im looking to make a 4th order for my 2 sundown SA 12's and put it in my trunk of my honda accord. i wanna have it so i use up most to all of the trunk. if any one has done a design for 2 of these can you post the measurements of the box internal and external. my max dimensions to work with are (33 1/2 D x 36 W x 17 H) also can you post the port length and dimensions because im going for a 50hz tuning so my low end is arounf 20hz -30hz but i can still hit those mid-lows like the 45hz to 80hz. i really need help this is my first box build ever and i wanna make sure its done correctly. im powering these beasts with a hifonics bxi 2061d amp pushing 2400 watts rms at 1 ohm.
