This Month I Tried Dozens of 6.75 Car Speakers for Bass So Let’s Find Out Which One is Roof-Smashing

Choosing the appropriate 6.75 car speaker with decent bass can take time because you must select a single product from many competitors.

As an audiophile, I have always been cautious in choosing a product that has louder volume, richer bass, durable material, and is budget-friendly at once.

For this purpose, I have tried and tested different speakers from different brands, and in this article, I will show my top eight picks. 

What makes a good 6.75 speaker should be the following question in your mind.

To better understand the speaker you intend to buy, please go through the buying guide. This comprehensive guide will enlighten you about the different aspects of 6.75 car speakers so you can have a more refined choice.

Buying Guide for 6.75 Bass Car Speakers 

Before replacing your car’s OEM with 6.75 speakers, you should know the most common terminologies of speakers, like power handling, sensitivity, woofer and tweeter material, impedance, and the type of speakers. 

Sensitivity of Unit

When you apply a single watt of power to the speaker, how loud sound it can produce is termed sensitivity.

To better understand this phenomenon, for instance, if the sensitivity on the specification sheet is mentioned as 88dB, it means when you give one watt of power, it will produce an 88dB loud sound. The higher the sensitivity, the lower the required power to produce sound.

So, a higher-sensitivity speaker will work efficiently with a low-powered car stereo. If you take my recommendation, a 6.75 speaker is viable if the sensitivity is above 90 dB. 

Peak Power Handling

These days, most cars are equipped with high-powered stereos capable of producing high wattage.

In this regard, your speaker must have a higher power threshold to absorb without damage. This power is called peak power handling, indicating the speaker’s compatibility with low and high-powered systems.

Knowing the power handling of the product you intend to buy, and your vehicle’s current power system is essential.

In addition to power handling, another important indicator is the RMS rating, which means the continuous power a device can take with excellent performance.

It is measured in watts, and a speaker having below 60 watts RMS value is considered to be used with low-powered stereo, and anything above 60 watts is good to go with high-power audio regimes. 

Impedance 

Out of the applied power to your speakers, it won’t utilize all the power; instead, it will resist the power.

This resistance is called the impedance of a speaker, measured in ohms. It is vital to know about the impedance of your product because it lets you see the load to be placed on your amplifier. 

Having a modest impedance is mandatory because, with very low impedance, loads of current go through it, potentially overheating the internal components and leading to permanent damage.

Moreover, if the impedance is very high, it will draw more power resulting in weak and muddled output. The standard impedance in a 6.75 speaker is 4 ohms with a margin of 1 ohm (+-1).

Build Material: Woofer and Tweeter

The build material of woofer cones and dome tweeters is of utmost importance. It equally affects the sound quality and durability of the unit.

As the woofer cones have a hectic job of vibrating for the emission of bass frequencies, their material must be lightweight to perform its task efficiently.

Moreover, it has to be rigid and stiff to withstand these vibrations. Usually, a synthetic polymer called polypropylene is used in woofer cones; this material has the properties of rigidity and lightweight simultaneously. 

On the contrary, the dome tweeter is either hard or soft. Soft tweeters are responsible for smooth sound and usually build textiles like silk.

The rigid tweeters are constructed to produce highs that cut through the mix as they are made of metal, graphite, or ceramics. I like using soft tweeters as they are economical and perform well.

List of 7 Best 6.75 Car Speakers for Bass I Like
