View Full Version : Help with sub/port firing direction.

So im going to be getting a 15 FI Q and am building a new box for it. Its going in my 2001 grand cherokee. My question is what direction should I face the sub/port. My last setup was a 15 SX and I had the sub facing the roof with the port facing the back. It sounded really good but I was wondering if facing the sub back and port back would be better. My SX box is in my profile pic.

Sub and port back should give you a little better low-end output.

Port to the side will work well also. Sub up or to rear is about the same for me.
