I am still trying to put together my system for my 06 Milan. I have a Pioneer 600w 2 channel amp and a 12" Alpine sub in a ported box. I want to get 6x8"s for the front doors and another amp to power them. Any sugestions for an amp? I would like to keep the headunit stock. Will I still get a loud clear sound from the stock 6cd indash headunit if I power the new 6x8"s with an amp? Or should I start looking into headunits?
