It doesnt sound nearly was nice as it did when it was in the cabin.
If i lean it againt the back seat facing the cabin,,,what is being more of a filter,,,the cushion material inside the back of the seat, or the thin cardboard that is on the trunk side of the seat back...If i made a hole thru the cardbord and secured the sub there, would it be any better?
what if in addition, I removed the volume of stuffing the seat has, so at least i get a 10" hole, but I keep most of the seat intact, and no one from the outside would be able to tell...
