Ugh ffs smd.

So i'm finally tired of gey alternator noise. Its the amp, Not tied into the headunit. If i unhook rcas, i still get alternator noise. Wtf could it be. I'm about to unhook it from the distro and try to just run the 4g into my 4 chan amp and see if its just a cheap block. I'm pretty sure of my ground too as it is grounded to the floor of the trunk. But then again. Before i pulled the system out when i thought i was selling my car, i never had alt noise. And my headunit always says failure when i turn it on.. I have no clue whats up with it. I unhooked all the harness wires as if i was running the speakers off the headunit. But since they are ran by my 4channel I only have the power, ground, and ignition wire hooked up. So i thought, he maybe im getting the failure message because the speakers are unhooked. So i hook them up, reset the headunit and still, FAILURE. Naturally. So I unhooked everything but power/ground/ignition wire and reset it again. And still, apperently I'm a failure. I wonder what could be up with it. The unit still preforms perfect and it hasn't changed other than it sais failure everytime i start it up.

As for the alt noise i'm stumped. Tommorow i may unhook the ground and rescrape the paint, idk if i got it all the first time. But idk if that could be the problem. It used to be grounded to a bolt in the top of the trunk but i lost the nut that fit and can't find one to replace it, so i can't try that again.

Somebody help meh troubleshoot. Thanks

Have you tried connecting your deck directly to the battery? Pull your deck out and see if that throws up the failure. If it does, your deck is probably a failure.

how would i go about connecting it directly to the battery.

connect the HU's red and yellow wire together on the pos side of batt and the black wire to the neg side of batt. that should keep it on. I would say its most likely the HU. that could also be the alt noise but im not sure on that.

The alt noise happens regardless of rcas connected or not
