Thus, it’s not an easy task when it comes to purchasing the best car speakers. That’s why this article was written.
There are 5 elements of a car speaker that you should consider before going to the car accessories shop which are sound quality, impedance, speaker sensitivity, power handling ability and finally price.

5 factors


Sound Quality

The sound quality of a car speaker depends on how sharp the notes and basses will be at different volumes. In order to quantify this criterion, audio specialists has suggested the Total Harmonic Distortion (TDH) which is the measurement of how good the speak is capable of interpreting the audio languages stored within a disc or a flash drive into sound. The bigger the TDH the more distortion. It’d better choose a speaker with TDH figure ranging from 0.05% to 0.1%.

Signal to Noise Ratio means the proportion of quality sound to noise. Simply put, the higher the ratio the better the sound quality. You should choose a speaker with this signal within the range from 90 to 100.

One more crucial figure is the Headroom in case you want your speaker to well perform when it comes to short bursts. The bigger the Headroom the better.


According to Wikipedia, Electrical impedance is “the measure of the opposition that a circuit presents to a current when a voltage is applied”. In other words, the figure Impedance measures how much current that a car speaker can absorb. The higher the impedance the less current the speaker takes in. Most of speakers’ impedance is 8 ohms. A high-end one is 4 ohms but a little pricey. However, you will need a exceptional amplifier to maximize the potential of this speaker.

Speaker Sensitivity

This is a very important figure that every speaker purchaser should consider because the more sensitive a speaker the less power it requires from the amp to sound great. However, a speaker with high sensitivity is very pricey.

Power Handling Ability

This figure indicates the maximum power a speaker can suffer without being bursting. You should find speakers with a power handling RMS rating ranging from 120 watts per pair to 360 watts per pair.


A good car speaker isn’t cheap. Therefore, make sure you invest in the right pair of speakers which fit your space as well as sound needs.
