I answer dumb posts with dumb answers.
The OP did not put what type of car has.
The OP did not put his budget requirements.
The OP gave almost no information except for the crappy speakers he plans on using.
I understand car audio very well. I currently run a SQ system in my car with a Pioneer Avic-Z2 Head unit, all old school MB Quart drivers, and a JL Audio sub.
I guess I should have tried harder to help this Noob with his vague question, my bad, I am sorry.
