How do I find the wiring to check for loose wires for dead left front speaker in 1994 C-280? Also, is the door panel removable if a replacement is needed. Thanks to Scott in Lajolla for help in selecting the correct CD changer -alpine chm630 with mbzalp9 adaptor.

YOU CAN actually remove the speaker panel with the door panel on. If you look under the door directly below the speaker, you'll see a screw. Once you've unscrewed this, the cover pops off. Then you have access to the speaker and wires. Good luck!
