I tried something new today. I had my tweeters in the sail panels at first. I liked the sound, but the stage still felt on either side of me. I wanted the stage up, and coming at me. I didn't want to put holes in my dash, so i figured out a way to mount my tweeters inside my air vents. I'm not sure if anyone else has ever tried this, but it sounds great to me. Plus it gives it a really stealth feel, with a lot of sound coming at you, but you can't see where it is coming from.
