Amplifier Kicx Kap 29: description, specifications and reviews
The emergence of amplifiers for a car in the late 70s of the last century can be explained by the proliferation of multiband acoustics systems (speakers) with heads in a closed type housing. Compared with broadband, they have a lower sensitivity. Radio receivers and car receivers at that time had a power of 5 W, and the potential of modern speakers was not fully utilized.
Amplifiers for cars are divided into classes. For people who do not understand all the subtleties of electrical engineering, it is quite easy to explain:
- Class A amplifiers have high sound quality and low power. They are used in expensive systems.
- Class AB is the most common and popular. The sound has average quality. They have optimal power. This equipment has an acceptable cost.
- Class D includes amplifiers whose signal is processed at the digital level.They have high power, but sound quality is low.
The first amplifiers for cars
The first models were called boosters. They represented the bridge version of the UMZCH ordinary.
With a 12-volt supply voltage indicator, the maximum power with a 4-ohm load was 15–20 W per channel. Some designs assumed the presence of volume controls, timbre, equalizers, as well as inputs of a linear type.
At the initial stages of production, the amplifiers were assembled on the basis of discrete elements, later on microchips were used.
Requirements for the sound quality of the car was growing. This forced developers to increase the input power level of the built-in models. Further improvement in the technical data for car amplifiers has increased the supply voltage. Thus, new devices appeared with the presence of a power converter. Competition in the production of tape recorders with a high voltage level continues in the present. In 2000, a model with an output power of 30 watts per channel was invented.
Features of car amplifiers
In terms of their structure, car amplifiers are no different from models designed for the home.However, the scope of application gives them their specific features, which made it possible to isolate products into a separate class of technical devices.
- First, they have a pulse voltage converter. It should be bipolar to eliminate the separation capacitor at the output and have a figure in the range of 50 V. In the highest category amplifiers, each channel is equipped with a separate power supply, which reduces the level of interference.
- Secondly, car amplifiers have a wide regulatory system. The vast majority of models have filters. They are not in simple devices and models intended for professional use (electronic crossovers). The filter function is the separation of the frequency range in multiband systems. In simple models, filters are not subject to adjustment, in complex devices it is possible to change the frequency and nature of the filter. If you do not need filters, you can disable them.
- Thirdly, in many devices besides the linear outputs there are also high-level entrances (High Input). They are intended for use with amplifiers with a head unit that is not equipped with a linear output.High-level inputs in some models perform the control function. In addition, it assumes the presence of differential inputs, which are characterized by low sensitivity to interference.
The structure of car amplifiers
Structural features of all models are very diverse. There are models with one, two, four, five and six channels. Devices with a large number of channels, as a rule, are used in systems with multi-band gain.

General tips when choosing a car amplifier
Choosing the right speaker system for your car is quite a serious matter. Listening to several sound options of different models, as a rule, is an impossible task. Therefore, the acquisition should be based on the company and the level of its experience. You also need to listen to the advice of sellers or installation technicians, to take advantage of other people's feedback.
The most important indicator on which to rely is the power of the model.The basis of the power level of the model Kicx KAP-29 is taken as a nominal figure.
Also pay attention to the rating of the amplifier fuses, sound quality. The optimal power in the system should have a subwoofer. It is also important that an indicator of high quality products is the presence of a certificate with the series number and manual measurement of the power of the device. Kicx Kap 29, the measurement of which is 470 max. and 560 peak, characterized by stability and reliability.
Built-in crossover amplifier Kicx KAP-29 makes it possible to remove from the channel the minimum frequency, as well as the average bass. In addition, there is a bass enhancement at a given frequency.
Usually one amplifier setup is not enough. You need to be able to properly adjust it. The more controllers a system has, the better it is.
The economical use of wires leads to the fact that the amplifier does not reproduce sound at the proper level. Installing and configuring the amplifier Kicx Kap 29 amplifier with your own hands without the participation of a qualified master leads to undesirable results.
For example, in the system claps can be heard when connected, it can produce very poor quality sound.
To obtain the desired power in this model is possible only if it is properly installed when using wires with the desired cross section.
