How to Hook Up a Car Stereo in Your Home

By Nichole Liandi

The modern aftermarket car stereo is a pretty amazing device. In a compact package, it contains a CD player, AM/FM tuner, high-powered amplifier, and a variety of other features, often including auxiliary inputs, USB connections, and often even Bluetooth. With their compact size and rugged build, a car stereo is an excellent way to add a stereo system to spots in your house like garages, patios, and work rooms.

Things You'll Need

  • aftermarket car stereo
  • wire strippers/cutters
  • speakers (pair)
  • speaker wire
  • crimp connectors
  • 12-volt DC power supply

Step 1

Connect your stereo to a pair of speakers. Car stereos usually have outputs for two pairs of speakers, so you can add two pairs if you wish. If you're going to add only one pair of speakers, use the outputs for the "front" speakers. The wiring harness of the stereo will have color-coded wires for each speaker. Connect these to the correct speaker with your wire cutters, crimp connectors, and speaker wire.

Step 2

Connect your stereo to a 12-volt DC power supply. Consult the stereo's manual to determine the amount of amperage your power supply will need for operation. Connect the red and yellow wires of the stereo's wiring harness to the (+) positive terminal of the power supply with crimp connectors, and connect the black wire of the harness to the (-) or "ground" connection of the power supply.

Step 3

Mount the stereo. Fabricate a simple metal bracket to hold the stereo in place, by cutting a piece of steel 2 inches wide by 11 inches in length. Bend the last 2 inches of each end of the metal at a right angle. Hold this up against the top of the receiver, and not where the mounting holes on the side of the receiver are.

Step 4

Drill a hole on either side to match a mounting hole. Mounting it on the underside of a shelf is a good way to keep it secure and in easy access at all times. Attach the bracket onto the underside of the shelf with wood screws, then attach the receiver to it with bolts (the correct size varies from receiver to receiver;10 mm often works). Make sure the stereo is level so that it offers the most dependable performance for CD playback.
