Input:
I bought two of these. Installed in a box 40 inches wide by 10 inches deep and 16 inches tall and they hit amazing. Didn't expect to get any 'bang' for 17 bucks but these definitely do the job. Can feel the bass for a good 50 feet away when I crank it up. Would rate 5 stars if it came with something telling you the recommended volume of the box.
