Hey what's up guys and gals, I'm Mark from St Louis Missouri and I'm currently driving my red 09 Cobalt with 4-12$ on 2k AP amp, Pioneer head unit (touch screen), 2 600wtt 6x9$ , 2-200wtt tweets (AutoZone) on stk alt. Looking forward to upgrading to my AP 15$ along with big3 upgrade. Never put it in comp but after the upgrade...who knows.
