I was either going to do 2 more hdc3 18's for a total of 4 and about 12kw or do 16 sd 10's and about 16kw. not to sure yet, but I'm gonna do something crazy maybe 12 12's. I don't think I'm gonna do a wall though. right now I'm getting ready to take everything out and start with some deadening.... gotta decide what to use.
