noob question

hi im new to the site i joined so i can read and learn everything on here, but i had a quick question, i have in my daily driver (90 eclipse gsx) a 10" mtx terminator (TN10-04) sub in a truck slim box and a bridged renegade amp pushing it (REN550s) i was just wondering how i can get a little bass for my setup or what i should switch out or any ideas i went with this setup because i got it from the brother everything was brand new and i gave him 40 bucks and my gsx has almost no room in the hatch because of the spare tire hump and its a tiny trunk! anyways i would really appreciate some help or tips, thank you very much
