Why does my car stereo have 2 ground wires?
It’s not unusual to find two (or more) ground wires. One is a full time ground……the other might be a ground going into the Ford timer system. This shuts stuff off after a set period to keep the battery from going dead. Some of the different ground wires are part of dimmer circuits.
Can two speakers use the same ground?
Can speakers share the same common ground? If the speakers are connected to an amplifier or receiver with a single-ended output, they can share a common ground. However, if the speakers are connected to an amplifier or receiver with a bridged (or differential) output, they cannot share a common ground.
