  • The perfect prefab box for a Kicker CompR 12
I bought this as a last resort before giving up on a Kicker CompR 12 I had in a different box. This box has almost the perfect specs based on the Ts parameters of the CompR so I took a chance. This box brought the CompR to life and it’s hitting lows it couldn’t achieve before in a smaller box at the same tuning. The box is well made so I expect it to outlast the sub installed in it. ... show more

  • Worth it all
Box is made extremely well it is some very thick mdf compared to a Skar prefab box and it sounds amazing and plays down to nearly 20s and hasn’t even fallen apart from a 2000w 12

  • Best bang for the buck Best bang for the buck
IMO one of the best prefab boxes on the market. Sturdy, built with 3/4” plywood, and it looks great!! I have a Sundown sub in it and it shakes the windows on the house from the driveway. Sounds great, spine realigning deep bass.

  • Nice quality and hits really low
I believe it's a little small for the Prodigy Audio NB512 that I have in it but I was extremely squeezed for space and it still sounds very good and hits very deep

  • Ct sounds 12 inch kerf port sub enclosure.
Great build quality and great sound. I was told by a reputable car audio shop in my town that the 12 inch sundown sub I installed in this box would destroy the box and that the sundown sub I have has to have a custom built box. So far this sub enclosure has been great and have had zero problems with it. Highly recommend, can’t go wrong for the price. ... show more

  • Speaker cutout too big
Box screws won’t align with subwoofer the cutout if too large for most subwoofers I’d be surprised if their own brand could fit in the the build quality is great but what sense does it make if you can’t secure your speakers properly to it… you might be lucky to get at least 2-1 screws not secured if you mess around with your speaker. ... show more
