Actually, I don't have mine installed yet but I'll be putting it in a 4c/ft box ported to 30-32hz powered off of a Sundown 1500d at .5ohms and I might strap another 1500d depending on how it handles the first 1500d. Let me know how yours turns out and post some vids if you can.thank you i cant wait...box is in process of getitng built...tuned to 28hz... hey beerdrnkr how does it sound and what box u have it in?
