That post serves no purpose. The output is totally install dependent and vehicle dependent. So the numbers mean nothing to the OP. Well, OP said he wants a sub that gets low and loud. I was simply demonstrating that the 13Av.2 is an SQ sub that plays extremely low and clean notes but at the same time can get extremely loud. That and it doesn't break the bank. I was simply stating what was done in a smaller box with less power than the OP had, so he can obviously do even better than that, depending on the car he has. The car wasn't a SPL setup, just a daily driver.
