Hey guys, I was originally thinking I was going to go with 2 FI Q 10" or Icons, but moneys tight as many of you would agree. So ive decided 1 FI BL 15" would be better, going to be running off a SAE 1200.

1 thing im wondering is if I would have enough enclosure for the sub. I ran some numbers and I can get 15h X 32w X 12d without sacrificing much of my trunk which i think turns out to be around 3.4 ft.

What im wondering is if that would be enough space, or if I should get a little more like 3.5 after displacement and port.

Could someone also explain to me about the significance of port area. Im guessing the larger port the louder? Or the more air moves?

You don't want the port to choke the amount of air that the woofer uses. You also don't want too much port as the woofer needs some back pressure.

I believe the general rule of thumb is 12-15sq inches of port per cubic foot.
