The yellow wire is the ACC. connection. This wire turns the unit on/off with the key when it’s mounted in a vehicle. You could install a toggle switch in that wire between the battery and the unit so the amp shuts down while you’re not using it. The red wire is the one that supplies the power to everything.. (Amp, CD drive, Ect..)

Yes, you can use 8 ohm speakers on it. I’m sure the head unit is stable down to 2 ohms because it’s designed to operate 4-4 ohm speakers. (2 in the front and 2 in the rear)

Just remember.. The more speakers you add to it, the more energy it will use..
