I would caution you about putting an 8" sub in the center console. I did it with alot of fab work and it sounded like crap! I ended up building a custom box for behind the rear seat for one 10' Memphis sub and a Kicker 300 watt mono amp. It sounds awesome now.
i agree with above posts. i would look into makin a custom box for behind your back seat, i think you will be more satisfied in the end. if you decide to build a custom box instead, a little thinking, and you can fit a larger sub.
