Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
A 12 gauge wire can support a load of approximately 2200 watts.

A good wire gauge for car radios is 18 gauge. This wire runs between the radio and its power supply from the vehicle.

To answer this question a voltage has to be stated.
A 12 gauge wire can support a load of approximately 2200 watts.
10 gauge wire will only run up to 30 amps
This is a voltage drop question and a voltage needs to be stated.

To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.
