i also agree.. the back tweeters will only be heard by the people sitting in the 3rd row.. other wise there sound will never make it to the front stage area,, i recommend.. good components in all 4 doors and a sub,, and you will be happy.. on that note.. for the disassembly.. grab the trim that is on the roof at the 3rd brake light and pull down.. it pops out,,, then for hte pillars start at topit pops out,.. go slow.. then disconnect the speaker. and if you hear a difference in the drivers seat well that means you need to upgrade your door speakers. lol
