Here is a little test of my first try on building a box for my car. The first way I had it set up was the worst. it was not loud in the car at all just shook the back window a lot. second was better with the sub and port facing in. third is best where the port is firing directly through with one seat down. going to build a new box very soon. planning on making the port shoot right into the cabin and hopefully none into the trunk.
