^^^ Yeah I hate them LOL. They suck at midbass, they suck at bass in general (perhaps not all the fault of the speaker, since the enclosures are too small). Plus, you upgrade yourself into a corner with these. Once you decide you can't stand them, and you want proper mid- and sub-bass, you need to take them out, put back in the OEM woofers (or something else), and then install the trunk sub. Furthermore, you may buy an amp for the Earthquakes, that is not powerful enough for a trunk sub.
