I have recently gotten a Pioneer DEH-7500MP head for my car. Now i am looking to upgrade the speakers and get some subwoofers. My car takes 6 1/2" speakers all the way around so i was thinkin get a set of component speakers up front and then some regular 6 1/2's in the middle and then either 1 or 2 subs not sure yet. and then gettin a 4 channel amp for the speakers and either a mono of a 2 channel amp for the subs. So if anyone could make any suggestions it would be greatly appreciated.
