So much debate but i like it lol. With your install having so many variables and having such a great affect on the final sound I come to a conclusion that most of if not all these mentioned subs are great. Just comes down to personal preference, past experience, and budget really. I liked my 15" Fi SSD and really wanted to stick with Fi when I decided to get something different but I jumped on the sundown nut hugger ride with all there hype around here. Think i'm gonna try 2 loaded 12" Fi Q's for my next subs. How much power will a loaded Q handle?
