Totally off topic here but I was reminded of the office building where I work,
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.

 

Do I understand how electricity works?


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.

 

Woah... hold on....


So, do I get 16 gauge wires for my speakers and my solenoid?


Or is 16 gauge not right for my speakers?

 

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 ?
Ohm's law - Wikipedia, the free encyclopedia
Ohm's Law - Ohm's Law, Circuits, Resistance - PhET

You must have one hell of a stereo in there.

 

16 Gauge is FINE for both your speakers and starter bypass.
It is cheap and easy to get.
It has more than enough current carrying capacity.

 

Okay! 16 gauge wire.... 15 amp fuse.


Okay!
