So is the backlighting inoperative on the stereo normal? This has to do with the stereo right? Not the wiring?

I plan on changing it out soon so i just want to make sure my new unit will light up.

Which size of speaker do you guys usually go with in the front? 5 1/4"? Can i pick up a set of components that replace just the front speakers and tweeters without an external amp or crossover? I am sure it should sound ok.

I am pretty sure i have just the regular stereo system in my 1999 GP GT.

Is it worth swapping out the 6x9s? Also how hard is it to replace all the speakers in the grand prix?
