I just upgraded my stereo in my 03 Limited.
I started as you are, just wanting to replace the speakers.
#1. They are amped in the door.
#2. The head unit will sound better with upgraded after market speakers, but the head unit should be upgraded.....Personally...Crutchfield....They supply everything.
#3. The fact that you have 6 speakers...2 tweeters in dash, means you have upgraded Infinity stuff. (I believe all them are infinity, but the 6 speakers is the upgrade.
#4. A head unit can be rather cheap from Crutchfield...120....including hardware...however, factory speakers are a bit weak IMHO.
I went Polk Components up front (to replace the tweeters...Polk rear. Pioneer HU, Rockford Fosgate Amp (barely under passanger seat...
However, it rocks...and with component speakers....WOW !!!!!
You get what you pay for. There is a few threads about changing stuff...Just speakers OR just HU...with or without AMP...
Generally speaking, the Factory units (head unit is decent, but to get the push for the seperates up front, you should either amp it or get a High powered head unit.
I never really found a stock stereo that is "GREAT'...
