I am a newb. I am going to upgrade the sterio setup in my car. I have a 2000 pontiac grand am se 4 door, w/ factory cd. The reciever has an equalizer on it, no idea the specs on it though. I have 3/4 in tweeters, supposedly 4x6's in the front and 6x9's in the rear. Any idea on what to do? Also, whats the deal w/ component speakers.., are they add on to what i already have, ie. going from 6 speakers total to 10?
