Over the weekend I finished up installing my amplifiers and door speakers. First, can I just say getting speaker wire into the rear doors is a pain in the ass!! Next week I plan to pick up an MS8, and so need to upgrade my center speaker. First of all, how do I disconnect the light sensor? I can get the center speaker grill off, but could not get the sensor disconnected to move it out of the way. I am sure its simple enough, but the clip feels so fragile I did not want to break it.

Second, if I want to run new speaker wire to the center location, is it easy enough to drop it down from the top of the dash and pick it up somewhere behind the head unit? From there it should be easy enough to run it to the trunk.

Thanks.
