Gunz That Turn on Nunz
The wave is not towards the rear its to the side and the trunk is pretty big, the box is as far back closed to the rear trunk lid as possible. Not that close to the seatswow, im surprised to hear this.
I was under the impression that if your sub was facing forward, (its going to be close to the back seat) and your port is toward the rear of your vehicle, you get cancellation issues as the back wave is out of sync with the front since they are emitting from locations like 3 or 4 ft apart from each other.
