Heh, I can attest to that. I accidentally made a very nice little black scorch mark through my carpet when someone sat in the back seat of my jeep, crushing through the shielding on the 12V lead. I had fused the cable, but was lazy and did it on the wrong side (near the amps)... Chris jumped in the back seat, and all of a sudden... WTF is that SMELL!!! ;8^) I'll never make that mistake again.
