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 a lower power, the speaker will operate at the same efficiency.

This is the last of the main components of the car audio system. Due to its dimensions, shape (box or tube) and large diameter, the speaker is often installed at the rear (luggage) of the vehicle, where it is responsible for emitting the lowest tones, that is, simply bass. Sometimes this component is powered by a multi-channel main amplifier, but in modern systems – especially complex ones, with particularly high efficiency and power – this speaker is usually equipped with its own amplifier. And again, we must not forget that the power of the amplifier must not exceed that of the subwoofer (otherwise it could be damaged) and that this element represents an additional load on the battery. Returning to the amplifier itself, individually designed for medium and large subwoofers, it is worth noting the strong position of single-channel devices, the so-called monoblocks, which achieve high stability at low impedance. They achieve the highest current efficiency and at the same time “deep” bass.

The typology of subwoofers can be summarised in the three most important categories: small low-power speakers (Ø 20-25 cm and 100-200 W RMS), medium speakers (Ø 30-35 cm and 300-500 W RMS) and large speakers (Ø 38-40 cm and 500 W RMS or more). As for the design, the box with one speaker dominates, although the group of models equipped with two speakers (small and medium models) is clearly growing in the market. It is also worth paying attention to speakers, as services dealing with car audio installations offer a wide range of speakers, including bass-reflex, closed-type, or bandpass.
