Hello. I am looking at replacing the front 4 speakers in my 2002 Chevy Silverado 2500HD ext. cab, because the front speakers are pretty well shot. The door panel speaker set-up is bone stock (one speaker and one tweeter above it). However I am not very familiar with the electrical workings of my vehicle. Thus, I cannot decide whether to just replace the the tweeter and speaker or just buy a 4-way speaker and forget the tweeter. Only problem is, I am not sure if the stock wiring will be compatible with the new 4-way speaker. Any help is much appreciated!
