bro, I just swapped the battery and it worked immediately.. I feel so dumb lol, thanks man!

Tried it out on 2 home audio amps, still nothing, I'm starting to think I might have a defective unit.

Salt-4 now connected to rear channel of headunit instead of sub, gains are now set to about 1/4 instead of 3/4, (using DD1) Tried using the cc1, and same exact problem as before, no signal light.

with head unit maxed, playing track 14 from cc1 disc A(63hz )I got 2v from front left channel, 2v from rear left channel, and 0.37v from left sub channel... I'm gonna re wire the amp to the rear channel instead of sub, reset gains, and then try again.

I'm going to go check how much voltage is coming from rca's at the back of HU

LPF is all the way up(250hz), and HPF is all the way down (10hz)

Hi, I just got the dd1 and cc1, dd1 worked flawlessly. I am running a sundown salt-4, with an alpine UTE-62BT which claims 4v rca. I have followed the steps word for word, and cannot get the signal LED to illuminate, I start with HU volume at 0, and you can barely see the power LED, and as I turn up the volume, the power LED get brighter and brighter, but even with HU maxed out(no distortion at max), bass knob maxed, no signal LED. I have tried reading from speaker outputs, with negative on battery ground, negative to speaker output negative. I tried using the RCA outputs of the amp. I have tried using a USB and bluetooth to play the tracks. I think maybe the headunit just doesn't put out a strong enough signal, as my gains are set to like 70-80% at -5 gain overlap. Brand new knukonceptz rca's run to the amp as well.
