my buddy ordered 2 9kv.2s and a nine.2x from ED and put them in a small sealed box in his s10 behind the seat. These are 8 inch subs, and they are loud. They are dual 2s which means the max wattage he's getting to them is about 200w a piece, but we only have the gain turned half-way up. so thats really about 100w a piece right now. these little eights thump extremely hard. much, much harder than i anticipated. they will hit 3 of the 4 bass notes in Put On by Young Jeezy. they almost hit the 4th low note. i would strongly recommend these to anyone who has a single cab truck and wants to put subs in. i really couldnt believe how loud 2 of those things were.
