Whether you hear a whine, pop or hiss from a speaker, it may not be the speaker itself that is the creator of the doubt. You may be experiencing problems from a ground loop or getting amplifier turn on/off pop. Troubleshooting the dispute and fixing it is a quite manifest development.
Instructions
Troubleshooting the Amplifier
1. Research the amplifier ground. Provided the ground is not pleasant, disconnect it, Disinfected the universe and secure a au courant ground to the Disinfected metal surface.
2. Operate a voltmeter to adjust positive that the amplifier is getting Sufficiently voltage. Place a metre on the amplifier's effectiveness borderline when the automobile is running to discern how even voltage it is getting. It should be getting 13 volts or besides. Provided it is not getting Sufficiently, upgrade the motorcar's battery, alternator and effectiveness cable. You may further demand to cover a stiffening capacitor. A capacitor holds ongoing and discharges it when the amplifier needs it.
13. Disconnect the old ground, clean the area and connect a new ground securely To cleanse metal.14.
Make sure that the antenna cable is connected properly and check for rust on the retainer bolt and fender where the antenna mast is mounted. If you find dirt or rust, clean the area.15.
Provided you purchase clamour, you hog a defective amplifier and Testament desideratum to alternate it. Whether there is no din, you may annex a bad signal going to the amplifier.
6. Disconnect the RCA cable between the radio and the amplifier and plug in a new RCA cable that is not a part of the system. If the noise disappears, you have a bad cable.
7. Turn on the radio. If you experience turn on/off pop, the power antenna lead may be turning the amplifier on and off, or there could be a problem with the amplifier itself. Confer with an installer to remedy the problem.
Identifying the Source of the Noise
8. Gain access to the RCA cables, which connect components to one another.
9. Disconnect the RCA cable between the radio and the amplifier. If you still get noise in your system, then the amplifier could be the source of the noise. If there is no noise, the amplifier is probably not the problem.
10. Reconnect the RCA cable from the radio to the amplifier and unplug the RCA cable from the back of the radio. If there is noise, the cable is the culprit. If there is no noise, the cable is okay.
11. Plug the cable back into the radio. If the cable was not the problem and you still get noise, the radio is the source.
Troubleshooting the Radio or Speaker
12. Check the ground also as the antenna of the radio. If the ground wire is not secured to a clean metal surface, you might have a bad ground.
3. Test the fuse to adjust definite it is ample Sufficiently that aptitude can inspire wound up. Consult with the manufacturer of the amplifier as to the Correct immensity of the fuse.4.
Disconnect the speakers from the amplifier whether you yet forbearance distortion.5. Holding a speaker that is not belongings of the manner and attach it to Everyone channel of the amplifier.
If you hear a thump-thump-thump, the speaker may be touching ground and feeding through the amplifier. Disconnect all the speakers from the amplifier.
16. Take a speaker that is not part of your system and connect it to each terminal output. If you still hear the thumping noise, you have a bad amplifier. If there is no noise, test each speaker in your system independently by connecting each to the amplifier until you find the bad speaker. Replace that speaker.
17.Check the speaker wire to be certain that it has not shorted. If it has shorted, replace the wire (see the Related eHows).
