This is mainly aimed towards Dakota owners, but has anyone tried the Kenwood KSC-SW1 powered subwoofer? I have a quad cab 2nd gen dakota that I cannot afford to lose any of my main space, thus needing to put a sub either under a seat or behind the backseat (except the mtx custom one, it's a ripoff). I just want to know how you think it sounds and how easy it is to setup...
