    • Great box for the money
Review Image by Aden
This sub box is built amazing and has a great sound. The size it takes up in my trunk isn’t too bad and fits quite well. Installing this box was pretty straight forward, but due to the slanted back it’s harder to put a subwoofer in it.

    • Best bang for the buck
Review Image by edin
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.

    • Great Box, improved sound greatly.
Review Image by Jose
Overall a great box, improved the sound of my 12in CT sounds ozone greatly. The box is sturdy and sufficiently heavy enough to not move around even with sharp turns granted it is on a rubber mat. Wish the wires inside were longer but they did suffice. Great value for money and easy to fit.

    • 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

    • 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

    • 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

Had previously bought a Skar box similar to this one but my speaker didn’t fit. Returned and got this ct sounds box and my Rockford Fosgate P3 fit like a glove
