If you place them in the original location of the speaker, the dimensions and diameter, as well as the depth, are important.
Also, the diameter will determine the sound power, and the larger your vehicle is, the more you will benefit from selecting large-diameter speakers.
Speaker power – The indicated power is a vast subject, it is more of a commercial argument than a technical one, as this notion is very vague:
Often, it is the maximum power that is mentioned, which is not representative of the quality of the speakers.
Looking at the technical specifications, you will also find the RMS (Root Mean Square) power, which is the effective power and which is a relatively reliable comparison element.
Number of speaker channels – As described above, it allows the 2 or 3 membranes to be distributed throughout the vehicle, reproducing bass, treble and midrange for better sound reproduction.
Speaker Sensitivity – Sets the maximum number of decibels emitted.
Speaker frequency responses – These correspond to the minimum and maximum frequencies delivered.
Car speaker amplifiers – To optimize the sound, you can add an amplifier (€200 or more). Its function is:
increase the output power of the car radio,
make that energy available to the speakers.
Good to know : it is important to emphasize that power is not the determining factor for sound quality and that sound reproduction is more important than the influx of decibels that are dangerous for the auditory system.
