for the components in our doors I was wondering if anyone knows how to take them out and replace them with rockford fosgate 8inch subs. Ive seen them in the CDC show cars and some others but cant figure out how to put them in.

 

You will have to make custom inserts in your inner door panel. 8 inchers dont just bolt in. You must pull your door panel off first, unscrew your stock mid and get an idea of the work involved. If you have never performed this custom work then I recommend taking the car to a stereo shop and let a professional do it
