The required mounting depth is also important

Sometimes the magnets are too large and do not fit into the openings prepared for the previous speakers), as well as the place where they will be mounted. Experts strongly advise against mounting them on a rear shelf or anywhere behind the front seats, as this interferes with the good reception of the music – after all, when we go to a concert or use the Hi-Fi system at home, we are usually in front of the sound source because, for our hearing and the shape of our headphones,  That’s the best way to listen. The ideal location for tweeters is near the front console, while woofers should be mounted on the well-insulated ports, and powerful bass speakers can be installed – largely due to their size – at the rear of the car. When installing new speakers on sheet metal, it is worth using MDF spacers (which are more expensive but much more effective than their plastic counterparts) so that the transmission of vibrations to the sheet metal is effectively eliminated.

An absolutely important parameter to consider when selecting new loudspeakers is – in addition to the high quality guaranteed by a reputable manufacturer – the efficiency of the converter, expressed in the unit dB/1 per W/1. This parameter tells us about the volume (sound pressure) generated by the speaker at a distance of 1 meter from it when it is powered by 1W. Because sound pressure is measured on a logarithmic scale, each 1 dB increase in the parameter means an increase in converter volume of approximately 35% (with the same power supply). The speaker’s power rating is also of great importance, as it says less about the maximum volume of the converter and more about the maximum amount of electricity the speaker can safely absorb. This means that when powered by less power, the speaker will operate just as efficiently.
