So currently my setup for the rear speakers: Pioneer GM-6400F Amp Pioneer Premier TS-A943P Rear Speakers I changed the speaker wire from 18 gauge to 16 gauge, and I started having issues with the amp going into protection mode if I adjust the HU bass settings or if I increase the volume too high. Can someone explain why the lower gauge wire will cause this issue? Should I be using 18? Is there something on the speaker specs I should be looking for to decide which gauge to use? Thanks!
