drozovs Posted February 3, 2007 Report Share Posted February 3, 2007 I was curious if I can ground all three wires together in my '07 STI or if they each need to different ground screws? Thanks! David Quote Link to post Share on other sites
sportsfan21 Posted February 3, 2007 Report Share Posted February 3, 2007 You can ground them together. Just make sure you have a nice neat, clean ground. If you are using the existing ground wire from the stock radio, you might want to use one, heavier guage wire and ground those three straight to the frame. Just drill a screw into an unpainted piece of metal. Quote Link to post Share on other sites
