how does amp turn on if it dosnot have the blue wire

The Pioneer GM-H100 amplifier requires both the red (ACC) and blue (REM) wires to function correctly. The red wire needs +12V from the accessory circuit to supply enough current (about 1 amp) to latch the internal relay. The blue wire provides the remote turn-on signal from the head unit. Without powering the red wire, the blue wire alone cannot turn on the amplifier because it does not supply enough current. Therefore, the amplifier cannot turn on using only the blue wire.
