I have two 8-inch W0's in the back of my extended cab 1998 F-150. They sound decent, but do not go very loud. I would not recommend. I have them in a box that was built by JL for F-150's also.
Yea..originally i had 4 of the 8w0's in a Bronco and they got pretty loud just not loud enough. Now i built a stereo box for my 4wheeler and I put 2 of them on that and have two left over
