Alright guys, after spending an hour or so learning about flared ports, this is what I've come up with to do.
8CUFT. Tuned to 35Hz - Two 15 HDC3A-'s, 4kw.
6" x 17" Precision Ports, cut down to 6 x 12.16 inches total length.
Car stereo's calculator says to avoid port noise:
Minimum Usable Vent Diameter: 12.92 in
Min Area: 131.15 in.
So with the flared aeros I've planned, I should have:
12 In Diameter,
Area: 343 Cu In per aero, so 686 CUin. Total Area.
This sound like a solid plan so I can pull the trigger on buying the 70 dollars worth of aero ports?
Thanks guys. First time doing an install of flared ports.
