How to Repair Car Audio

Repairing car speakers is among the most common problems car owners face. Car owners are often unable to diagnose the problem when their car speakers go silent and find it difficult to find tips on how to repair them. If all else fails, then the car audio system must be taken to a repair center.

Do the following before making any conclusions about the car audio problem:

1. Check the speakers to see if they are disconnected.
2. Check all of the fuses that are related to the speakers.
3. Tighten all of the butt connectors connected to the car’s speakers.
4. Replace some or all of the butt connectors if they look old, rusty, or broken.

If the car speakers still do not work, directly test those specific speakers by:

1. Disconnecting each speaker that does not work from the car wires
2. Connecting a 9-volt battery’s leads to each of the speakers to briefly test them out. If the speaker makes some movement or there is a popping or thumping sound, then the speaker is working and the next step should be taken. However, if the speaker makes no movement and there is no popping or thumping sound, then it is dead and should be replaced.
3. Checking the direction the speaker moves in. Did it move in or out of the frame? This helps to determine the car speaker’s polarity later on when connecting to an amplifier. If the speaker’s cone moves out it means that the lead going to the battery’s positive side is the speaker’s positive lead as well. If the speaker’s cone goes in, then the lead connected to the battery’s negative side is the speaker’s positive.
4. Testing the speaker wires by running new speaker wires.
5. Rewiring the speakers with a new wire.
6. Using the test above to make sure the polarity is correct. If the speakers move and make a sound, then they work fine with the new wires. However, if this is not the case, move on to the next step.

If the problem with the car’s speakers persist, then there may be a problem with the car’s head unit or the connections from the deck. If this is the case, it is best to either go to a vehicle stereo repair shop or get the car’s head unit manual and car manual to compare the wiring and to check if they are properly connected to each other.
