I have an 02' Chevy Trailblazer and I'm putting in a system thats gonna be ~1000 watts rms, so it's going to be decenetly loud. The stock speakers definitely will not be loud enough, and I'm not trying to break the bank, so I'm going to replace only one pair. Which pair would be best to replace? The dash speakers (3 1/2), or front door (6 3/4). I'm not sure what brand I'm going to go with, but I always get quality equipment. Which pair will be best for the highs?
Also, is it worth going to a shop and paying big bucks to get a system installed the 100% correct way, or would it be a value to go to someone I know who has done installs and get it done for like $50?
