LOCs not playing nice with DD1


Recommended Posts

I've been trying to tune a lot of cars that have LOCs recently but the DD1 shows distortion with little to no volume at head unit or I can't get a signal no matter what volume the head unit is put to. example today I finished up a '12 Armada 2 amps (1 4ch 1 mono). I did everything like normal, head unit showed distortion a little more than half volume than put one click down, i barely touched the gain and it showed distortion, second amp did the same thing. connected everything and the entire system had very little output. had to resort to setting gains by ear. i've seen the SMD LOC video with the DD1, I see that it's been done. what gives, I'm suppose to be saving time setting gains but just end up wasting time even using the DD1 when a LOC is present. the gain difference between the DD1 and my ear was drastic, DD1 barely moved the gain and had very little output ear had the gain just under half with great output and no audible distortion. anyone with input to why LOCs and DD1 don't get along?

if nothing changes, nothing changes
