maximum length of wire?

I have some video equipment i need to power off directly from my
car's
battery. I need a wire that is not too big, because i need to solder
on a special quick-release connector that will be used to easily
disconnect the cable from my video equipment. The cable requires 2
wires inside, one for positive and one for negative on the battery.
The biggest cable i found with 2 conductors, has 2x 22AWG wires
inside. Some tell me that it is too small and some say it will work
no
problem. I don't want the wires to start melting and cause a fire!
The
video gear will draw no more than 1 amp total, directly off the car's
12V battery. My question is, what is the maximum length of cable i
can
use to remain safe? Thnks for your advice.

1A through 22AWG should not be a problem, but if you're worried you
can use speaker cable....

if you're connecting directly to the battery use a fuse near the
battery. 2A wopuld be a good size.

make the cable as long as you want so long as your video equipment can
hnadle the voltage drop (10s of metres atleast) and the wire isn't
left coiled under a blanket.
