Why does the C63 have such crappy bass? I be blastin my homie Game and there is NO SUBWOOFER

I need to shake the entire hood when I roll through! So I'm thinking of just getting one of those bazooka subwoofers in the trunk or something. Is it possible to just get one of those and not an entire system? I don't wanna mess up the electrics or anything. If I do put it in there, how do I control it without one of those ugly radios that you find on civics? Would the bass setting in the control center control that? Can anyone help me?!? In case there's a difference mines an '09
