Has anyone here run the front doors active, allowing the mids and tweeters to have their own separate channels? If so, how much of a pain in the ass was it running additional speaker wires from trunk to front doors?

Front fully active four-way with :
Under-seat woofer, door panel with 6.5“, 4” midrange, tweeter
It doesn't look difficult, but I had it done by a professional.
The cable went through the door connector.
