Hello im new to the forum. But I have just go back into doing audio again after five years lol. But I'm starting to work on my trailblazer ext which has lots of trunk space. But as of now I'm using a Rockford 700x punch 4 channel and one SSL sta120 lows for my hifonics Olympus xxv 12" 1ohm. I'm going to build another box though. I can't position it well when its a deep box in little space behind my third row. Any tips on positions of the sub or box size could benefit alot.
