Question about Sony Xplod XM-1652Z Car Audio Amplifier
With all amplifiers for a car, you must have the main power connections B+ and ground connected, and then you must also have the remote turn on connected as well. This is the way the amp turns on. It comes from the radio and is usually the blue wire from the harness off the back of the radio. When the radio is turned on, the blue wire gets 12 volts sent to it so it can turn on an external device like an amplifier or the power antenna. Make sure you have this connected to the amp and that the radio is turned on. Then check the voltages at the power terminal of the amplifer. You will have the ground, the main B+ of 12 volts, and then the turn on voltage of 12 volts. If you have all of these, then you need to troubleshoot it more. It will turn on without the speakers connected, but I am not sure why you would want to connect it without the speakers. It will also turn on without the RCA cables connected for the audio input as well. But just to turn on the amplifier, all you need is those three things i mentioned. Let me know if you require any further help.
