ive got an 08' cclb , i wanted more bass also , so found a q-forms box that fits in between front seat and back seat right in the middle on the floor(like a center console), it was made for the extended cab 05-07,but still fits mine ,w/ 2 cup holders its tan and has a punch 10" sub it sounds great , ive been looking into a custom box for my cc for even more bass, so looking to get rid of my set up
