While wiring the amp power cable, i left it for day unconnected to the battery, but unfortunately the next day, i ran my car quite a lot and the engine got really hot. It nearly melted the wire! check the pics..
The picture below is the melted plastic. I was worried that it would stick there forever, but once the engine cooled down a bit, i was easily able to remove it.
Power wire connected to the battery. the fuse holder is screwed to the battery case.
Power wire coming out from grommet
Grounding point for my amp
My amp and sub.. its all a mess!
My custom made amp on/off switch. its connected to the amp remote turn on and the 12V acc cable to the stock stereo unit.
Possible future location of the amp switch.
