can i use bnc cable for audio?

I have some BNC-6 left over from an A/V install and was wondering if i could use some of that for my car to run 5-channels (front, rear, and mono sub) from the head unit to the amps in the trunk.

I have the bnc connecters and can find some bnc to rca adapters... everything is 75ohm
re: golfer

1 bnc-6 wire will be alot easier (and cleaner) than 5 rca cables if you ask me...

how about using that last wire as just a signal wire (tells the amps to turn on with the car)? how could i do that? using it as a single +12v wire?
Grumpy Mac:

- You can only use 75 ohm coax for video.

contradicts:

Audio signals dont care about impedance. The 75 ohm video coax works great as long as all the wires use the same stuff.

It would work but your going to have trouble hiding those bulky wires in the floor.
