It is absolutely possible. He wants it under the bar to access the spare. That does not limit you. You have lots of space behind there as well. It just won't slide in and out like the prefabbed boxes out there. It needs to be a cutom build to be correct IMO.

 

that 12" w7 needs at least 2 feet net after sub and port

i feel it would be very difficult to do if he does not want the baffle to extend any farther toward rear of car than the strut tower

between the sub $
the custom box that i still feel is a hard build and would be on the small side
and the amp needs to be a Jl 1000.1

$ 550 sub
$ 900 amp
$ 350 custom box

all that money and not enough get up and go

just think ends won't justify the means

 

I have seen a 15'' sub in a 350z

 

me too
mine
