Great sub

Great sub, good tight bass. This is for folks that go for quality, not quantity. But they can hammer when you want them to.

Bass!

Got This box to put an Alpine R-W12D4 in. The box is solid built 3/4 inch MDF, all seams are glued. Carpet is thick enough to last for a while. Binding post are compression or banana plug capable. I used 12 GA. wire on the compression post, looks like it could take a little larger wire. On the inside I removed the nuts that hold the binding posts and put ring terminals on theme instead of using the spade stuff. The only thing that I wish was different would be, that the speaker cutout is a little large for this sub. I can remove material to fit a speaker, but can't add material back to the hole.
