Hey whats up im looking for help with a box design. I currently have a slot ported box I built that is 4.2 cubic feet and tuned to 32 hz. I'm looking to go to areo ports i have 2 6 inch pipes i have a sundown type x series 15 in d2 with a spl cone and night shade soft parts and coil its on roughly 1500 watts rms to about 1833 watts rms goimg in a 2007 chevy trail blazer im trying to get a low. Around 30 or 31 hz would be my preferred turning 32 sounds good the box I built sounds good just a hobby for me to build another with areo ports any help on a design would be really awesome i see alot of smart people on here and would really like to learn
