Choosing Quality 4x6 Car Door Speaker

Following are some features you need to consider when selecting the best 4x6 car speakers:

Sound Quality/ Audio Performance

The best sound systems reproduce sound accurately; this sound quality is linked directly to its sensitivity or efficiency, which is the measurement unit of sound (dB) in ratio to the supplied power. If your factory fitted speaker has lower sensitivity, you can install a high sensitivity speaker to enjoy better sound quality.

Additionally, decent audio performance is reliant on frequency response; this is the range of audible frequencies that the speaker can produce. The range spans from 20 Hz and 20 kHz – so ideally, you need a speaker that can operate on both high and low-frequencies without much deviation.

Compatibility & Amplification Requirements

Matching speakers with your car’s stereo system is absolutely vital for top-quality sound. A good audio system unites all the different elements like speakers, receivers, etc. to ensure excellent audio. Car speakers function on a specific range of amplifier power. It is important to ensure this power specification is compatible with your audio system for improved sound quality.

Ease Of Installation

Before purchasing 4x6 component speakers, you need to gather some information about the factory fitted speakers that you are going to replace. This will arm you with basic knowledge of whether the new speakers will easily fit in the given space or not. You can always take out the old speakers and measure them, or many stores also provide configurations and size specifications for your vehicle based on the make and car model.

Build Quality & Design Aesthetics

A comparison between available 4x6 car audio speakers will tell you about the diversity of materials used in their construction. For instance, the cones located in each driver may be made of aluminum, paper, polypropylene, polymer, etc. As the function of the cone remains the same – that is to create sound waves by pushing air – you might be wondering at the variety of materials.

The cones work like a piston to push air, but some of the softer ones bend and flex at specific frequencies; this distorts the sound. In other words, a more rigid material based cone is better. This is just one illustration of how much impact the construction and materials have on sound quality. The fact is, everything from the glue to wires in a speaker affects the sound – this is the reason why speaker manufacturers pick each component with care.

Power Rating/Handling

Two key components you need to consider before buying a new set of speakers include peak power rating and RMS (Root Mean Square) wattage. The former indicates a speaker’s maximum power handling capacity in short bursts, while the latter signifies the amount of power it can withstand regularly.

According to manufacturers, if you need to protect your speakers, you should pay attention to the RMS rating. You should consider choosing a higher RMS power rating if you have a robust external amp which requires more powerful speakers to match its output. Generally, using low powered speakers will do more harm than good and reduce the life of the speakers.

Price & Warranty

An all-important point to consider before buying new speakers is its price. You can gather all the information about your preferred speakers and then compare their prices.

This can help you finalize a suitable product that fits your needs and doesn’t burn a hole through your pocket. Additionally, check whether a warranty covers the speaker or not, if it is, then it is important to read all terms and conditions thoroughly to check what is included and how long it will remain valid for.

How Car Speakers Work

Speakers are much like air pistons that move back and forth depending on the electrical signal provided, and this movement translates into music for us. Simply put, amplifiers produce alternating electrical waves that turn the voice coil into a magnet. This electromagnet is either attracted or repelled and causes the speaker cone to move, which results in sound.

4x6 speakers are non-expensive, small-sized options mostly fitted in the front of a car. These speakers, with their excellent bass, add a punch to your audio and sound system.


Benefits of Upgrading Your Car Speakers

Your car speakers are an essential aspect of the sound system; almost all auto enthusiasts demand excellent sound quality for a better driving experience. So, the first thing you want to do if you want an impressive sound is to replace the factory speakers as most of these are not competent, to begin with, or wear out over time.

You can get better speakers without burning a hole in your pocket while also enjoying the top-notch sound. Good quality aftermarket speakers come with better sound and superior construction as compared to factory-installed ones. This enables them to produce various wavelengths of sound accurately to provide crisper and clearer audio.


Coaxial (Full-Range) Car Speakers vs. Component Speakers

Most factory fitted car stereo systems contain coaxial speakers; simply put, these consist of all components combined into one structure. Also, full-range systems are easier to install and come in various sizes that mount effortlessly in factory speaker fittings. Bear in mind; these systems are not that impressive when it comes to sound quality.

On the other hand, component speakers have separate drivers that can be mounted at various locations inside your car. These types of systems are generally made of finer materials and present a better overall listening experience.


Installing 4x6 Car Door Speakers

Here's a list of things you may require to install 4x6 component speakers:

  • Some basic tools including screwdrivers, wrenches, wire cutter/stripper, soldering iron and solder, crimping tool, panel removal tool, connectors and drill set
  • Retaining clip remover
  • Electrical tape
  • A file
  • A hobby knife

If you have all these tools, let’s begin with the installation process:

  1. 1
    To safely install new speakers, it's crucial that you disconnect the negative terminal of the battery. Remember, the open doors can drain your battery and leave you with no juice. Additionally, it can also protect you from dangerous short circuits.
  2. 2
    Remove all the components within the 4x6 speaker box. This may include speakers, wire, mounting screws, clips, crossovers, tweeters, tweeter mounting hardware, and an instruction leaflet. It is important to decide where you want to install your tweeters and what type of mounting you would like (flush, angled, or surface).
  3. 3
    Now, remove your old speakers. For this, let’s take the example of the Ranger’s factory-fitted speakers that are mounted in the doors.

Firstly, pull out the window crank; some vehicles require a window crank removal tool, but for this, you can utilize a panel tool to pry the cover. After this, the crank can be removed with a Torx T-20 screw. Then, you should remove the Philips screws and also the door cup – at this point, the door cover should slide right off.

