I tried them before, And acutally I didnt think they were that bad. In my opinion, I think their good for the money. Sound quality is alright but SPL on the sub is pretty good. Gets pretty loud at times And seems louder than a Orion C-Series sub I had. I've had it for about 9 months so they do last. Isn't in my car anymore but put it in a friends and he has no complaints about it.
