DIY Car Amp Repair

There are a variety of reasons why a car audio amplifier might malfunction, most of which render the amplifier useless until it has been fixed. Most car amplifiers are fitted with a function that completely shuts the amp down if there isnt a complete circuit connected to the amplifier, but it may not help you fully diagnose the problem. Most problems lie within the wires themselves, so making sure theyre repaired and working properly is key.

Instructions

    1

    Find the red wire on the left side of the amplifier. Connect one end of the voltmeter to this wire and the other end to a piece of exposed metal. This should make a complete circuit. If the amplifier does not power on following this, then the problem may be with the amplifiers wiring.

    2

    Find the ground wire at the back of the amplifier. The wire is black and should be attached to a piece of exposed metal. Apply a piece of electrical tape to the ground wire and attach it firmly to a piece of exposed metal if not already connected. This creates a full circuit.

    3

    Remove the white fuse from the fuse terminal located on the left of most amplifiers and replace it with a new one. A blown fuse will generate no power for the amplifier, rendering it useless.

    Stick pieces of electrical tape to each wire that is coming out and into the back of the amplifier. Each wire is partially exposed at one section to allow a connection to the fuse terminal. However, this can cause short circuits, and the connection between these wires and the fuse terminal isnt vital as it is powered by the main wire running on the side of the amplifier.
