i have this sub in a sealed box with 600 watts to it and it hits hard! it gets all the low bass but not the high bass, i want to buy two more. i don't recomend this sub in a car that doesn't have dynamat, i have a truck and it echos hard.

These subs slump, I run 900 watts to 2 of them and they knock...plus they arent too expensive, they are sick...plain and simple
