[QUOTE="jim010, post: 8855418, member: 689674"] Hello, I bought an Android double din head unit. It is a 8 core 8 GB RAM 128 GB ROM LTE from Aliexpress. Everything works in the Android head unit I bought, but I did have to figure out the wiring situation on my own. Problem I am having is that the back of the unit heats up very quickly within a minute or 2 (area circled in red) even if the unit is turned off. It heats up to the point that it is almost hot enough to burn skin (At least that is what it feels like). I know it is a heat sink, but why soo hot? And if it is an amplifier, why is it so hot so quick when there are no speakers wired up? It is not the speakers or anything else, as I only have the 16 pin ISO power plug connected - nothing else. So I have it narrowed down to that plug at least. But I still can't figure out why it is heating up like that. I unpinned everything in the power plug except for the ground, ACC and the battery+ and it still really heats up right away. My wiring seems ok. Hoping someone on here can tell me what I am doing wrong? The part that gets really hot is right above the power plug on the right. The rest of the back is nice and cool. Just that one part. Here is how I wired it: 8 pin power plug (A) to Android ISO 16 pin power plug pin 8 to pin 1 pin 7 to pin 3 pin 6 to pin 4 pin 5 to pin 8 (I disconnected this to see if it was my problem, but nope) pin 4 to pin 2 pin 3 not used pin 2 not used pin 1 to pin 5 (for reversing camera - works) Suggestions? This getting really hot thing is concerning.
