These subs rock really hard, you have be sure to have a custom box that can handle them and give enough breathing. Also don't use too strong of an amp or you will blow these.

I put these subs in an Infinity Reference 1220de box (the original subs stopped working). They're wired @ 2 ohms to a kenwood KAC-9104D amp. This setup SLAMS in the back of my jeep! I would recommend maybe a custom box to go with them instead though, I think my box is a wee bit too small. Anyone who buys these won't regret it!

Let me say I started with one of these at 1st becus I'm a jl audio man to heart, but jl's are becoming so exspensive now a days. I was truly amazed at the sound of one of these 12's. So I ordered another and hooked it up and I just had to have another. Yes 3 12's in a sealed box and have not been let down yet. By me in a jl audio man to heart these subs are powered by no other than jl/ series amp. If I told you the watts you wouldn't believe me so need for the negvtive feed back. Bottom line you will be very impressed by this product. The only thing is that I think the (rms) watts are not accurate but still holds enough.

Hardest hitting sub I've had yet. This replaced a JL w3 and definitely blows it out of the water. Wouldn't recommend anything but Rockford to anyone! Only thing is it tends to overheat my amp really quick.
