5050LED lights with 14.4W/1 meters, power 12V-360W can take 25 meters? I mean RGB, if it's connected to the color
Reckon the power: 14.4*25 = 360W, see power and power on the surface is the same, this is actually a problem, make full power power, it's easy to burn, only half done, it is recommended to use two power.
For the second problem, 360/12 = 30A, the current large, general electric wire is unable to load the current so high, and you want to see in the light there is no equipment line, if not, it should be every meter to connection to the power supply, if any, every four to five meters should also be wiring to the power supply voltage, so as to ensure the basic stability of the position
