Ported box, 1.75 cubic feet. Infinity's paperwork calls for a single port, 9 inch long, diameter of 3 inches, to have it tuned at 28 Hz. So I decided to run two ports, 8 inch long, 2 inch diameter (in reality they'll be more like 8 1/2 long, since I'm having them flared on both ends)
In the well/trunk area of a '91 Camaro, thirdgen Camaro, right underneath that big glass hatch.
That's where the catch may be, it's very hard to know how it'll sound, since it's not a real enclosed trunk., but I'm putting the box down as low as possible
