If you find that one pair of speaker wires or one speaker causes the amp to go into protect, disconnect all speakers from the other end of the wires and separate the wires so they can’t touch. If the amp still goes into protect, you have a bad speaker wire or the wire is shorted to chassis ground.
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.
Thereof, Do I need to ground my amplifier?
Amplifiers are a source of a lot of power, so it is crucial they are grounded to prevent any problems. … The ground for the amplifier should be directed to a bare metal area of the car body, within eighteen inches of the amp’s location. Your objective is to try to ground to the main chassis or the sub frame.
Also to know is, Why does my amp go into protection mode when I turn it up? Problem: Amplifier goes into protect. Solution: This can be caused by too low of an impedance from the way the speakers are wired, and sometimes a poor charging system (if the amp goes into protect when the volume is turned up). … That’s the most common cause for an amplifier to go into protection.
Subsequently, question is, Will an amp work without a ground? Without a ground the unit shouldn’t even power on, as the current has to make a loop from the positive terminal to the sub then back through the ground cable and back to the battery via the car chassis. Ground is just a trick to avoid running unnecessary cables and will not damage anything if its not connected.
Also, Do you really need an amplifier?
You don’t need an amplifier. An amplifier’s job is to increase the power output of your source to the level you want, and if whatever you’re using to listen to music can do that on its own: a lack of power isn’t one of your issues.

Why does my amplifier keeps cutting out?
A blown voice coil can short circuit or have much lower impedance. Another possible cause could be improper speaker connection and/or a set of speakers that do not match the amp impedance limit. … Another possible scenario would be “amp starvation”. Improper power supply and grounding can do the trick.
Does an amp really make a difference?
A better amp will make your speakers play louder and sound better, but it won’t make bad speakers sound like good speakers. Many speakers have a “maximum wattage rating” on the back. … High-end amplifier companies make amps with more than 1,000 watts, and you could plug in a $50 speaker into it with no problem.
Is it OK to not have a ground wire?
In the absence of the ground wire, shock hazard conditions will often not cause the breaker to trip unless the circuit has a ground fault interrupter in it.
Why does my amp have power but no sound?
This is a sign that the amp is being overtaxed by a subwoofer or other speakers to the point where it simply can’t provide enough power. … If you find that the amp has plenty of power for the application, then there could be a problem with your speaker wires, the speakers themselves, or the amplifier’s ground.
Will an amp turn on with a bad ground?
a bad ground (or no ground) would prevent an amplifier from turning on. not connecting a 12v+ remote turn on wire, would too, prevent an amplifier from turning on. a blown fuse from a spark will prevent an amplifier from turning on. just a personal note: take off the ground (from the battery) first before installation.
What does an amp do?
An amplifier is the device that turns the low voltage signals from your source equipment into a signal with enough gain to be used to power a pair of speakers. The functions of an amp can be split into two main sections.
What will a bad ground do to an amp?
Bad grounds can make your amp cut out, and create excessive heat, which can lead to vehicular fires. … Without a good ground, your system cannot create this current, which creates clipping issues with the amplifier. Properly grounded systems help stabilize voltage levels.
What should the gain on my amp be set at?
Turn the stereo up to 2/3 the max volume. This is the best range to use when setting gain because you avoid overworking the stereo head. If you overwork the stereo head you could end up sending distorted sounds to your amplifier.
How important is an amplifier?
How important is a hi-fi amplifier for your sound? Every stereo system requires an amplifier – it’s what breathes life into the loudspeakers. Even the smallest loudspeakers have an amplification module somewhere in their structure, only it’s usually integrated so well that it can’t be seen.
What does the gain do on an amplifier?
Your gain setting determines how hard you’re driving the preamp section of your amp. Setting the gain control sets the level of distortion in your tone, regardless of how loud the final volume is set.
Does an amp need a ground?
Amplifiers are a source of a lot of power, so it is crucial they are grounded to prevent any problems. … The ground for the amplifier should be directed to a bare metal area of the car body, within eighteen inches of the amp’s location. Your objective is to try to ground to the main chassis or the sub frame.
What happens if you don’t ground a circuit?
Without grounding, power surges or equipment damage could render electrical circuits dangerous or destructive. They could damage attached electrical appliances, shock nearby people, or even start fires. Grounding is an important safety feature for any structure’s electrical system.
