Optimum power automotive acoustics

Only an optimal combination of all parameters of sound system (head unit (car radio), speakers, amplifiers and a subwoofer) can provide a stable and pure sound in the cabin of the private vehicle or rental of a car. Determine the required capacity of all components can be examined data that manufacturers usually specify in the instructions. As a rule, the documents identified three parameter power: nominal (RMS), maximum and peak. Under the rated capacity refers to the extent to which speakers work without distortion and noise. At a maximum - perhaps uncritical experience interference, the peak power often leads to mechanical failure of devices. In some cases, the instructions specify only the peak or maximum power, so when buying is to find out all the technical parameters of the sales assistant. If you, for example, are interested in car rental in St. Petersburg or in Moscow for their honeymoon, you can be sure that the companies providing similar services, installed in the machines only powerful devices that can withstand any load. For personal auto experts recommend choosing amplifiers with a rated capacity of 1.6 times the power of the speakers. This is due to the fact that the sound quality is formed when using amplifiers and speakers 60% to 90% of their rated capacity. With a low power amplifier is sometimes the effect of "clipping", which disables the speakers. Head unit (radio) may cause irreparable harm to the speakers with a very low resistance (2 or 3 ohms), as an amplifier, such loads are extremely critical. When choosing speakers, it should be three basic parameters: power, sensitivity and frequency range. Depends on the power of the maximum volume. But sometimes it is to acquire less powerful and more sensitive dynamics: the power and sound quality, this does not lose, and you will win in the cost of acoustics. Power amplifier has bass in 2-4 times the power of broadband speakers. So you get the optimum volume of the subwoofer. From the perspective of professionals, the best option - it is a model with 2-4-autonomous winding voice coil - more powerful than similar devices. If you select all the components of the acoustic system of the car, consider the possibility of its on-board power supply.
