Depends on who installs the radio. Usually there is a
dedicated spade for a radio, the fuse box layout
should indicate which one.

If it's on the pre-fuse side, it means that there
needs to be an in-line fuse before the radio, which is
common for older cars.

If there isn't one or it's being used for something
else, then there are adapters available that provide
two male spades for one connection to the fuse box.

Radios can be wired to be either (power) switched on
with the ignition or always powered. Your choice on
this one. I prefer always-on, so I can listen to the
radio without the ignition on. Have to remember to
turn radio off though.

Newer radios may need two power feeds, one always one,
and one switched (optional to go always power on). The
always-on one provides power for the clock,
maintaining settings, etc. The other one is for the
main operation, which again can be wired always-on or
switched.

So, there are a few choices to make, how the radio is
wired, along with what the fuse box provides to figure
out how to install a radio.
