I bought these with the intention of going IB but it is going to be WAY too much fabrication in my Sentra. I would like to get back to either 2-12" or 15"/18" in a sealed box. I will sell for the right price but would rather trade as of right now. Seeing as I am fairly new here I do have references on DIYMA (same username) and eBay (h418982). They have all been out of the box for a mock up but have not seen power since tested on 3-19-10 by Jacob @ Sundown. I will get picks up later today hopefully.
