What To Consider When Looking For The Best 4×6 Speakers

Before you do any shopping, there are some crucial factors you will need to consider. It is important you gather some details about the speakers that are already in your car. Some of the details and factors to consider include the following;

#1- Coaxial Or Component Speakers  

The argument about which one to go for between component and coaxial speakers is complicated. There is no simple answer to that argument as it all depends on many factors.  Coaxial speakers are the best when it comes to budget and installation. They, however, have average sound quality.

If you are a high quality music lover and you want the best quality from your speakers, component speakers might be the best choice.  They offer the best sound quality and staging. They are, however, expensive and difficult to install.

#2- Power Handling

Another key feature you will need to look at is the power handling capabilities of the speaker. Is the speaker able to handle the power being input by the head unit or the amplifier? This means that you will need to check the ratings of your amplifier or the head unit before you go for any speaker. If you are planning to install the whole system, then it is good to go for the head units and the amplifier first.

What is power handling? It refers to the level of power one can pump through the speakers measured in Watts. The most given power handling ratings are RMS and the Peak or the maximum value. The important value is the RMS (Root Mean Square). Make sure that it is within what the amplifier and the head unit can supply.

#3- Configuration

Most of the people get mixed up between getting 2-way or 3-way speakers. So, what is the difference between the two and which one should you go for? First, what is speaker configuration? A speaker’s configuration is the number of drivers a speaker has.
The 2-way speaker has two drivers which are a woofer and a tweeter. A 2-way speaker has more bass combined with mid bass and separated high frequencies. A 3-way speaker, on the other hand, has 3 drivers.
These are a woofer, a mid-range driver and a tweeter. It produces separate bass, mid frequencies and high frequencies. A 3-way speaker will sound better than a 2-way speaker

#4- Sensitivity

Another key factor to look for if you are looking for the best 4×6 car audio speakers is sensitivity. Sensitivity is how louder a speaker will get if supplied with certain power. A speaker with higher sensitivity means it will require less power to get louder while that with low sensitivity speaker will require more power. Most standard speakers have sensitivities between 88dB to 92 dB.

#5- Speaker Build quality

One of the major reasons why you are upgrading is to get good quality speakers. Most of the factory speakers do not have quality materials. They, therefore, degrade over time.  You need to ensure that you reap the most from your upgraded speakers. One of the ways to do that is by buying a speaker made with the high quality material.

Some of the materials to look at are the surrounding material. Rubber surround is the best for durability. For cone materials; polypropylene that is mixed with mica is the best when it comes to cone materials. Metal-coated synthetic fabrics are the best for durability and long-time performance.

#6- Compatibility

Compatibility plays a crucial role in getting aftermarket speakers. Before you spend any cash on buying your new speakers, you will need to find out if the potential speakers are compatible with your car. Are they made in a manner that they can fit into the factory speaker points of any car without any modifications?

#7- Cost of the speakers

Determine your budget before you do any purchases.  This will ensure that you remain in the range of your budget. You can also change the budget in favor of the best speakers.

Still, on sound production, it has a frequency response of between 90Hz to 22 kHz. This means that you will hear most of the mid bass and less sub bass sounds.

This means that it has excellent loudness even with low power input.

Regarding installation, it is fitted with a flex fit basket which is compatible with factory speaker locations. The frame uses slots, unlike most speakers which use single screw sized holes. What this does is that it allows you to do some adjustments as you install the speaker in place. There will be no need for more holes.

These drivers allow a wider dynamic range of deep bass, wide mid frequencies as well as smooth and crisp high frequencies. The woofer consists of a wide rigid multilayer mica matrix cone structure for wide dispersion of sound.  

On the woofer are a midrange driver and tweeter which are designed to deliver a wider range of mid to high frequencies. The speaker consists of a 200 Watts max power and a lower 30-watt nominal power. This means that even at a low power supply, the speaker will still respond well.
