So i’ve owned this car only about 4000 miles the first week i didn’t really have any issues then I started my car one day audio didnt work at all had to restart my car until it worked and then I was good then i started experiencing clicking / popping sounds and it would just cut in and out which is what it does all day now it works for 30 minutes then doesn’t work for an hour or it cuts in and out for an hour not sure if it’s just the AMP or the whole thing is cooked just lmk what I should do to be able to listen to music again also for my backup camera also just turns off randomly while in reverse.

Your amplifier is failing. The crackling sound and backup camera cutting out are classic signs. You need to repair or replace the amplifier in the trunk.

Amplifier failing or needs cleaning, the amp location is near some vent which causes dirt to enter and cause problems, disconnect it and clean it with contact cleaner, also clean the wiring cables (clean thoroughly), and using a blower or hair dryer (cold air of course) clean the amp fans and let all that dirt and dust go out, reconnect and check again. If it keeps failing, then you need to replace from ebay or repair at specialized audio center.
