Well, seems like you're packing some decent audio. I assume you have amps and a head unit capable of powering it all properly?
My guess is probably need to recheck the wiring, and how much power you have going to any particular set, it just sounds like your system is imbalanced. I mean, that's my guess. Also, this is probably the wrong section, there's an entertainment section or something where you could get much better advice.
