Everything is sounding real good but I need to find out where my headunit clips and then can set the gains on my amp. My headunit goes from 1 to 63 volume. I’m just assuming headunit clips about volume 47 just to be safe. I have a Liumy 2001 handheld oscilloscope and have 2 test tones 50hz -5db and 1000hz -5db. When hooked up to let’s say LF speaker leads out of headunit I’m not getting clipping on 50hz or 1000hz. It’s not a high end oscilloscope but it’s showing the voltage, freq and sine but it’s not showing a clip at any volume. I even tried the rear speaker leads just in case. I can take a video tomorrow when it’s daylight to show you the signal but as of now it’s not making sense.
Any any input would be awesome
