Hey. I am doing a 5.5 ported box in a hatch of my 1995 camaro, off of a hifonics 20006D, What Sub(s) would you recommend? I want the sub to hit the lows and be pretty loud. I was thinking a 18" BL. Tuned to 36-37. Or maybe 2 15" SSDs? Not sure if these subs will be suffocating in the box that is 5.5 without displacements.
