Car Stereo Repair
Have you ever experienced problems with getting your car speakers to work? Since I think many of us car owners have experienced this problem, I will provide this description of how to diagnose the problem of silent speakers and also give you some hints on how to fix it. Whether you are familiar with car stereo repair or not, this might help you. If it doesn't, contact a dealer who can do an auto stereo repair or search for vehicle stereo repair help online. If your stereo speakers don't work, then try
- checking the speakers to see if they are disconnected
- checking all fuses that are related to the auto speakers
- tightening the butt connectors to the speakers
- replacing all or some of the butt connectors
If your speakers are still not working, I recommend that you test the auto speakers that don't work directly:
- Disconnect each speaker that does not work from the car's wires and do the test below, doing one at a time.
- Use a 9v battery and connect its leads to each auto speaker to be tested for a short moment.
- Does the speaker have movement?
- Do you hear the sound usually known as a 'pop' or thump?
If your answers to the questions above are 'yes', your speaker will probably be able to make sound and it is likely to work.
- Also note which way the speaker are moving, whether in or out of its frame during the test. Thus you can also determine your auto speakers polarity when connecting them up to the amplifier up in the front.
- If the cone of your speaker moves out of the basket, the lead going to the positive of the battery is the positive lead of the speaker. If it goes in the opposite direction, the lead hooked to the negative of the battery is positive of your auto speaker.
This speaker direct test has two possible results: Either the speaker is not able to make sound or it is. If the first is the case, your speaker are dead and you must replace it. If the latter is the case, you should
- run new speaker wires and rewire
- Perform the 'popper' tests to get the polarity correct as described above
Now, if this problem still persists you can at least rest assure that the reason is not your speaker. The reason is probably one of the following: Either it is caused by
- problems in the deck itself or
- the connections from the deck.
In this case I recommend that you contact a vehicle stereo repair shop or do a search online to get information about how to fix these problems.
