Re: SUBWOOFER box for sy??
40-1/4"W x 14-3/4"H x 6-1/2"(D1), 3-3/4"(D2)
Atleast from my experience, those dimension look like they will fit behind the seats. If will be tight, but if I had to guess it would be a 80% chance with seat all the way back. At the most you would lose one click.
I am not sure it will fit behind the center console though, I think its just over 6" You might be able to get it to fit with the rear wall padding removed. The other issue is that 40" is really wide, you might need to cut out the jack assembly. Its also just one 10" with two passive radiators, it might actaully sound decent if the 10" is in the middle so it will have some room to breath.
