How to Use 3.2 Ohm Speaker on 8-16 Ohm Stereo

The drawn-in higher ohms are higher when connecting a 3.2 ohm speaker with an 8-16 ohm stereo. In this instance, the 8-16 ohm stereo uses a lot more power than the connected speaker.

The important part is that it’s very simple to use the speaker with an 8-16 ohm stereo provided you understand their measurements and how they relate to each other. For example, their connection in watts and measurement of power.

Anyway, you don’t need to pressure yourself, as I have laid important details below that are a great beneficiary for you as the reader. I will show the use, frequently asked questions, and finalize the conclusion.

how to use 3.2 ohm speaker on 8-16 ohm stereo

Using a 3.2 ohm speaker on 8-16 ohm stereo, is quite simpler than you think as there are methods and procedures for you to follow to reach your goal. The first method ensures good connectivity and the second one uses good cables. Carefully follow the techniques for your work.

1. Ensure good connectivity

Ensure good connectivity

Ensuring good connectivity is one of the best steps to achieve a better connection, so follow the steps carefully.

  • Disconnect the connection from the power source

This acts as the first step before connecting any electrical gadget connection. The good part is that it keeps you safe in addition to you and your devices as an electronic shock can occur while connecting. Before you start your connection you will get the speaker 3.2 ohms and a stereo 8-16 ohms.

I advise you to also check the manufacturer’s specification before proceeding to the next step. The specifications help you understand how different speakers with different measurements in ohms get connected with the stereo of different measurements, so be brave on checking. 

  • Check the ratings in the speaker cable and the stereo to understand their miss-match. I guarantee this helps.
  • On the wire you will use to connect the speaker to the stereo strip, some 20 mm carefully and firmly twist the wire tightly together to prevent it from being loose.
  • Connect the gadgets by matching the polarities and ensure you have connected the correct cable in the speaker. Tighten the wires to the speaker for it to be firm.
  • Ensure to check the right terminals as the positive and negative ones should be checked with much keenness.
  • After the connection check, the speaker’s position sometimes causes inaccurate results.
  • Finally, you can decide to put your speaker at the same height as your ears to hear them effectively. At some instance, place it at a 30 degrees angle to get the sound you, the user, desired.

2. Power supply voltage

Power supply voltage

A 3.2 ohm speaker can complete a connection with 8-16 ohm stereo because stereos have less voltage, allowing more electric current to flow through them. The power created is too high because the ohms of the speaker are too low. Remember, a 3.2 ohm speaker is mostly preferred for car system stereos use due to their specifications.

To achieve the connection between a 3.2 ohm speaker and an 8-16 stereo, you should play at a moderate volume because if a high sound is applied, the steroid can blow away as it draws more electrical current.

It is good to work with a steroid with lower ohms than the speaker because it drives a lot of power current. A lot of voltage in the speaker enables high sound and volume, which also creates the quality of the sound.

Don’t forget the specification of the steroid and the speakers before purchasing as this helps you finish a good connection and damage your gadgets. 

3. Impedance

  • Impedance is basically how the speaker opposes the flow of current when it is connected to a stereo. It is good to check the speaker’s impedance range when choosing a speaker.
  • Inductance and capacitance mainly affect how impedance how, resulting in a change in sound frequencies. To acquire impedance, you should look at the electric current’s resistance and its inductance in the coiled wire.
  • The stereo supplies power to the speaker’s magnetic fields when exposed to it, creating sound. To connect a speaker with a stereo, you have to ensure the speaker’s ratings and the steroid match. This helps to enable power delivery and sound quality to be high.
  • Connecting a 3.2 ohm speaker and 8-16 ohm steroid are not compatible in connection because a speaker with lower impedance than that of the steroid, which becomes higher, can cause heating and even end with the damage of the system.
  • Crossovers are only used with the specified speakers because if not, in that case, the change in frequencies led by crossover affects sound production. Remember that having higher ohms gadgets does not automatically mean high sound quality and sound.

Frequently asked questions;

  • What is the difference between the speaker and steroids?

Both of these two gadgets are speakers. The only difference is that steroids act as passive speakers because they need external power, but in the case of speakers, they are active speakers because an amp is built inside the speakers.


Following the basic reasons I have given you in my article, I believe you can personally connect the asteroid and speakers. All the methods I have explained are of great benefit to achieve your connection so try to be careful when dealing with it.

In some instances, you can be in a position where you cannot complete the connection as you can face difficulties performing the tasks. The only problem is to call a technician who can navigate and solve any problem. More so is for the safety of your system.
