Weak current College】 【car audio FAQ.

1: car audio speakers, suddenly developed fuzzy sound quality?

A: look at the speaker appearance have cracked, if no problem that may host or amplifier (if active) question

2: car audio how links to computer?

For; a computer power supply with wires and also get some of the power amplifier and REM shorted together with root short-term can then put the line received the power of the yellow line. Yellow line is 12V 5V red line is also received from the black line, to the power amplifier on a negative level can

3 ask; on car audio adapted for those that need attention?

Answer: a set of sound now the most common combination is: audio sources + amplifier + speaker (speaker)

Their influence on the sound sources for: < < speaker amplifier. If you want to change, it's a good idea to first change the Horn speakers and a car amplifier with heat exchanger, the sound quality plays a decisive role. The sound on your head and say, if you have a drive can not change, if you are on tape, and it is definitely going to change it, first of all, converted audio is considered before the sound field, former sound field also is important, as is the best location for you to listen to, standard, you sit in the front should be can't hear that sound behind. This is the game-level audio will sound field in order to highlight the former, but gave up after the acoustic speaker is performance, while the host is the audio sources, there is no good sources are not. It is recommended that the landlord is according to their own needs to modified sound. Initially we are converted, it is recommended that you replace both before and after the Horn, together with the host, this way, the effect will be greater than the original car with leap.

4: car audio conversion on the car?

A: the converted audio will not affect the dynamic performance of vehicles, but battery life is affected, with rectifier and wires, etc, more secure! it and air conditioning, air conditioning compressor need to drive, so the engine will take part of the engine's power!

5: car audio equipment with the most attention?

A.; sound is very personalized, there is taste, not like some kind of style, "turnip cabbage, something to love". Some people like electronics, enthusiastic dahao style, some people love thin, pale recluse qingyi off, someone like scene character epic orchestral percussion music, rock, heavy metal, someone is willing to mailings to the flowing of pastoral classical music, you elegant, reminding about the solo music, as well as sweet, thick voice playback ... Audio must be selected to suit your own style, so not sure jeepers hobby before, I am afraid I cannot give you any advice.

6 q: car audio conversion problems with ground noise

1. protection of the Earth is to prevent the power polarity reversed causing damage to the equipment of the protective device, the simple way is the power supply input to ground plus reverse diode, car audio equipment is particularly common in the circuit.

2. shield is to prevent electromagnetic induction and Visual and audio cable shielded metal jacketing, electronic equipment, metal shell, shielding enclosures, buildings of metal shielding NET

3. over-voltage protection earthing
This is set to high voltage power and grounding protection device. -Point the spark for the most widely used is the pressure-sensitive diodes and is a bubble. Adopted-grounding absorption and limiting. If the tuner is damaged many high voltage cuanru and striking receiver.

4 car audio special grounding

Number of vehicles installed power amplifier, play loud bass (no more than normal electricity consumption), instrument lights flashing with music, this is because only the amplifier of cathode ray bold and ignore the negative electrode cables, circuits

Formation from the negative to a positive return, then rough anode thin is unable to increase the current, as water-weight does not have water flow flow only in fine. So you want to increase the negative electrode of current, specific practices: 1, engine to batteries a (engine and body is insulation). 2, engine-to-body a (to increase generating capacity). Line thickness is at least as to the positive electrode cable.

5. signal to all kinds of electronic circuit, there is a benchmark potential points of this benchmark potential point, is the signal. Its role is to ensure that the circuit has a unified benchmark potential, not floating, signal errors.
