So the stereo install is coming along pretty well. I got the harness setup and ready to go, pulled the stock amp and spliced all the wires, replaced the 2 rear seat speakers. But, I am leaving the door speakers stock(they sound like new). How should I wire them in relation to the separate tweeters? Can I just run the tweeters in parallel, or do I need something in line to block out the lower frequencies? Also does it matter if the tweeters are in phase with the rest of the speakers? < This will be pretty much impossible to do since the wires are not color coded with any reasonable color.
