Car Audio Repair
Car audio refers to the sound of either a car radio or CD player. The audio is transmitted through the vehicles speakers, although some vehicle owners may have upgraded their audio system to an amplifier system, which produces considerably more in sound. Car audio can suffer from problems such as no audio or high-pitched audio. When this happens, it needs to be repaired, either at home or at a car audio shop.
General
Car radio repair involves repairing the whine or hum of radio audio as the engine speed is increasing and decreasing. This problem is caused by an alternator that has been improperly shielded. In addition, when the wipers or brakes are activated, they can cause a voltage spike that travels into the audio system. This will affect both radio and CD audio.
Amps
The installation of car amplifiers can enhance the sound, but they are not easy to do yourself. And if youve noticed a change in your audio since youve installed amplifiers yourself, they may have been installed incorrectly. The many wiring steps for the amplifier may trip up the amateur. Plenty of guides are available online, but the best bet is to leave this to the professionals.
Mechanical
Your car audio may also be affected by other issues, such as a damaged antenna, which means you will have trouble receiving a radio signal. If you have a tape cassette or CD, inspect them before inserting them into the tape or CD deck, as they could have dust or dirt on them. In addition, sometimes the stereo system will need repair because of mechanical faults caused by dirt and moisture.

How to Troubleshoot Bose Car Audio
The Bose corporation manufactures high-end audio equipment, including car audio systems. Bose car audio systems include dynamic frequency speakers, high-performance head units, and thickly insulated sound cables. Occasionally the Bose car audio sound systems may need troubleshooting due to wear and tear, damage or user error. Some of the methods used to fix a Bose system include master resetting, cleaning the head unit, and speaker replacement. By personally troubleshooting the Bose system, a car owner can avoid costly trips to car audio repair shops.
Instructions
- 1
Reset the Bose car audio system to fix most display or playback errors. Remove the faceplate of the Bose car audio head unit by pressing the release button in the bottom corner of the unit. Locate the small port in the top right corner of the unit (left corner for Bose units in European vehicles) marked "Reset."
2Flatten out the paperclip and poke the end into the small reset port (this is also possible with a pin). Hold the paperclip in for 15 seconds. Replace the faceplate onto the head unit and turn on.
3Remove the face plate again if playback issues still persist. Point the long nozzle of the compressed air canister into the Bose CD player/MP3/Tape Deck port. Squeeze the trigger on the air canister in short two-second bursts. Spray around the edges of the unit as well.
4Replace a blown Bose speaker if the sound from it is distorted. Use the screwdriver (with special Bose-style hex bit) to loosen the casing of the grill. Remove the grill to access the cone of the speaker. Remove the Bose-style connectors on the cone by hand.
5Remove the blown clone. Replace with the replacement cone, and lay in the speaker casing in the same fashion as the broken cone. Re-connect the Bose-style connectors by hand. Replace the grill and tighten with the Bose hex bit and screwdriver.
