Hello, new to the forum. I am looking at putting an 18 in my new Scion XB. I have my eye on Fi Audio. However I am unsure of which model to buy. I am going for good loud bass but also want a sub that can hit everything smoothly. The BTL seems to be a strict SPL sub so that's out of the question. I was looking between the BL and the Q series. The Q series is their SQ sub and the BL apparently is their between SPL and daily driver. Anyone have any experience with these? Also, is it even possible to get a 5-6 cft box in the rear hatch area of an Xb?Thanks for any help guys!
