Hey everyone, new to the forum and just bought a DD-1. I have been using the DD-1 to check for distortion on the factory head unit and the lc7i and the amp, but it doesn’t light up the distortion light until it’s at max volume on the head unit, max gain on the lc7i and half way up on the gain on the Rockford Fosgate punch amp. After hooking the speaker leads up and playing music, it distorts at half volume. When setting it up I used the 40hz -5 DB track. I followed the instructions on the DD-1 manual. Has anyone had this happen? What am I doing wrong?
