Trying to install an amp and subwoofers to my 2017 wrx premium. I having trouble on we’re to wire everything up. Do I have bypass the factory amp and what will I need to connect the amp and subwoofers. Where do I connect the rca on back of the stereo or by the factory amp.

If you have the factory amp, it will be best to connect your amp and subwoofers to the output of the factory Harman Kardon amp and run those signals through a Line Output Converter. If you're amplifying the OEM speakers, you may want to do something to bypass the factory amp. Not sure.
