If you are looking for the best 4×6 speakers, the most important things to consider are the power handling capacity, sensitivity rating, and woofer cone material. I’ve summarized my favorite products below based on these features. Keep reading if you want to know more about why these features are so important.
Most cars are equipped with standard audio speakers that allow you to listen to the radio or even connect them to many gadgets, including your mobile phone or mp3 player. However, not all cars come with the most up-to-date audio systems, and their stock speakers are mostly not up to par. Since you’re reading this article, you may be finding the best 4×6 car speakers for your newly purchased vehicle.
Music, as we know it, is one of the significant necessities during driving. Most seasoned drivers know that driving alone can get way too tedious and monotonous, especially when you have to go long hours each day. It is too easy to fall asleep while driving, specifically when all you get to hear is the breeze whooshing against your windshield, and you’re in the middle of an empty highway. Heavy traffic may also be highly annoying, especially when you’re running late for work, or you’ve just gotten out of your daily nine-to-five, doing your best to reach home. Having an efficient car audio system can help keep you both awake and relaxed, allowing you to concentrate on your driving so that you get to reach your intended destination in no time safely.
While there are many car speakers available in the market, not all these speakers are compatible with your car’s model and size. Most of the newer car models do not have substantial extra spaces for those giant speakers you usually use at home. 4×6 speakers, on the other hand, get to fit tiny allocated spaces easily, and you can find a variety of brands and models to choose from.
To help you with your quest, I went through the different audio stores and found the best 4×6 speakers based on their performance. Read on and identify one—or two—that best suits your audio needs.

Thus, they are compatible with most stock car amps or, if your car doesn’t have one yet, you can easily find a car amplifier that’d make these babies work.
While their sensitivity rating isn’t as spectacular as other speakers I found, you can conveniently improve hearing capacity by turning up the volume notch.

NVX NSP46 N-Series – Best Audio Accuracy
Key Features
- Peak Power: 150 watts
- RMS Power: 50 watts
- Impedance: 4 ohms
- Frequency response: 90-20,000 Hz
- Sensitivity: 87dB
The problem with most manufacturers is that they do not provide you with the actual specifications of their units. As it happens, most brands merely estimate their units’ various capacities, which can be frustrating, especially when you want to find the exact 4×6 speaker pair for your car.
The NVX NSP46, however, offers you exact numbers starting from the number of speakers you get with the low price of $39.99.m In fact, this is the price for a single NVX NSP46 4×6 speaker. So, of course, you’ll need to multiply that twice if you plan to purchase a pair of these. Each speaker has an RMS power handling capacity of 50 watts that can reach 150 watts.
It has an impedance rating of 4 ohms and a frequency response range of 90 to 20,000 Hz. While it has an average sensitivity rating of 87 dB, this unit makes up for that by offering you clear and defined sounds. It produces a warm treble response, although it doesn’t do well with the lower-end bass sounds.
Nevertheless, it is incorporated with a silk dome tweeter and a polypropylene cone that ensures precise notes and rich feedback. This unit makes use of a high-temp KSV voice coil that permits a balanced distribution of current and a fast heat dissolution—this is a critical point to take note of as it is related to the safety precautions you need to take when using such small speakers that are highly prone to damage and overheating.
This unit is also incorporated with a nitrile butadiene rubber surround that further improves audio accuracy. Honesty and accuracy are a couple of serious ideals that the company makes sure of. Thus, they prefer to give their customers the actual number when it comes to the capacity of their units. You have to remember that a high standard ensures you that you are purchasing a product that completely performs just as you expect it to, and the NSP46 should be one 4×6 speaker alternative to consider.
| Pros • Honest manufacturer sales talk • KSV voice coil for balanced current and heat distribution • Accurate audio feedback • Warm treble response | Cons • Limited bass • Low sensitivity rating |
Skar Audio TX46 – Best Speaker Construction

- Peak Power: 140 Watts (Pair)
- RMS Power: 70 Watts (Pair)

Another from Skar Audio, the TX46 is a pair of 2-way coaxial speakers that have a combined peak power of 140 watts. They also have a combined RMS power handling capacity of 70 watts. While their frequency response range is pretty standard with only 80 to 20,000 Hz capability, these speakers are equipped with a high-performing silk dome tweeter that allows you to have superb audio quality. These speakers also use a copper voice coil and a TPE surround, which further aids in improving sound quality and stabilizing the system.
These speakers produce crisp, vibrant high notes and clear low notes. They can also manage loud volume levels and are excellent alternatives to most 4×6 speakers in the market. In fact, audiophiles will appreciate this pair for its capacity to produce top-quality sounds despite its low price and tiny size. Nevertheless, these speakers are limited in the sense that they do not handle midrange tones well. However, for a starter set, these speakers perform much better than the usual factory-installed speakers of most cars.
| Pros • Vibrant highs and distinct lows • High-quality construction • Can manage top volume levels | Cons • Limited midrange response |
What to Look for in 4×6 Speakers
It can become overwhelming when you are suddenly faced with a myriad of technical terms that leave you with the possibility of purchasing the wrong speaker. You need to understand some of the speaker terms you get to read so that you can identify the best 4×6 speaker—or speakers—for your car.
Sensitivity Rating
Sensitivity refers to the 4×6 speaker’s sound ratio concerning the power that it gets to handle. This element is measured in decibels (dB). Because most 4×6 speakers are merely developed to manage a low RMS power capacity, there is a need to provide them with a high sensitivity rating. By doing so, your speaker gets to have the ability to produce loud—and still solid—sounds even when you decide to turn up the notch. A 4×6 speaker must have a sensitivity rating of about 90 dB and have reliable audio feedback even at max volume levels.
Power Handling Capacity
In relation to a speaker’s sensitivity rating is its power handling capacity. This element is measured in watts. Most car stereo or radio units are low-powered ones. Hence, you do not really need high-powered speakers to maximize their performance. Nevertheless, your speakers must be able to match the power capacity of your amplifier for them to work effectively.
Woofer Cone Material
Car speakers are typically smaller in comparison to your home studio-bound ones. Thus, their woofer cones are comparatively smaller as well. Car speaker manufacturers attempt to transcend this limitation by trying out different woofer cones materials to improve woofer sound feedback deftly. Hence, the better the material and built of your woofer, the more able it is to produce clear and distinct lower-end tones. When purchasing 4×6 speakers, you need to pay attention to their woofer quality. This permits you to have speakers that capably offer not only superb higher-end tones but lower-end ones as well.
Price
Most 4×6 speakers do not cost much. This doesn’t mean, however, that you can just pick some generic, low-priced unit if you want to replace your car’s stock speakers. The need to read in-depth reviews of your candidate option is beneficial as most customer comments offer you excellent insight into the different capacities of each speaker unit. Bear in mind that price doesn’t always equate to quality.
Brand and Model
Likewise, various brands offer a plethora of 4×6 speakers to choose from. While most go-to brands like Pioneer, Rockford Fosgate, and Skar Audio offer you high-quality alternatives, some of the less known manufacturers offer premium-grade units as well. It would be best if you had proper discernment so that you get to obtain the best speakers irrespective of model and brand.
