My friend and I are yanking the stock system out of his new 2002 civic coupe. His stock door speakers are components with the tweeters by the mirrors. Where in the wiring scheme is the crossover located? If we yank his bottom 6.5" speaker and hook some pioneer 3 ways in there, will the factory tweeter be disabled, or will the tweeters in the 3 ways be disabled? Is there a way to get the pioneers to work completely and keep the factory tweeter working as well?
