I need help removing the packing shelf so i can adjust the rear PSS9s. I adjusted the front fine, but I cannot figure out how to remove the back part. I do have the bose sound system (2003 Turbo PCM II) and I tried to pop-out the speaker outlets but they don't seem to move.

Thanks

 

Remove the Bose the plastic port covers by pulling on them. You should see a torx screw in the hole. Remove the torx screws with the proper screw driver (a hex key will work in a pinch) and then the Bose enclosure should lift out. Be careful to remove the power connector that will be visible on the right hand side as you lift out the enclosure. Now you should see some rectangular cut outs on either side of the car. Remove the foam insulation and the PSS9 adjustments should be accessible.

Hope this helps!
