Car Amplifier Tutorial

Regardless of the specific brand or model, all car amplifiers require certain connections in order to function properly. A constant connection to the vehicle's battery is required in addition to a ground and remote turn-on connection from the vehicle's source unit. RCA cables are used to provide the input source to the amplifier while many different types of speaker wire can be used, depending on the type of speakers that will be connected to the amplifier.

• 1

  Disconnect the vehicle's negative battery terminal with a wrench, before installing the amplifier, to avoid any costly and potentially harmful damage to the electrical system.

• 2

  Inspect all of the wires to ensure that none of the wires is frayed or damaged. Frayed or damaged wires will not only negatively impact the overall performance of the sound system but can also lead to costly electrical repairs.

• 3

  Review all of the documentation that comes with the amplifier carefully to determine the correct gauge of power and ground wire for the installation. Using the wrong gauge of wire will not only negatively impact the audio system's performance but can also lead to electrical problems with the vehicle.

• 4

  Verify that the amplifier is capable of handling the impedance load of the speakers that will be connected. Using speakers of the wrong impedance can reduce output performance or permanently damage the amplifier.

• 5

  Install the amplifier in a location that allows air to circulate over the amplifier's cooling fins. Installing the amplifier in a location where it cannot adequately cool down can lead to decreased output performance and potential permanent damage to the amplifier.

• 6

  Verify that the amplifier's ground wire is installed as close as possible to the amplifier and in a location with freshly exposed chassis metal. Remove any chipped paint or other surface material that might interfere with the ground wire connection.
