Well if your having a shop do the work or are handy enough heres my advice.
If your upgrading the fronts do it right. Ditch the poor designed 4x6 speakers and step up to a 5.25". If you go components pop the tweeters in the sail panels.
Now if you will be running a subwoofer, DONT get 6x9's. Rather than that, pull them out and leave the holes open. This ports the trunk to the cabin.
Amplify the front speakers. This makes a WORLD of difference in itself. It will make the sound much richer, fuller and accurate.
Memphis is good. Im sure its their big seller. I wouldnt just buy the first thing, I would audition a few speakers then make a choice.
A very powerful piece of advice: You get what you pay for!
