1994 Camaro and a 3512

well..thought i'd share the progress on this system, it's in a 1994 camaro with a digital design 3512 12" sub. it's a dual 2 ohm setup running off a kenwood 1600 watt amp (kac-811D??) the subs sitting in a net 3 cu/ft with 45 sq/in of port space. i wont have the spl number untill this weekend but were hoping for mid 140's , final looks of the system will be carpets and smoothed into the rest of the trunk, throw in some LED's and a much better amp.
