no, that's incorrect in what im trying to say I follow all the steps I believe up to maybe 8? Where it says turn headunit volume up until it has a green signal light because if it's red that's to much and I have to lower it, so I did that but it tells you, that your amp has to be on full pass when you are doing this everything from that point works 100% then it says turn to lpf and press read and start calibrating, well my issue is when I flip the switch to lpf the signal light turns back off so now I can't tune it
