Check for blown fuses and if necessary, replace them. Add the audio cables to the amplifier first and make sure the cables are securely connected. Then test the amplifier to make sure there are no issues. Add the speaker wires one at a time to make sure the connections are accurate and secure.
Why is my amp on but subs not working?
Commonly, a blown subwoofer, issues with the connection and wiring, volume and other settings, input problems, short circuits and issues with the speaker can be some potential reasons behind a subwoofer not working even if the amp has power.
Why does my amp turn on but no bass?
Step 1: Make sure that the amplifier is properly plugged in, and the power indicator is on. Step 2: Check if all the inputs to the amplifier are correct and tightly plugged in. Moreover, inspect the RAC cables if they are connected properly. Step 3: Every amplifier has certain voltage requirements.
How can you tell if an amp is blown?
How do you diagnose an amplifier? Test the sound by unplugging the sound cables or colored RCA wires. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn’t stop, then you probably have a faulty amp to replace.

What causes amp to stop working?
Wiring problems, from blown fuses to damaged wires, are the most common issues. If you’re using a tube amp with a guitar, replace any bad tubes you find. With some sharp troubleshooting, you can often fix an amp without ever taking it in for service.
Why did my amp just stop working?
If the ground connection is poor or isn’t connected at all, the amp might fail to turn on or not work very well. If the amp has good power and ground, the remote wire has voltage when the head unit is turned on, and no fuses are blown, then you’re probably dealing with a busted amplifier.
How do you check if a amp is working?
How To Test An Amplifier
- Attach the wires for power (red) and ground (black).
- Touching the amplifier’s electricity wire to the car’s battery positive post and the ground to the negative battery post is one of the easiest things.
- Link the amplifier with a mic.
- Check all accessible fuses and use one fuse in the amplifier.
What causes an amp to burn out?
the amplifier is malfunctioning
If a component dissipates too much heat, or experiences excessive voltage, it may start to burn up.
What happens when a fuse blows in an amp?
The immediate symptom is the same as for an overload—the metal ribbon inside the fuse burns through and all lights and fixtures along the circuit go dead. But in the case of a short circuit, merely replacing the fuse will likely cause the new one to blow immediately—unless the short circuit has been fixed.
Will an amp shut off if it gets too hot?
Once it gets too hot, it shuts down for protection. The most obvious thing to check is your Gain and Punch Bass control settings. The gain adjustment (or control) is a level-matching control that adjusts the amplifier to work with the electronic piece(s) used before the amplifier.
Is it OK to leave an amplifier on all the time?
But a purely electronic piece like a power amp or preamp are better left powered on at all times – with but few exceptions. So, keep the lights on with your equipment – it helps everything live longer and sound better.
How do you fix an overheated amp?
First, try adding some ventilation near your amplifier. If there is a problem with the position of the amp, place it somewhere else. If it’s in a spot where it can be ventilated but you still have an overheating problem, you can mount a cooling fan to facilitate air flow.
How long should you let an amp warm up?
As a rule of thumb, your tube amp needs to be warmed up for 20 to 30 minutes at least before you can start playing your guitar. Most of the time, tube amps have warm up specifications included in their instructions for use.
Should I unplug my amp when not in use?
Amplifiers are usually made to last for quite a long time, so the chances of anything happening to them are close to none. Naturally, the best way to do everything is to unplug it after you’re done playing. But with a good quality surge protector, there is almost nothing that can happen if you leave everything on.
Can I leave my amp on overnight?
Tubes deteriorate with use, so leaving a tube amp on shortens tube life. Many tubes produce a significant amount of heat. This heat can be drying and damaging to other parts of the amp. Tube amps can be hazardous when left on and unattended.
Are amps OK in the cold?
It has now been discovered that guitar amps can be kept in reasonably cold temperatures without problems. While some electrical components can be damaged during extreme cold temperatures, the biggest issue associated with storing guitar amps in the cold is fluctuation in temperature.
Do amps need to warm up?
A certain amount of heat in a tube amp is a good thing. Tubes do need to warm up to function properly, but the warm up time is minimal, a minute or two is satisfactory, after that you’re just wasting electricity if you’re not playing through the circuitry and making music.
