How do you change door speakers in a 2002 Chevy Trailblazer?

Answer 1

The door speakers on Chevy trailblazers become intermittent over time and will quit with temperature variations until finally they will no longer work. I tried to replace the speakers with a cheap pair of aftermarkets thinking anything is better than factory, but not true. After much research and finding that aftermarket component speakers are more expensive than factory and being told I need an amp to drive them and other baloney, I decided to spend the $100 a piece and replace the whole speaker assembly. Good move - the low end is back where it should be. There were actually low notes in songs that I could not even hear on the aftermarket speakers!

To replace simply pop the trim around the interior door handle. There are metric bolts that hold the door panel on. Remove these. Pry the panel bottom away from the door. Lift up on the panel it is hooked on the top edge of the door. You may wish to disconnect the plugs for the switches. Unplug and Remove the speaker assembly from the door. Replace with new assembly and reinstall door panel in reverse order.
