Hello all. 2018 Spark LS owner. Does anyone know how to remove the radio faceplate on this model year? I've tried prying it off with trim tools with no luck. Maybe I'm not pulling hard enough but I don't want to break it. Also, does anyone know the color codes for the speaker wiring? I'm trying to upgrade some stuff and add a powered sub. Not sure if the 2017 models are the same. Local dealer was no help. Thanks in advance for any and all help.
