Running Wires Through Door
I’m in the process of upgrading the awful stock sound system in my ‘16 C300. There are no tweeters in the door, and I purchased a pair to run active (no physical crossover). Doing so requires me to run an additional pair of speaker wires through the door. Upon popping the wiring boot out of the door, I discovered that this may be easier said than done. Does anyone with more expertise/experience with this model have an idea of how to go about this?
