Great for small cars

The following review is for 12SQ, which is a part of the bundle you are viewing.

I bought this box for my soundqubed 12". It was the smallest box I could find that fit a 7" deep sub. Works great. Hits pretty hard with the sub. The inside is sealed well, which is hard to find for a prefab box.

Decent

The following review is for 12SQ, which is a part of the bundle you are viewing.

Arrived dented in the corner and it seems the cut out for the sub is slightly too large. It was for my alpine type r.

Nice Box

The following review is for 12SQ, which is a part of the bundle you are viewing.

This is a nice box. You're not going to get a ton of thump out of this box. It just isn't going to happen. I have a dayton HO 12 in it and it puts out good base with a ton of musicality. It's more of a sound quality setup. No complaints here.
