I am adding pioneer three way 6x8's in my door this week, but i also want to add tweeters at a later time, what i was thinking about was adding the tweeters in the door like most people have, and then put the supplemental woofer to each tweeter in the rear panel behind the seats. will this make the acoustics messed up?i know the wiring will be goofy with the long wires but i can handle it, i am just wondering if it'll work. any help will be great

 

With the long wires and crossovers, you will lose your fade bias. In my opnion this will make it sound funny. My advice is just stay with the three way 6x8s you are putting in, they have a tweeter already in them.
