Power supply on the amp take 12v power input and outputs higher voltage DC both + and -. The output devices (transistors usually) take the voltage from the power supply and then modulate it using the input signal to make the output the same as the input with a higher voltage.

That's the simple explanation. The complicated explanation gets into the different types of output stage topologies and different circuit designs.

but im talking about the output RCA the red and white. your talking about somthing else right. you cant transfer the voltage from one amp to the other with them can you?

signal passthru. u would use it to send signal to another amp.
