I was wondering what the best thing would be for my truck. I am going to build a box under the seat in my truck and glass it in over the hump. Would it be best to do it upfiring or downfiring? I have heard different things but am not sure what to do. Also, i know it would be easier to make it fit only under the seat if i did upfiring, because i wouldnt have to worry about the hump in the floor. Thanks for the help guys.
