So I'm new to the forum and pretty new to owning a spark. Currently I am getting ready to install some new speakers, JBL gto429 and planet audio trq462, I may look into putting 6 inch in the front and 6x9 in the rear at a latter date. But for now I am also going to install the Rockville RW10CA 10" 800 watt powered sub and I need help finding a wire diagram for the stock mylink head unit. I would like to be able to wire the sub to the head unit instead of tapping into the rear speakers. Any help or advice would be appreciated.
