Car audio system is an integrated part of a car that is to be maintained well by the user. A road travel without a pleasant music for the ears would make it more tensed and irritating one. So one must have a regular check over his car audio system to avoid break down of that system leading to unfavorable situations. A repair in this system may become a nuisance while traveling. A professional will always charge the owner more than what the repair actually costs. If one comes to know how to repair a car audio system he can avoid this unnecessary expenditure being spent for an audio professional.
There are few tools required for accomplishment of this task. The usage of such tools will reduce the man power required and makes it easy to complete the task. It may include a set of new fuses,a screw driver, a fuse puller.
The first step after disconnecting the battery of the car is to remove the dashboard. This can be removed by taking out the screws that support the dash around the stereo. After it is unscrewed, the dash is removed and placed aside. The screws that were removed are also kept careful.
The dashboard around the audio system will have few or many screws fixed. Those screws are removed first using the appropriate screw driver. The stereo will be fixed in the car by another set of screws. These screws are also removed using the appropriate screw driver.
Next step one must use a fuse puller for removing the fuse wire from the stereo. This is important because it is very delicate and sensitive and might get damaged while performing the operation. These fuse are present in the back side of the stereo.
The harness for the wires is then replaced and plugged back in position. The antenna cable is also plugged back. The respective screws are replaced. After this, the dash is kept back in its position and screws are screwed back.
By doing the above steps, the audio system is generally fixed. In case it does not get proper, there could be a problem in the fuse of the car that connects with the audio system. Using a manual of the car, the fuse box is located. In that, the fuse that connects the radio can be located with the help of the diagram in the manual. After that it is removed by using a set of fuse pullers. The fuse is examined. If there are signs of the fuse being blown out, it is replaced with new fuse.
This article on how to repair a car audio system discusses on two major types of faults that occur with the stereo. There could be a blown out fuse either in the car or in the radio.

The amplifier is an important part of the entire music system. It makes the music audible and also gives clarity to the audio. The amplifier is generally given with the music player set bought sometimes can be bought separately. Some connections have to be made to the aftermarket amplifier. The connection must be grounded properly for the proper working of the amplifier. For this the wires that are meant for grounding are secured by attaching it to a nut or a bolt of the car. Grounding is very important and also makes the circuit complete and also gives power. The ground connection is made as negative terminal by fixing to any metal body of the car whereas the power line connection is from the positive end. This can be achieved by following the instructions on how to properly ground a car stereo amplifier.
Certain tools are required for accomplishment of this task. Tools make processing easier and less time consuming. The process of grounding a car stereo can be easily accomplished using simple tools like ground wires and of course an amplifier for grounding.
Now before seeing the instructions for grounding the amplifier we see the things required . We ll need an amplifier and a ground wire. Firstly the negative terminal of battery of the car is removed from connection . This is mainly done to ensure safety as this may avoid short circuiting
The next step is to decide the place where the amplifier is to be mounted. This is considered a very important step. There must be a gap for 18 inches from the car amplifier to the ground. Over heating is another problem which causes damage to the amplifier. So care should be taken to avoid overheating. This can be avoided if the amplifier is mounted in a well ventilated cool place inside the car. One such place is the trunk of the car which is very useful for mounting the amplifier.
A wire is then connected for grounding. The connection is to be made from the ground output of the amplifier. The ground output might not be known immediately and therefore reference can be made to the circuit diagram of the amplifier. But sometimes there are labelling made pointing the ground output connection on the amplifier.
Next we shall determine where we have to ground the amplifier. The best places for doing this is usually screws or metal nuts. So fix a screw or nut eighteen inches within the amplifier.
When we look at the ground wire we will observe that it has a metal lead . Unscrewing of screw or nut is done and place the lead of wire. Then the screw or nut is bolted . This makes the ground wire to remain fixed firm into a place. If these five steps are done perfectly grounding of car stereo amplifier becomes complete. There is a common mistake which people often commit while grounding the amplifier. They don’t remove the paint of bolt or nut. In that case proper connection between the metal body and ground wire is disrupted. Such imperfect grounding is dangerous to the appliance. So always use a paint remover to completely wipe off the paint around the bolt and screw. Further tips , warnings and suggestions can be had at ehow.com.
The problem of short circuits and other types of electrical problems causing damage to the amplifier can be avoided if one knows how to properly ground a car stereo amplifier.
