I would like to upgrade my factory speakers, what sizes are they and will i need an aftermrket head unit. Also are there any custom fit enclosures for speakers for extra cab trucks because the factory front speakers arent doing it for me.

You can find that information at both www.crutchfield.com and www.sounddomain.com If you're going to buy anything online, I would recommend either of them as they're registered dealers for the equipment they sell. 

You can run them off the factory unit, but a aftermarket unit can allow for a clearer system. 

I believe one of sponsors actually has some subwoofer enclosures, if you're looking or speaker enclosures, that will probably have to be custom work.
