SNAP: car audio three to elm 327 four principles

Sound beautiful music can always elm 327  bring a happy mood, however, how to modify your car audio, so you can have this agreeable mood? Here, the SNAP vehicle maintenance beauty chain organizations. Dr. Matilda as you made car audio three, four key principles, so that you in on his car was refitted to reference.
SNAP car audio three to listen to the sound field standard, coordination and influence to talk about. First of all, listen to the sound field standard defined in car audio debugging good situation, listen to the sound field in front of the body, sit inside the car to listen to music, like sitting in a concert hall to listen to music, in general, tweeter mounted in front of the body, the bass horn is mounted on the car after car, so installation, listening to the sound field is compared to a standard; secondly, because the body of left, right horn and the ear in different distances, easily lead to the left, the right ear sound coordination, therefore, in your car audio modification, through retrofit  elm 327 technology become a coordinated; again, high-quality audio voice shunt well, the level of clarity, a sense of space, even if the music to the loudest, does not affect the personnel inside the vehicle.
As for how to choose car audio equipment, how to refit a car stereo, should abide by the following four principles:
First, performance, price equilibrium principle
This principle refers to the car audio system with auto grade value of itself in harmony, that is to say, you are in their car audio modification, to conform to the actual situation, namely the car audio system with automotive quality consistent quality, at the same time, also want to consider the cost of your car stereo, in general next, car audio modification cost control in car 5%-20% is more appropriate, in addition, you buy  elm 327 such as host, amplifier, speakers and other audio equipment are semi-finished products, to achieve perfect acoustics, the key is the equipment for a perfect match, therefore, audio conversion technology is very important, there is a point worth note, you buy the audio equipment should be in the same grade, because of different grades of audio equipment performance uneven, if you put them together, may make your car audio effect change in a complete mess.
In second, large power output principle
This principle refers to a set of audio system, host or amplifier continuous output power than the object (i.e., horn ) continuous output power, host or amplifier continuous output power explain its control audio line range, strong ability of driving the speaker. Small power amplifier is easy to cause the distortion of sound, even burning of the power amplifier or speaker coil, but a large power output is also limited, otherwise, too much power assembly causes the waste of electrical energy.
Third, sound natural reproduction BMW GT1  principle
Quality natural reproduction refers to broadcast music and soundtrack music changed little, evaluation of quality indexes of the frequency response curve is smooth, it refers to each range of loud, if each vocal range are consistent, that frequency response curve of smooth and good, then, the sound sense of listening is also very good, in addition, from human subjective consciousness evaluation quality is good or bad, there are three aspects, namely the sound field effect is good, the overall sense of balance and strong sense of hierarchy.

Adapted to BMW 320Li audio small upgrade

You do not know the BMW 3 Series car driving time is not found, in high speed running vehicles will produce larger wind noise, and there are a lot of running noise from the body of the bottom came, very difficult to keep the space inside the car is comfortable, quiet, if this is to listen to some music to ease the mood of driving also, it is difficult to obtain a good listening environment, this is the luxury car. Now ( say many original car are)? Of course not, it's just the car factory in order to save costs.
Since so, through redo the whole vehicle noise can improve this phenomenon? The answer is yes, then many people will say " seen others do the whole vehicle noise, seems to be very complex, and the things in the car are removed, although can put it back together again, but the heart is not practical. " In fact, part of the automobile which one is not removed, the most important thing is whether the assembly in accordance with the standard of conduct, if not in accordance with the norms, even installed a four hole rim will be problems. So, if related to the assembly and disassembly of parts, or professional stores do better, however, if you believe in your ability, can DIY of course.
But for the sound of the professional field, DIY is seemingly impossible task, because the sound is a very subtle thing, it is invisible, like a piece of metal, I think it will be a hole, can play a hole, to get any shapes can be processed, but the sound is not the same, if I'm good bass voice a little, a little sweet, in addition to adjust the EQ equalizer would have its law, not to mention the whole vehicle noise and audio conversion this " project", this seemingly simple installation, which contains very much professional knowledge, in the where as insulation materials should be laying, the materials used to be many; the horn installation angle and so on, every subtle change, will make the sound changes, this is the sound of beauty. This matter should not be delayed. We will have a look, the BMW 320Li two door noise and small horn process.

Figure: before construction, masters to door protection, because to do sound insulation door construction, to the door trim panel and remove, and will use tools, although professional tools are reasonably designed, normal operation is not on the construction site caused the damage, however, in order to avoid inadvertently the human error, is covered with a layer of protection " coat " is very necessary.
