Hey y'all... I have a 2018 Pete 567 with the concert class stereo. My sub stopped working. I found the fuse blown on the amp so I replaced it but still not working. Does anyone know if there is another in line fuse on the main power wire going to the amp? The amp is located inside the sun box. It has 6 wires going to it. So I'm guessing that the fat red wire is the main sub power but it disappears in the paneling. I don't have a multimeter with me to check for power so just looking for another fuse if there is one. Thanx!
