This box is from my previous vehicle a ford ranger. But it fits in the crossfire and will suffice until I get something prettier fabricated.

The new box for the Xfire will be sealed and incorporate the Passiive Radiator that I recently purchased which can be viewed in the last 3 photos. The Boston is and will still be powered by my Alpine PDX 1.1000 at 4 ohm 1000 watts RMS
