Just a quick update on the subs and box. I think these things needed more of a break in period than I am used to. They seem to keep getting louder and better sounding after each time I play it. I decided to clamp my amp and I am getting 870. To be honest I have to get a scope to see if I am clipping . I also realized that I need to do the big 3 bad because when I first start the test tone the voltage drops to 11.4 and rises back up to 12. So I am thinking with a little more break in and power I might be happy with these after all.
