It’s not bad stuff if you just want some bass and don’t really care about brands / models, but I’d pass on it and put that $300 towards better stuff, or just save that 300. It isn’t stuff like "OMG I can’t pass that up", I would not buy it normally at that price. On the other hand, for simplicity's sake, if you’re not an audio nut it’s already installed and functional and I'm sure sounds fine, so you won't have to do any installing yourself or pay someone to do it, assuming you even want subs in your car.
