Taken4granted

Several years ago I had my stereo upgraded along with the door speakers and rear passennger area. now I had a monsoon setup with 8 speakers and they asked me if I wanted to bypass the trunk speakers, I agreed. but now I want them back as well as hooked up to the factory amp. does anyone have a diagram of where the wires run through out the car so I can trace where the bypass is at?? anyones help is greatly appreciated
