However, the average car music lover mainly associates the amplifier with the ability to get powerful bass and boost the mids. When choosing an amplifier, it is important not only the quality, but also the number of supported channels, as this is reflected in the number of receivers that can be connected to it. The most popular for years are the 4-channel amplifiers , which allow the connection of 2 speaker sections, a radio and a small or medium-sized subwoofer, the latter being increasingly served by its own power supply system. Another important attribute of the main amplifier is its power, which cannot be chosen randomly. This power must be compatible with the power of the device’s speakers, based on the principle “power of the source = 1/2 to 2/3 of the power of the connected speakers”, which arises from the need to protect the speakers from damage caused by a power supply that is too powerful. Therefore, when deciding to replace the speakers and amplifier, you must first calculate these two quantities and adjust the amplifier (its power) to the desired power of the speaker.
It is this part of the car’s original equipment that is part of its main console and affects the aesthetics of the entire interior. Therefore, the decision to replace it is often associated with the need to convert the console, although it often implies the acquisition of a higher quality model with identical dimensions that guarantees a smooth installation in the existing niche. The function of the radio is as follows: it plays sounds from different carriers or through wireless communication modules (CD / CD-R / DVD / pendrive / Bluetooth / Wi-Fi / radio waves received by external antenna).
