Computer and electronic device of car not to disturb the sound of a line, otherwise there will be trouble. The installation must have the professional training of personnel, to ensure the safety of. 2, the dismantling of the technical process of modification: sound, first of all to remove the original car audio, whether is the fundamental problem of disassembly modified, because now the instrument surface is not to screw, so need to pry the decoration parts to see screws, remove the operation requires professional and strict, otherwise easy to remove bad. The second step, the wiring is required, replacing the speaker, to door, door, disassembly dashboard, seats, and other decorative plate, in the process of disassembly to have special tools, to maintain the original intact, otherwise it will not pretty and not sealed noise. 3, whether the product is qualified: now there are many counterfeit brand-name equipment on the market, at the time of purchase must distinguish, otherwise no end of trouble for the future. Some of the low price of the equipment, from the appearance is not quality problem, however, the internal components are poor, circuit in the design also does not conform to the standard, the equipment quality is not that bad, is prone to failure, and even generate natural. Must be to the manufacturers authorized stores to buy, can rest assured that the use of. 4, the sound effect how?

The above is the professional and non professional technical difference, this is also the difference between professional and non professional price level, the final is a concept of value, is the choice of price or value choice. Don't install sound as a very easy thing, not connect line sound rang for it, not only the sound quality can not be guaranteed, and the adverse factors and hidden in them, so the emphasis to professional shop to install, can guarantee.
