remove the trunk latch and plastic trim and the box slides in with a little effort. UPDATE: After tuning, the box handles the low frequencies nicely the 20-28hz. anything above that and the box sounds like its about to explode lol. way more distortion than you want. Its definitely way to small for the skar audio zvx 15 sub. I will be getting a custom tuned enclosure. this prefab is for lower wattage 15" subs. ... show more

  • Great
I love the design & it sounds amazing! It was a very close fit getting it into the trunk, but it went. I run a 15" SKAR Audio Sub and I love how it sounds! I like the recessed mount so the speaker sits flush

  • Hard hitting low bass, depending on your setup
Not a big fan of the trapezoid box but diggin on how hard it hits compared to my bigger homemade subwoofer enclosure.

  • Well Made
Well made, no damage on the enclosure during shipment to my house. The enclosure is about 42.5 pound. Width is 25.5 inch. Length is 19 inch. Height is 17 inch. Harmony audio is on the top of the enclosure. Full cutout is 15 inch. Mounting is about 14.8 inch. Mounting depth is 16 inch. Port tuning at about 24hz. The speaker wire inside the enclosure are 18 AWG. You can replace it for a larger OFC speaker wire if your sub is a DVC which is what my sub is. I’ve replaced mine for a 12 AWG. ... show more
