Unlikely at audio frequencies. Everything in an amp or receiver is close to metal- the chassis, back plate, bottom cover, etc.It's not impossible .. there's an EMF field around those wires
Move one 6 inches away from the metal on one channel and see if you can hear a difference between the two channels..
If you can.. then flip flop and move the opposite channel ..
You'll have your answer ...
I used speaker wire to power my Cibie driving lights on my Opel GT back in the late 70's. The insulation melted and the wire touched the body. I blew the fuse on the lights. But they were fine for my hi-fi.
It's got to get pretty warm to melt the insulation enough to cause a short. A heater vent should not be an issue at all.
On a side note, I don't think Metal will do as much damage as punk.

I loved those things. Mine was yellow. I replaced the big round turn indicator lights in the front with "bow wow" small headlight housings and installed Cibie halogen pencil beam driving lights and did "friday nighter" rallies. I connected them, via a relay, to my high beams switch. I had standard halogens in the main lights. One of the other rally guys said that at one time when I was coming at him it looked like "A 747 coming in for a landing".my older brother and I both had 1970 Opel GT's in the mid 70's, he still had 2 when he passed this December, great little cars.
we raced side by side one night on a rather curvy rd at speeds of 105mph, my superior tires and worn clutch made it an even race until one particular turn. His rear end slid out a bit to the right and he was mine the rest of the way BWAAA HA HA HA, I miss my older bro.

BTW, I owned it for years before I finally rode in the passenger seat one day. I did not know the drive shaft was not in the center. There is definitely less room for the passenger than for the driver. I also put a rear axle on from an Opel Kadet that came standard with the rear anti-sway bar. It was standard on European GT's. I just popped out the nylon plugs over the bolt holes in the frame and bolted the anti-sway bar to the frame - instant European suspension.
It's also the reason I bought my Scion FR-S. It is, for me, a throwback to the Opel, except it handles a LOT better and kicks out a heck of a lot more HP from the same 2000 cc's. I've put 190,000 miles and nine sets of tires on that thing.

HA! I put the Radial TA's on mine! Remember when 60 series tires were considered "wide"?my brothers other Opel is yellow with black striping down the side. mine was orange but I had it painted white, and with BF Goodrich radial TA's raised white lettering it looked awesome.
His other GT
