Heat doesn't really penetrate the car's headliner (otherwise, it'd be very hot inside your car the moment you expose it to the sun). Hindi siya parang yero na sobrang init.

Also, the cable still has its housing, it's not exposed. The housing won't melt unless you subject it to really really hot temps like a soldering gun. From the inside out, it also won't heat up unless the + and - wires are grounded, but since I didn't touch any of that, it's safe.

Worst case scenario is an oversupply of voltage from the AC power, but that's why I had a fuse installed for additional safety.
