Mistakes in the eobd2 modified car stereo

Misunderstanding:

    Price for a friend buy car audio  eobd2  there are two extreme measure, excessive pursuit of high-priced products that election more expensive the better; another against the Daoxing, the cheaper the more cardiac fact, these two The ideas are not desirable. The brief analysis is as follows:
Exclude shoddy deceive means expensive audio quality is really good, but whether your actual modifications need, they need to be scrutinized. There are several criteria: First, the full set of sound required power whether additional car engine rated power range; whether your model is suitable for installation multichannel speaker; your ears withstand professional equipment sound pressure. No one will be willing to pay big bucks to buy their own sins.
2, some friends think The audio conversion nothing more than another head or speakers, selected substitute the cheaper the better. In fact, for the sellers, and the cheaper stuff profit but the higher, they badly defective quickly shot, not to mention can not guarantee that this deformity with modification effect, a bargain only rough wire, circuit design for high temperature, electromagnetic interference great risks and so left, ranging from burning machine, while threatening the electronic circuit of the original car and vehicle safety.
Myth: too much emphasis on the bass

    Large diameter subwoofer (not less than 8-inch cone) and drive amplifier bass external power, does not know that it will become noise distortion state bass. Woofer placement is also very important, if your trunk is large enough, the subwoofer amplifier Ann here, less noise due to engines, doors, seats, etc., more pure bass at this time, plump. Otherwise, no matter how stressed bass deceive ourselves.
Myth: the pursuit of the idea one step unrealistic

    A beginning of a novice user,  uobd2   via a simple modification to clear their own tastes, such consideration of low effect; "big point of surgery." Next, it is necessary to move according to their own preferences, such as all kinds of number of speakers or amplifier installation position, and the desired effects obtained. Before the age of 30, you may like the the metal strong sense of rock, is sensitive to the treble, bass. With age, your state of mind will become increasingly calm and listen to the most is Listening or symphony, the step modification premise is neither scientific nor humane, we can not be done once and for all.
Myth: equal to the car stereo home audio

    The car stereo Unlike home audio, often sets sales, buy a home wired you can use. Moreover, the entire car audio power required and the modified car engine performance, host and speaker, speaker with amplifier and so there is a performance matching problem can not be vague. The reason is simple, the interior space is much smaller than the room, the sound waves susceptible to electromagnetic noise interference, the sound field will also vary with the speakers, amplifiers and other installation   lexia 3  parts effect. In short, we can not be blind to believe that the effect audition cabinet.
