How to tune an amp with a multimeter. Mostly the cars have an amp attached to the dashboard which plays an active role in providing you with a good quality of sound in a long drive.

How to tune an amp with a multimeter

Tuning your amp with the help of a multimeter does not include complexities. The article includes all the essentials concerned with the procedure. Be patient while reading.

Type of the multimeter to get an amp tuned

Mainly, there exist two types of multimeter which as follows,

  • Analogue multimeter.
  • Digital multimeter.

Both of the types vary in price and function. The analogue multimeter works on a manual mechanism whereas, the digital multimeter has developed functions as compared to the ones present in the analogue multimeter.

The analogue multimeter has a needle present inside a visible glass which further moves back and forth in case it senses or reads the presence of the flowing volts.

On the other hand, the digital multimeter has a display screen and multiple options attached to it so that you may have better experience in collecting the accurate values of the resistance.

So, make sure that you utilize the digital multimeter for tuning an amp because it has greater accuracy as compared to the analogue multimeter. That’s why you are hereby advised to bring the digital multimeter into your utilization.

Cutting off the power supply

For turning an amp, first of all, you need to cut down the supply of voltages from the engine to your every device. You need to do it carefully with your hands covered with gloves.

The wires are tiny in shape so keep the pressure light and do not attempt to handle them with a firm grip of your hands. It will damage the copper present beneath the layer.

Establishing the connection

Having disconnected an amp, you need to establish a strong connection of multimeter with your amp. Keep in your mind that the digital multimeter has two external probes in red and black colours. Both of the probes do not contain any socket for capturing the bare copper in an amp.

Rather, they have plugs attached to both ends to have the copper sensed. Make sure that you establish the connection by taking the signs on the terminals into your account.

Displayed values

The multimeter will read the values and display them on the screen after sending the copper present beneath the wires. The reading should contain Ohms units and it should be somewhere between 2 ohms and 15 ohms. That would be the calculated measurement of the resistance with the help of a digital multimeter.

Consulting the user’s manual

Make sure that you keep the user’s manual with you while operating the said procedure. Once you have the values of resistance measured by the multimeter, open the manual and start consulting the values.

If the measured values do not match the written values on the manual, consider either replacing or repairing your amp. Make sure that you do not decide to replace your amp without matching the calculations carefully.

Resetting the amplifier

After making calculations of AC voltages with the help of ohms law and processing the further steps concerned with the said procedure, you will be required to put back everything at the same place where you detached them earlier.

Make sure that the resetting does not involve any misplacement of the parts. Make sure that you have re-established the previous connection of all wires. Ensure the quality of the sound by playing a tune in the amplifier.

You have to be extremely careful while operating the tuning of an amplifier with the help of a multimeter. Do not harm the wires.
