heres a better pic - infinity basslink-t - in the back of my w208 230k
its really shallow so only comes off the back of the rear seats by about 7-8 inches . I was quite suprized by the amount of bass it produces though . Its a 10" powered sub with 2 10" bass reflectors either side of it. I had to trim it slightly to get it to fit but it was quite easy to do as it had a plastic lip either side for fixing . I cut then off without disturbing the inner chamber and with a little cohersion in went in nicely.
