I also tried the speaker behind the seat, not a worthwhile option. Custom auto sound has some options, under seat component set, or replacement kick panels with speakers. I am leaning toward under seat, maybe move the tweeter up higher. I did not like the idea of cutting anything. Yellowbird has a nice setup, I did not think that speakers would fit there easily. http://www.custom-autosound.com/prodFam.php?CatID=3
