How to Hook Up a Car Amp Inside the House to a Wall Outlet

by Nichole Liandi

If you've got a car amplifier you'd like to use in your home, there's one major obstacle to overcome: how to power the amplifier. Wall outlets provide 110-volt AC power, but amplifiers require 12-volt DC power. You'll have to do a little extra wiring, but the problem is not insurmountable.

Step 1

Look up the input power specifications for your amplifier, using the manual or the manufacturer's website. Find the specification for current draw in amperes.

Step 2

Purchase an AC to DC power inverter. Make sure the inverter can produce a 12-volt DC output at the specified amperage rating.

Step 3

Cut a length of 10-gauge red wire, a length of 10-gauge black wire and a length of 16-gauge wire, each long enough to reach from the amplifier to the inverter. Remove 1/2 inch of insulation from each end of the wires with your wire strippers.

Step 4

Loosen the power terminals of the amplifier, marked "+" and "-", with a screwdriver. Loosen the REM terminal of the amplifier with a screwdriver.

Step 5

Slide the ends of your wires into the loosened terminals and tighten down to clamp the wires. Insert the red wire into the "+" terminal, the black wire into the "-" terminal and the 16-gauge wire into the REM terminal.

Step 6

Loosen the terminals of the inverter. The method and tool will vary by brand. Slide the black wire into the "-" terminal and tighten. Twist together the ends of the red wire and the 16-gauge wire, slide them into the "+" terminal and tighten.

Plug the inverter into a wall socket and turn on the inverter to power the amplifier.

Items you will need

  • AC to DC power inverter
  • 10-gauge insulated wire, red and black
  • 16-gauge insulated wire
  • Wire cutters/strippers
