loving them
I've had the subs for a while now and they're great, great performance and they hit really hard, especially for the price. My only concern right now is whether or not the amp I have pushing them is strong enough but they are still great

Great for the price!!!
Just bought these subs not to long ago, just got them yesterday and got them installed to they hit hard for what they are. my boy has kicker cvrs and i competed with him and blew him away. he was seriously mad to find out how much less i payed and how much more power i beat him with. Get the right amp and amp kit for it and your set

not so impressed
After owning the subs for 2 weeks, 1 of the subs had blown. The lights that go around the subs stopped working. The plastic crackles when the temp is cold. Just yesterday the other sub had finally had it. I would suggest upgrading to the Kappas.
