the janitorial staff has a vacuum cleaner with about 100' of speaker wire as the
power cord.
Yeah, that's UL listed, I'm sure....

50 Amp Speakers?
Ohm, maybe???
I don't mean to sound condescending, but do you understand how electricity works?
Two years of EE doesn't make me Tesla, but perhaps I assume more than I should of the vast majority.

I can respectfully say no.
(Why do you think I keep asking all these questions)
Why, what gauge wire should I use for 50 amp speakers?
If there is a chance I can use the same gauge speaker wire for my speakers and my ignition, that would be great... But, I don't know what gauge wire to get.

50 amp speakers, that's a wrong mixture of terms, it's like saying you've got 50-gallon light
bulbs in your house.
I think whatever gauge speaker wire you end up buying will work fine for your solenoid....
EDIT: I think he's talking about speakers that can handle 50 watts.

So, it's amps, not watts... 
If your speakers were a purely resistive load you could use Ohm's law to simply determine wire size.
50 Watts @ 12Volts = just over 4 Amps
The chart I posted before would tell you you only need 23Ga wire for your speakers.
Speaker Impedance Explained - Ohms
AudiogoN Forums: Speaker wire guage/current draw ?

You must have one hell of a stereo in there.
