    That same BASH amp is 119 at Parts Express.

    What is the internal volume of the enclosure? How will you seal up the tweeter hole? Will you add any bracing? Other than those questions, the sub looks pretty good. The Theile/Small parameters look great for a sub costing under $70. One thing missing is xmax. You are doubleing the RMS power and rarely do you need to even get close to RMS before reaching maximum excursion in a home environment. Be very careful with the level settings and make sure the box is air tight.

    How thick are the enclosure baffles? If less than 3/4" I would consider removing the front baffle completely and replacing it with a 3/4 to 1 inch thick piece of MDF. Also, smear a good bead of liquid nails(or something similar) along all of the internal edges where all baffles meet. If you are keeping the front baffle be sure that the driver fits and the driver frame flange will work with the current recess.
