 To connect a car amplifier in your home stereo, you will need:

  1. Locate the power supply unit that you are using.  Set up your power supply unit. Plug it in to a 120v electrical socket. Make sure the power supply unit is working by turning on the switch and making sure that the light indicator shows up on the unit.
  2. Connect your speakers to the amplifier. Measure and cut the wire to reach from the positive and negative power supply to the positive and ground on the amplifier. Match and connect the negative power supply to the ground on the amp, and the positive power supply to the positive amp. Connect a separate positive wire from the remote section of the amplifier to the power supply.
  3. Get the sound working on the amp. Locate your RCA (audio) wires. Connect the red and white plugs to the audio outputs on your home stereo receiver. Next connect the other end of the cored to the RCA inputs on the amplifier. 
  4. Make sure everything is set up and working properly. Plug in the power supply for the amp, and flick the switch to make sure that the power button is turned on. The indicator on the amplifier should be green to indicate that power is getting to the amplifier. Turn on your home stereo and turn the volume up to make sure that are getting sound. Make any adjustments any levels on your amp that you need to.
