Six Methods:Is it the amp?Test power wireTest REMTest groundCheck the fuseRe check again, make sure amp is the problem



Method 1 of 6: Is it the amp?

  1. 1
    To make sure the amp is really the problem, look to the side. All amps have a green power led light and a red protect led light.
  2. 2
    If both the green or red light are not on, then continue to the next steps.

Method 2 of 6: Test power wire

  1. 1
    Make sure the power is connected securely to the battery and connected properly to the 12V terminal on the amp.

Method 3 of 6: Test REM

  1. 1
    The REM tells the amp that the radio is on and it should be too. It's a small wire that extends from the radio, its usually blue and very thin.
  2. 2
    To check REM power, place a small wire in the 12V terminal and then place the other end in the REM terminal.
  3. 3
    If amp turns on, then REM is the back of the radio is disconnected.

Method 4 of 6: Test ground

  1. 1
    Grounding the amp is extremely important and somewhat deceiving. Check the ground wire is secured to an unpainted metal part on the body or chassis of the car. It is important that this wire is not loose or flopping around.
  2. 2
    If the ground is not secured properly, the amp may be on, but produces a very dim power light and does not play bass. There is a simple way to check if the ground is properly secured or connected to a true ground that leads to the chassis of the car, it will be explained in the warning section.

Method 5 of 6: Check the fuse

  1. 1
    Pull the fuse(s) out and make sure the piece of metal is not broken inside the plastic housing.

Method 6 of 6: Re check again, make sure amp is the problem

  1. 1
    At this point, there is nothing else that can be the problem. If it is not the power, ground, REM, or fuse, then the amp is blown
Add your own method


  • As stated before, there is a way to make sure the power wire is connected to the battery and/or the ground wire is connected properly to the metal part of the car. Note that this is very dangerous and should only be done if necessary,
    • Make sure one end of the power wire is connected to the battery and the other end is not touching any metal or other wire
    • Make sure one end of the ground is secured to a metal plate and the other end is not touching any metal or wire
    • Very carefully and quickly tap the loose ends of the power and ground wire together
    • A nice spark should occur, if it does then both wires are secured properly.
    • If a spark does not occur when both ends of the wires touch, then the wired are not connected properly on either end
    • It is possible that the ground for the wire may not be good enough, move it to a place with more exposed metal in the car and try again
