Hey guys I'm sorry if this question came up already but I couldn't find an answer. I just bought a JL 12w7 and it seems nearly impossible to find a box for it which will fit it under the strut bar. i have seen one custom built box in another post and im attaching the pic below, but does anyone know where I could purchase one or if anyone here builds them what kind of prices should i be expecting? Any help is greatly appreciated! Thanx!
