Hello, I have a 02 Jeep Grand Cherokee laredo 4.7 v8. Its just plain without 4x4 or leather seats with a single cd player. I was wondering if I got a aftermarket 100 watt 4 speaker sony or pioneer mp3 cd player for about $100-130 with the 4 speakers. Will it sound any better?

If not how could I get better sound, nothing outrageous, but something loud and clear. I could buy anything online, but I don't want to have to go into a audio place and have them install it.

thanks anything will be appreciated.
