I've put a few of these boxes in one in my wife's car and the other in a Customers car and they both loved it
I put a Kicker CVX 12 in this box, paired on a 500 watt JL Audio amp. It hits harder then I would have ever expected. Great box but it’s big. So make sure you have the room. This is my second Fox Box.
Nicely finished, well constructed enclosure. Mine does not feature the unique port design shown in the product photo. It is a simple slot port instead. Still works as intended but could benefit from some bracing as I do experience some flex. I may dowel it in the future. Paired with an EMF Lowballer - I experience about 4db of boost around the tuning frequency which seems to be the advertised 30hz in my application. It slams.
Great build and sound quality for the $. I own 3 of these and have 0 complaints.
