hope it has a big enuff trunk lid opening to get that 4plus cubic foot box in there.if so it surely will wang hard.my suggestion is to port a lil lower than the dd site says.they say 16sq in of port area per cuft,which is fine but go deeper than the 16 inches recommended to tune to 40hz.I went with that,i got 4 cubes net,64 inches of port opening 16 inches long.and it dose slam hard @40hz and anything between 35 and 45 hz.mine drops off at 35 and loses alot of volume so im gettin ready to build a nother box,prolly downfiring,5 cubes tuned to low 30s.on a kicker zx750.1.

You can put that sub in as little as 3 cu.ft. and it will do fine.