  1. 4
    As the factory speaker is mounted with the help of four Philips screws, the speaker can be cranked using a flat head screwdriver after removing these four screws.
  2. 5
    Now, we can prepare the crossover by stripping its input wires and connecting them with Crutchfield wiring harness. You can either solder these two together or use connectors to join them.
  3. 6
    There is space for 6”x8” speakers in the front door of the 1996 Ford Ranger. Similarly, many vehicles might have different spaces. To adapt to this, you can use a Crutchfield speaker bracket to mount your woofers in the given factory opening.
  4. 7
    The next step will be to angle-flush mount the tweeters by first selecting the right position and then drawing an outline using the tweeter cup. Then, with the help of a drill, you can cut out a hole and trim it using a knife.

Note: every manufacturer provides a different system for mounting the tweeter.

  1. 8
    Then, you finish the wiring by attaching the woofer and tweeter to the crossover. Afterward, put the door panel back on the door. Additionally, you can put the crossover between the door frame and door panel and replaced the screws, pull cup, and window crank.

Once this is done, all you have to do is sit back and enjoy our music and crisp sound quality.


Tips to Better Car Audio Quality

Working on your car's audio quality is more like a journey rather than reaching your required destination. It is a process that you can keep adjusting and tweaking along the way.

Although a quick fix would be to buy the best available hardware, that would require you to pay considerable money upfront. Another way to go about it is to upgrade your built-in speaker and make a few adjustments here and there – with this you should expect the quality of your car’s audio to improve drastically.

Ironically, people expect these upgrades and adjustments to include an improved head unit as compared to your factory one or buying a subwoofer. But you can achieve better sound quality by just improving the environment in your car and getting rid of as much as external interference as you can.

Here are a few steps that can help you achieve this:

  • Remove your factory speakers as these usually aren’t that good to begin with. Replace them with aftermarket speakers, but keep in mind that they should be of the same dimensions as your factory speakers and compatible with your built-in unit
  • An upgrade in your head unit would do you a lot of good with regards to your sound quality. Usually, factory head units have an auxiliary connection that reduces the sound quality from its input. Having a head unit with a USB connection would improve sound quality drastically.
  • Adding certain components to your sound system is seen as an increment, such as an amplifier, as it allows you to slot in better speakers.
  • Playing sound from a high-quality music file, a compressed file would reduce the quality of your sound output.
  • Decrease the volume of noise coming in the car with soundproofing material such as Dynamat into your door panels.

Accessories for 4x6 Car Speakers

  • Grille/Grille Covers:
    Usually found in consumer and industrial speakers, this is mounted directly over the speaker with either a rigid or soft grille. Its primary function is to protect the speaker and the driver while allowing sound to pass through.
  • Speaker Brackets:
    Used to mound speakers onto an area that you prefer. They are useful because they allow you to fix your speakers properly and lend some much-needed stability.
  • Speaker Adapter:
    4x6 to 5.25 speaker adapter: These would fit in any Jeep from 1997-2006, and examples include Wranglers, Rubicon, Unlimited, LJ and TJ. It also aids in the adaptation of 5 1/4th speakers on your previously installed 4x6 speakers. They are durable and helps you in angling your speakers in an upright manner for better sound.
  • Speaker Box:
    These boxes come in handy when moving single units, but its basic function is to make sure the sound waves from the rear end of the speakers do not interact with the sound waves coming from the front.
  • Speaker Baffles:
    Installing speaker baffles helps you to keep your speakers clean and increases their life, although its primary function is to assist in reducing the panel to frame resonance by being tightly mounted around the speaker.

Frequently Asked Questions

What determines the sound quality of car speakers?

The frequency range can determine the quality of your car speakers; generally, a wider range of frequency means better quality as it provides a better sound output. The optimum range would be 20000 Hertz, while the lowest it can go is 10 Hertz.

Another measure of quality can be the Total Harmonic Distortion, which is basically the translation of sound from the audio file. Anything below 0.1% THD means that the speakers are of good quality, even though the usual value varies between 0.05% - 0.08%, which also implies a clean sound. 

You can also determine the sound quality through speaker impedance – this tells you how much power your speakers can draw. The standard would be 8 Ohm while 4 Ohms, which is great – but also more expensive, especially since you will require a good quality amplifier to get the most out of them.

Lastly, the headroom is the calculation of how much your system can produce in short bursts. You can take the example of a good home cinema sound system where you feel a jolt or vibration during explosions or gunfire from an action movie. The same is the case with your car speakers; if you feel any jolt or vibration, it means that your speakers are of good quality.

Where is the best location to place these car speakers?

For most of us, the dash, the doors, and the rear deck are the prime location as they have already been set from the factory. But once you opt for a custom upgrade, then the kick panel is known to be the best location. This is the area under the dash in the far left and far right corners of the car's interior. While some users might not be comfortable with this placement, it has to do a lot with the time-alignment. What this means is that the speakers must be placed at an equal distance from you so that the sound can reach you at the same time from both ends.

Do car speakers need to be broken in?

Not really – there is no need to play music on your speakers at half the volume to help ease into the process. The ideal way would be to play your music with a more comprehensive dynamic range, and after about 100 hours, the speakers would break-in. Although there is certain gear that can help you with this, it is a costly option and something that really isn’t necessary.

What are the best rated 4x6 car speaker brands?

Rockford Fosgade, Pioneer, Polk Audio, Boss Audio, and Kicker are some of the top rated 4x6 car speaker brands today.

Where is the best place to buy these 4x6 speakers?
