This was yet another instance in recent times, where time and technology have brought about great improvement, making a simple replacement into a significant upgrade. The stock speakers in the 2000 GMC were leftovers from the 90s if not the 80s. Cardboard cones and lousy tweeters by today's standards were probably pretty good for a truck in 2000. And now for the best part of the whole deal. I got a set of replacements at Best Buy that were far superior in range, wattage, and quality, for $40. Incredibly cheap for a vast improvement in sound.
