bl 15 box

[branham1127 10+ year member]

ok, so i love bass but i havent been around car audio that long so i still dont know anything about figuring out box size and tuning.. i just bought two 15" bls with flatwind coil, p chamfer & cooling on here along with a pair of saz 1500Ds to power them. my question is, what size of box and what tuning would be ideal for a daily box with this setup?(pound as hard as possible but sound good doing it). 90% of the music i listen 2 is country but i listen 2 some rap as well.. any help would be appreciated. thanks.

What vehicle? And FI's site has box recommendations or search on here as there's countless box builds for BL's...

the truck is an 03 silverado ext cab but ive modified where the back seat used 2 be so its just a flat spot, i know as far as placement from experimenting that subs up port to the drivers side sounds best in my truck..

but i go to fi's site and it shows me everything for the ssd, q, and btl but when i click on bl its juts blank like its under construction.(their site is the first place i tried lookign) ive searched around on here and ssa forums and the results are too varied.. anywhere from 2.5-4.5 cu ft each and anywhere from 27hz to 38 hz so i was hoping some1 could give me a better answer
