new speakers?
 

I've finally got my 2 12" subs and once they're in my next aim is at my speakers. I have already installed 2 JBL P953 6x9s in the back window/trunk area but I have more to do now that I notice my stock isn't what I thought it would be.

I've got a 96 sedan deville and there looks to be a 5 1/4" speaker as well as either a mid or a tweeter (looks odd i cant tell) in each door. I've got to get 8 new speakers and I need a few ideas on 2-4 channel amp + speaker combos

I was thinking some JBL P552's in the doors and to replace the mid/tweeter with a JBL brand to keep it linear. I have no idea what kind of amp i can get that will do the trick, or if i'd need 2? any help please
