A car’s audio system is always one of the most challenging features to select. Various audio systems exist, so make sure you choose the best one for your vehicle. Well, no worries. Here is an in-depth guide about the best 2 ohm 6.5 component speakers.

Impedance is the measurement of how much a speaker can resist the current of power from the device it is connected to. The main difference between all types of speakers is their electrical resistance. A 2-ohm component speaker has less resistance. A 6.5 component speaker has a small cone area, and therefore the bass frequencies are lower. This results in low-volume sound. However, you can enjoy the quality sound at an affordable price. 

Depending upon how much you want to invest, 2 ohm 6.5 component speakers can come at a price as low as $100. But, you can spend 1000 bucks too.

Buying Guide

Frequency Response

The frequency response of 2 ohm 6.5 component speakers range from 50Hz to 20kHz. The values show low and high frequency capabilities of speakers. Nevertheless, the frequency response varies with the model.


Sensitivity is how efficiently a speaker converts power into sound. Typically, the sensitivity range of 2-ohm 6.5 component speakers is observed to be 85dB to 95dB or even higher. It means speakers can produce loud and clear sound with minimum power input. 

Power Handling

The power handling of 2 ohm 6.5 component speakers depend upon model and brand. It’s common to find a 2-ohm 6.5 component speaker handling the power of 50 Watt RMS and another handling the 150 Watt RMS. 

Some Elements Of Car Speaker Design

Woofer Material

Want to listen to music at low frequency? Woofer material is responsible for producing low-frequency sound. So, give special attention to them if you’re planning to replace your sound system. Paper, aluminum, and carbon fiber are some woofer materials used in sound systems.

Tweeter Materials

Tweeter materials are responsible for giving a louder and clear sound of high frequency in a car’s speaker system. Synthetic fiber, metal, and ceramics are used in tweeter diaphragms. 

Surround Materials

Other than tweeter and woofer material, surround material is also important in a car’s speaker design. Foam, rubber – butyl rubber, and cloth are some surrounding material which attaches the speaker cone to its frame to provide stability. 

Pivoting Or Swiveling Tweeters

Pivoting or swiveling tweeters are an important component of the speaker system. These tweeters are adjustable and are directed towards the preferred listening position of the listener. They are rotatable and you can customize the sound too, pretty amazing! 

Tweeter Attenuation

Tweeter attenuation or tweeter adjustment allows you to adjust the output level of the tweeter. Therefore, give the option to fine-tune the balance between other drivers of the speaker system. It allows you to customize the sound and acoustic characteristics of your vehicle. 

Bi-amping capability

The bi-amping capability of a car’s speaker allows separate amplification of the woofer and tweeter. Bi-amplifier enable the use of a separate amplifier for each driver, thus improving the driver control.

Frequently Asked Questions

Do 2-ohm 6.5" component speakers need separate crossover networks or are they built-in?

It depends on the model you’re using. Some speakers come with built-in crossover networks while others require a separate crossover. It’s better to check the specifications of a product if you’re planning to install a component speaker or already have to know whether it has an in-bult crossover network.

Differences between 2-ohm and 4-ohm 6.5" component speakers?

A 2-ohm and 4-ohm 6.5" component speakers have several differences in terms of impedance and power handling, which affects the sound quality and amplifier’s compatibility. Depending upon these characteristics both component speakers differ for their durability, sound quality, and price.

Would it be possible to connect 2-ohm 6.5 component speakers to a high impedance amplifier?

It puts extra pressure on the amplifier and they get overheated, which results in damage. Additionally, the sound quality may also get affected. So, it’s not recommended to connect 2-ohm 6.5 component speakers to a high impedance amplifier. It’s best to take advice from a manufacturer or some experts.
