You need to know the current to determine the wire gauge.
Amperage is always measured with the guage in series with the hot wire. That is the one wire is cut and the guage goes in line as opposed to some devices which have a hot and neutral (or ground).
A good wire gauge for car radios is 18 gauge. This wire runs between the radio and its power supply from the vehicle.
Absolutely for maximum power transfer impedance's are to be matched a low wire gauge will insure that the power is not dissipated on the wire as appose in the speakers.
Which wire is the power
The main difference between 14 gauge and 12 gauge wire is their thickness. 12 gauge wire is thicker than 14 gauge wire, meaning it can carry more electrical current without overheating. This makes 12 gauge wire suitable for higher power applications compared to 14 gauge wire.
The recommended wire gauge for connecting a Chamberlain garage door opener to the power source is typically 14 AWG (American Wire Gauge).
16 Ga wire is smaller than 14 Ga. The answer is absolutely NO!
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.
The neutral wire and power wire are never connected together.
For an electric range, a wire gauge of 8 AWG (American Wire Gauge) is typically recommended to handle the high power requirements of the appliance.
Connect the sub woofer to the equalizer or amplifier. The positive wire will need to be connected to a power source. Connect the ground wire. Connect the auxiliary wire to the amplifier.
