hi, what type of equalizer should i buy? i really don't know how to adjust the professional type of equlizer...i have an audio control eqx, but i do not know how to use it, so am planning to sell it and buy a less complicated one.

my system is headunit, pioneer keh-p7950, competition series mb quart, 2pcs kicker solobaric 12c and rockford 200x2 and another amp for my separates

to tell you honestly, i think the sound of my setup *****!! it lacks some voice and staging, i guess...

can you give me some advice? thanks
