Ok so I was finally able to convince my parents to let me take apart my truck and put some new door speakers in. You should watch the Video with the back doors first even though it was filmed second because it will help you understand the front doors better. I also highly recommend watching both parts as not everything is covered in either one. Watching both will give you (hopefully) a full Idea of how to upgrade your speakers. Sorry about the darkness in the front door video. The sun set on me real fast. Hope You Learn Something!!!
