I paid $800.00 for this setup last march, and has been unbelievable. Definitely changed the way I felt about driving a single sub. There is still MTX warranty left on this unit as it was bought from Powered4Sound which is a "brick and mortar" authorized reseller along with the Snailshell obviously, and if you've ever heard a snailshell setup before, you know why they are expensive. This was hooked up to a 1501d and runs flawlessly great. If you want something that gets loud and sounds clear, send me a pm. I'm asking $600.00 for box and sub.
