That box was tuned to 32hz.
It didnt destroy the lows for what i was used to.(What i mean by that is I had a friend that had 4 12" Fosgate T1's that hit lower)
It was very loud on mid-highs.
No, no dynomat. Didnt really feel the need for dynomat with one 18". Now that I have 2 18's I severely need dynomat.
I am only running an Iraggi 220 alt and the one battery up front and never drop below 12v.
That box, if I remember right was around 8 cu ft.
If your anywhere close to kansas or oklahoma I would just give you that box. I'm running 2 18's now and that box is just sitting behind me taking up space. It wouldn't be worth it to ship. Too big and heavy.
