- Best Car Speakers: Common Speaker Terms & Ratings
In most cases, the speakers that come in factory stereos don't meet consumers' expectations for quality, longevity and most importantly performance. Finding an all-around Best 5.25in Car Speaker that will significantly boost your stereo's performance while maintaining a high expectation for quality, dollar value and most importantly sound reproduction, can be difficult and time consuming. A good pair of speakers will allow you to turn up the volume while lowering distortion and bring true sound to your music. If you're unsure whether your car will fit a 5 1/4″ speaker, check out our car speaker fitment guide to confirm the speaker sizes for your year, make and model.
Also referred to as “separates”, component speakers have two separate speakers that emit different ranges of frequencies and sounds. The woofer, or the larger speaker, emits the lower to mid range frequencies while the tweeter, the small speaker, covers the very high range frequencies and noises. Separating the tweeter and woofer allows for clearer sound with less distortion. Pair them up with one of the Best Car Stereos on the market, and you'll find yourself reluctant to leave your car when a good tune is playing.

Focal PS 130F Quick Review
The French engineers at Focal have squeezed all the best parts of their mind-blowing 6.5” speakers into these stunning 5” components. The innovative flax cones do more than just look good, too. In fact, the flax fibers create hollow chambers and an increased surface area for tight, clean sound reproduction. The flax cones are known for delivering smooth, precise sound with incredible mid-range frequencies and good bass.
The speakers combine this innovative Flax technology with Focal’s renowned inverted dome tweeters to produce the best sound performance that a 5.25” component speaker system can produce. The tweeters are supported with a Poron suspension for long life. They work like a small woofer by dispersing high frequencies over a broad area, making it possible to generate crisp and clear high-frequency sound without distortions.
The included crossover is prewired for two-way installation but can be converted to a three-way crossover for adding additional speakers. The tweeters include mounts for surface, angled, and recessed installation. Aluminum baskets and butyl surrounds give these speakers the toughness to handle pro-level power.

3. Best Factory Upgrade: Hertz ESK 130.5
Hertz ESK 130.5 Quick Review
Hertz might not be the first car audio company that comes to your mind when you shop for a great factory replacement component system, but it should be. We first became familiar with Hertz in the 2000s and fell in love with the Energy and Hi Energy series of speakers and subwoofers. The Energy series is a great option for a simple upgrade to a factory system, or a perfect choice for a performance system if you want it to be. The ESK series of 5.25” components feature water-repellant pressed paper cones and butyl-rubber surrounds for durability and crisp sound recreations.
The Italian-made speakers are incredibly well-made. They are capable of handling a peak of 225 watts, more than enough for any factory stereo out there. While many companies have started using exotic materials, Hertz simply makes the best paper cone speaker around.
- Features a large magnet that helps improve speaker control
- High quality materials
- Incredible sound system
- The speakers come in custom shapes and sizes
- The large magnet makes it difficult to install the speaker in vehicles with limited space
4. Best Convertible Component Speaker: JL Audio C3-525
- 2-way 5.25” components with 1.2” removable or mountable tweeter and two crossovers
- Frequency Range: 48-25k Hz
- Power Handling: 75 Watts RMS/ 225 Watts Peak
JL Audio C3-525 Quick Review
Sometimes, a coaxial setup fits the bill, while other times, a separate tweeter can help round out your sound. But what happens when you have one but want the other? If you buy the C3-525 5.25” convertible component system, it’s simply a matter of sliding the tweeter out of the woofer and mounting it where you want.
JL Audio built these with tough-as-nails mineral-filled polypropylene cones and injection-molded baskets for a rugged package. The oversized 1.2” removable tweeters can be flush or surface-mounted for versatility.
JL Audio engineers packed all that strength in for a reason. These components are rated for up to 75 watts RMS, so show no fear throwing some serious power at them. In fact, JL Audio claims you can put up to a 150 watt per-channel amp on these speakers.
The removable tweeter is obviously the trick feature here, and JL Audio made sure that the little speaker was silk-domed and capable of handling as much juice as possible.
- Removable, oversized tweeter
- Broad frequency range
- Durable Speaker
- Higher cost than other systems
- Amplifier recommended
- The interface between the removable tweeter and the woofer may become damaged and stop working
5. On a Budget Pick: Rockford Fosgate R152-S
Rockford Fosgate 152-S Quick Review
You would expect a component set at this price point to sound a lot like something you bought at a swap meet. In a surprise move, the folks at Rockford Fosgate have put together a package of budget-friendly components built around the same technology as the up-market Power Series -for less than half the price.
The Prime Series components use a cost-saving mica-injected polypropylene cone and a foam surround, but these speakers produce a warm, rich, and full sound without reverb. In fact, these are among the very best component speakers for a direct factory upgrade. The package is rounded out with a set of ½” mylar-balanced dome tweeters and inline crossovers that are intended to simplify installation.
It is hard to beat the built-in quality of Rockford Fosgate speakers. The Prime series component speakers carry a 1-year factory warranty. These speakers have been a popular upgrade since 2016 for good reasons.

Best Car Speakers: Common Speaker Terms & Ratings
When comparing and choosing the Best 5.25″ Component Car Speakers on today's market, CarAudioNow takes into consideration several key criteria: Lets define a few common criteria and terms that are compared when rating a speaker:
Power Handling: Power handling is the measurement a manufacture gives to rate how much power a speaker can handle and operate at. It is given by two measurements, RMS and Peak (or MAX). RMS Power rating is the amount of power the speaker handles continuously, while the Peak Power rating is the amount of power a speaker can handle in short bursts. When comparing speakers, RMS Power is the more relevant and important rating to look at.
Sensitivity: The speaker sensitivity rating is a measurement of the amount of sound the speaker will emit from the power it’s given. The higher the sensitivity, the more efficient the speaker is with the power it’s given. For lower powered systems, you want a higher sensitivity rating. For a higher powered system, you want a lower sensitivity rating. Lower sensitivity rated speakers are meant to handle higher power.
Frequency Range: Frequency range is the frequencies that the speaker emits sound at, measure in Hz. Normally they are given from a low frequency to high, for example: 20 – 22,000 (22k) Hz. This measure how low and high the speaker can actually emit sound at.
Speaker Design and Materials
Woofer: The speaker woofer can determine the responsiveness, and quality of the speaker. The stiffer and more lightweight the material used, the more effective the speaker is. Polypropylene is a very common material used for the cone, as well as woven fabrics such as kevlar. Aluminum and titanium are also used in higher end speakers.
Woofer Surrounding: The woofer surround also is an important aspect of the speaker system and effect the sound as well. Durable, lightweight, and free moving materials are used to allow the woofer to move with as little energy possible. The material is essential for a long lasting and performing speaker too. As speakers get older and used, humidity levels and wear-and-tear can crack and even break the surrounding of the woofer. Rubber surrounding is typically the most long lasting an high performing material. Foam an cloth surroundings are found on less expensive component speakers, with lower performance and shorter life spans.
Crossovers: When you purchase a component car speaker system, a crossover is almost always a part of the package. External crossovers are typically used to lessen the amount of distortion a speaker might have by separating the frequency inputs. Signals can cross through coated wiring and cause distortion, so an external crossover system will limit this.
