Well basically i was doing a system on a budget, who wouldn't try this sub? but with reading some reviews i was worried about it just going bad on me. To be honest, i bet the people that it didnt work properly for underpowered it. I purposely waited 6 months to write a review to make it an honest one. Ive been pounding this sub with a 3000 watt amp, just under max, so roughly 2500 watts max to this thing. it kept pounding away. It actually still is, im just waiting on getting my amp back because my amp went before this sub did. So power it like it says, because its been taking it for 6 months for me.
