yes that is the box and please please please do not get the TYPE R SUBS
they are amazing subs when used in a ported box and SUCK BALLZ when used in a sealed box.
look at
alpine type e or type s
rockford p3 or rockford power series
jl audio w6 or w7
many other quality brands like focal, cerwin vega, re audio, fi audio,
look up
www.caraudio.com and go to the subwoofer section

you need a monster sub something that will take around 500-1000 watts since you will only have one sub and need something powerful as 2 subs to make up for the space.
Be careful i wish i knew this but the box they have is only made for 12" around 1.0-1.1cu ft which is not a bad box but for bigger subs like w7 it likes around 1.4 net cu ft. you can add polyfill like i did and rule is around 1lbs of polyfill for each cu ft.
let me know if you got other questions and i might be selling my sub box and sub pretty soon if you interested want to try something different. I have used the sub for about a month so not even broken in and box is modded for deep subs like w7.
regardless if you get the setup from nazar/wicked tell them you want it modded for a 12w7 little extra but will end up with a bigger box so you can try different subs.
