How long should an amplifier last?

You should replace them every 10 or 20 years, and there is a high chance that your amp will sound as good as new. Of course, if there are no issues with your amp or the sound, then you should not change a thing. Probably the best thing about amps is that you can easily tell if something is wrong.

Why is my amplifier not working?

If the remote turn-on wire doesn’t have power, your amp won’t turn on. If the remote and power wires both check out okay, the next thing to look for is continuity on the ground wire. If the ground connection is poor, or it isn’t connected at all, the amp may fail to turn on or not work very well.

How do car amplifiers work?

Electronic transistors typically amplify the audio signal in a car audio system. Using electronic components such as capacitors and resistors, an amplifier boosts an inaudible line-level signal from your head unit so it’s powerful enough to move a speaker’s cone back and forth to create sound.

What happens when an amp blows?

In most cases, an amplifier will blow fuses due to internal damage caused by the way it was installed. An amplifier that blows the main power fuse immediately after you turn it on or when the fuse is inserted into the fuse holder is usually damaged in its power supply or output section, and will require serviced.

What would cause my car speakers to stop working?

When all of the speakers in a car audio system all stop working at once, the problem is usually in the head unit, in the amp, or in the wiring. In some cases, an issue with the wiring between the head unit and a single speaker can even cause all of the speakers in an entire car audio system to cut out at once.

Why is there no sound coming from my car speakers?

Typically when a car stereo produces no sound it’s usually caused by a shorted or grounded wire, defective speakers, faulty head unit/fuses, or setup is not yet complete with your radio unit.

Why do my subwoofers cut in and out?

For some reason, the subwoofer cuts in and out anytime the volume is around 36 or higher. The head unit goes up to about 60, the bass eq is set to 0 (goes from -24 to +6). The gains are set very low, bass boost off on amp. Messing with gains provides no difference either.

Will amp turn on if fuse is blown?

If the fuse is present and blown, the amp can’t turn on because the circuit providing mains voltage is open. Simply replacing the fuse may or may not solve the problem.

Why is my amp in protect mode?

Some amps go into protect mode if they get too hot, which can prevent a permanent failure. The common cause of overheating is a lack of airflow. If the amp is located underneath the seats, or in another confined space, that may cause it to overheat.
