They are an excellent OEM upgrade that are designed to provide clear sound and full bodied bass for any genre of music. However, if you are willing to invest into the ultimate 6.5 inch speaker setup, the Focal PC165F speakers are the best alternative but they do come with a premium price tag.

The factors that we considered included their peak power and RMS ratings, construction, hardware included, warranty and value for money.

In terms of the performance of car speakers, the main ratings you want to pay attention to is the peak power and RMS. The peak power refers to the maximum power the speaker can handle within short intervals whereas RMS (Root Mean Square) is the continuous power that the speaker can handle. Premium quality speakers often have a higher RMS, which provides a better indication of its ability to produce superior sound quality.

Below is a list of the best car speakers that are direct replacements to OEM speakers and produce excellent sound quality and bass.

How We Rated The Car Speakers

As we own many classic/old cars, we have performed multiple speaker upgrades over the years due to the speakers providing poor performance or simply breaking.

Therefore, along with our own experience, research and considering multiple factors, we were able to create the list of recommendations above. The factors we considered included their peak power and RMS ratings, construction, hardware included, warranty and value for money.

Conclusion

Upgrading your car speakers is relatively easy and it has the ability to completely transform the sound inside of your car. When deciding between the different car speakers, we advise that you choose a higher RMS rather than a higher peak power rating. The RMS rating of a speaker provides you with a better indication of its sound quality. This is important because many brands will often only state a large peak power rating but this isn’t a true reflection of the speaker’s quality.

The recommendations above are all suited for 6.5 inch mounting holes but most brands will offer alternative sizes if needed. To avoid disappointment, we advise that you remove your existing speakers to find the exact size required.
