Posted April 16, 201114 yr im makiing a temp system for now in my 95 grand prix. i am needing help on how much port area is ideal for these subs. going to be pushed by a alpine mrp1000 at 2 ohms. the sub is a brand new alpine type r 12. thank you for your time.
April 16, 201114 yr Try a side firing 4" aero port in a 2ft^3 enclosure tuned to 33hz will yield a port length of 13.625". Face the Sub back.
April 16, 201114 yr The general rule of thumb is 12-16 square inches of port area per cubic foot of box. Hope this helps and good luck! Edited April 16, 201114 yr by Dutchie.
