"We live it, breathe it and make it kick" is the slogan of Kicker, which is founded in 1973 in the States. These guys know how to make speakers kick and feel the power of bass.

43DSC69304 is a great alternative. It has clear sound at mids and crisp at highs. However, they seem to be lacking some kick in the lows. If you need to get decent performance from them, you need to get an amplifier and tune it up above the RMS level, which can be dangerous for its endurance. RMS level of these speakers is similar to others in the list, by peak power handling is way below relative to others. Maybe this can be an indication of its material performance, which eventually prevents you from getting a thumping bass sound.

Anyway, this speaker has 92 dB of sensitivity and it can increase the sound intensity up to 110 dB at RMS level which marks this one as one of the loudest speakers in this list. Generally liked it, however, we strongly suıggest for using subwoofer is you install them.

How to Select Best Speaker for Yourself?

You may be overwhelmed by the technical terms listed in our article if you are not so familiar with audio systems. No worries, we will explain all terms in here.

Before starting our guide, first of all, think about your needs. Do you want to make a high-end audio system for yourself? Or do you want to just replace your speakers and will it be enough for you? It is totally up to you.

What is "Frequency" Means?

Each soundwave has its own frequency. A perfect human ear is able to interpret soundwaves having between 20 - 20.000 Hz. This is so called the "audiophile grade". Most of us will easily hear sounds between 30 - 16.000 Hz.

Speakers are able to reproduce high frequencies and each of them can reach up to 20.000 Hz without any problem. Regular speakers can have a hard time to get as low as 20 Hz, depending on their size, design. For this manner, subwoofers are produced which is dedicated for 20-100 Hz.

Low-frequency sounds are bass. High frequencies are the crisp sounds. We consider a range of 30 - 20.000 Hz well enough for car speakers.

What does "Way" mean in a car speaker?

Way represents how many drivers located in a speaker. Drivers are the sound reproducer parts of speakers when they are given power.

In this article the most common speaker type you see is 3-way. In these speakers; there are woofer for low sounds, tweeter for high sounds and mid-range drivers for the sounds between. 3-way speakers have an internal crossover, which dedicates each speaker to certain frequencies. You may also want to check our what is 2-way speaker article for getting more information.

In the same brand, the increase in the number of ways in a speaker indicates a better sound performance and higher quality. For example, Pioneer TS-A6990F is a 5-way speaker. If you click and check you may find a 4-way brother of it in 6x9" size as it is. If you compare them, you may find that 5-way TS-A6990F will make you feel you are listening to a better sound, which has deeper basses and high-quality mids, highs. 

What is the "Power Handling" of a Speaker?

Each speaker has its values for how much power you can run them on. You will find two values commonly, "Peak" and "RMS" values.

Peak values indicate how much power a speaker can handle before they blow off. So, you may want to stay away from there.

RMS value is, on the other hand, is a power you may consistently supply to your speaker without damaging it.

Do I Need an Amplifier?

As a stock build, your car will not have an amplifier and because it does not need one. Cars power their speakers from their head units and they provide power up to 50 watts.  

If you are going to buy a speaker that has high RMS values, to obtain the best results from them you will need an amplifier. This is not a must of course, but decent audio systems have amplifiers attached to them.

If you want to add a subwoofer to your system, adding a power unit and an amplifier will be necessary.
