Hi sifus, I need some help with my car audio, i recently went to change my headunit into an android headunit. For the first day, the audio everything works fine even at higher volumes but then after the second day when i tried to increase the volume it started to have cracking sound. I am using stock speakers for your info. What seems to be the problem? Any solutions its's really annoying that I rather not listen anything at all.   https://www.youtube.com/watch?v=-6NXp-_RSUQ
