I have power control wires coming from my car harness, head unit, and amp. Do I connect all 3 together or just the wire from the amp to the one from the head unit?

If there is an OEM amplifier in your vehicle, and you are also installing a woofer amp, then yes all 3 wires need to be connected together. The blue/white wire of your radio is the Power Amp Turn on lead. It needs to be connected to the turn on lead of every amp in the vehicle.
