A sound system engineering commissioning, VAS 5054A is a requires both technology and experience and the need to serious and meticulous spirit work, when the design and construction are meet the requirements, debugging is not reasonable not careful, not only can't show system design effect, but also can make the equipment working in normal condition. So in debugging before fully realize the importance of the work.
Write this article debugging guide because we work in the modification were encountered in the debugging problems, and the professional degree of careful enough lead to debug appear a series of small defects. Although some small problem does not affect the sound system used, but as a professional car audio modification work personnel VAS 5054A for minimum defects also never allow, professional car audio modification is to in the most professional collocation, installation, debugging to play system best effect. So for example to write a debugging guidelines for sound change workers and are interested in DIY if reference.
With Toyota (Toyota) pula (Prado) encounter - Germany bracks (Brax) : http://bbs.pcauto.com.cn/topic.jsp? Tid = 1122554 for example detailed interpretation top equipment debugging and how to reasonable debugging.
Configuration:
Host: alpine CDA -
BMW GT1 9887
Former sound field: Brax Matrix 2 - way system PP
Former sound field amplifiers: Brax X 2000.2
Ultra-low sound: HelixP 12
Subwoofer amplifier: Helix P200
Wire: Ichibahn IKIT02
See configuration for how to debug believe that professional car audio modification workers may have a certain concept. When the system installation ends, our technician is traditionally has been debugged. Debugging to finally say basic to OK. But audition effect always feel that there are some problems. What exactly is the problem? Only by ear is impossible to recognize what specific difference, what specific differences. Because of its difference is very small, so this time we need with special mixing instrument equipment professional debugging, especially as Germany's top brand Brax, Helix these high quality, high standard equipment, Germany Brax, Helix is love in order to meet the high quality music, the high standard requirement and have special music taste of the people from all walks of life. Brax, Helix equipment delicate element all passes through the strict independence detection and precise matching. German products strict process, so in the debugging is need to be very strict and rigorous. A sound system of professional debugging, it must be a sound system for all equipment make a comprehensive understanding, familiar, especially to do debugging equipment, such as power amplifier, main engine. This makes a complete set of system are the most professional debugging.

Look at the sound engineer how to Diagnostics OBD2 teach you refit vehicle sound
Not long ago, in Beijing car city auto parts
Diagnostics OBD2 focusing on "auto aftermarket service quality competition", many consumers car audio modification of put forward many questions. For this, the reporter visited the city auto parts, car audio senior technicians, please they sound refitted some problems do solutions for consumer reference.
Sheet metal is the first interference factors
What kind of car suitable to install what kind of sound, how to achieve the best effect. Generally speaking, the car in the course of driving when plate gold and sound low-frequency replay, if sheet metal partial thin words, can produce resonance a low frequency noise, will have more cover music of the low frequency part, thus affecting the car DVD stereoscopic effect.
Horn position is very Diagnostics OBD2 critical
In addition to the difference of structure of the body, but a different car the car original horn installation Settings habits are also different. If only buy installation common stereo system, the owners were the best car will be placed in the back door of the horn in the car door. And if installation AV system of words, as the pursuit of surround effect can be imitated, system and series car, but in the pillow parts the horn. As for the front door of the car horn, it should be the alto horn installed in front door plank place, Alt installed in instrument desk or A column in the best sound.
Engine noise can also affect effect
In addition to body thickness, the original car horn sound effect for the car the impact of outside, automobile engine working state and work noise characteristics in the car audio effect also have greater interference. Therefore, in the inside vehicle acoustics, must pay attention to in the engine parts the soundproof cotton, with a view to play a sound Diagnostics OBD2 insulation, sound absorption, purify crew enjoy car audio environment.
Electronic system interference can not be ignored
In addition, with modern car height automation, car body of all kinds of circuit system is densely covered, the electronic system in owners bring great rides convenience and fun at the same time, but also to a certain extent interference people enjoy pure car stereo. General Japanese car circuit to acoustic interference will be a little bit small. This is because the Japanese car computer system often use less well than the system and the system more cars's sake, and the system beauty Outil de crochetage automobile cars use commonly vehicle-mounted computer frequency is higher, therefore more prone to interference sound system of electronic noise.

A variety of analytic solution to solve steering wheel
With the growth of the automobile
Renault CAN Clip mileage, vehicles will appear this kind of kinds of problems, many owners will find their own car began to run partial, steering wheel also tilt, steering after self-return the. And some of the more serious phenomenon, such as the car steering wheel jitter, body, also with shaking up. Actually these phenomenon is easy to solve, only need two sets of equipment, the two sets of equipment is very familiar with all the four wheel locator, and the wheel dynamic balancing machine.
The car steering wheel, steering knuckle and front axle between the three installation has certain relative position, this has certain relative position installation is called the steering wheel positioning, which is also called wheel alignment. Wheel alignment including caster, kingpin inclination, wheel camber and wheel toe-in, this is the two steering wheel concerned. The two rear wheel is also being and rear axle installation between the relative position, says rear wheel positioning, rear wheel positioning including wheel camber and one rear wheel toe-in, such wheel alignment and rear wheel positioning to sum up: call four-wheel positioning.
When the vehicle after period of time, chassis components can appear wear away, so the orientation Angle will be in use changes, eventually lead to partial, steering wheel is driving to run these phenomenon. For most for private cars, suggest intervals of one year or traveling 20000 km a positioning, four-wheel positioning can avoid tire abnormal wear, make the vehicle keep linear traffic, reduce the burning consumption and the loss of suspension components.
The car wheel is by the tire and hub consisting of a whole, but as a result of manufacturing reasons, so BMW GT1 that the whole of the parts of the mass distribution may not very uniform. When the wheel high-speed rotating after get up, can form dynamic imbalance state, caused the vehicle in the car wheel jitter, the steering wheel vibration phenomenon. In order to avoid this kind of phenomenon or eliminate the phenomenon, must through the increase weight method, correction wheel each edge part of the balance, the correction of the process is called dynamic balance.
Many careful owners will be found that the wheel hub on the edge of a block or more block size ranging from small lead, and beautiful hub, compared to these lead like some not too phase contrast. But it is a small lead, high-speed stability of automobile plays a very important role. When vehicles in high-speed appeared in the steering wheel jitter, body shaking and accelerator pedal vibration, may be wheel unbalance, right now you need to 4 s shop to wheel to balance into action. Lead MaxiDAS DS708 the parts although small, but its effect is very big, the lack of it will lead to abnormal tire wear, will seriously affect the stability of driving.

Correctly refitted and put on the brakes
1, brake pump flow inadequate:
If only increase each wheel brake launch x431 gx3 cylinder (brake calipers), increase the portion of pump promote brake linings of piston is more and more, need time unit of the supply of brake oil are also more, but our users don't replace brake pump, total pump oil supply is according to the original points pump design, unable to supply new oita pump enough oil.
Such as the original brake pump in all braking condition can be total per second to points pump brake oil is 220 ml, and its matching is original single piston braking points pump, if I reloading the AP big six piston brake points pump per second, need to inject 400 ml brake oil to achieve the maximum braking power, at that time, our total pump obvious "blood" is insufficient, brake points pump nature also unable to fully promote the brake pads to full friction, maybe your side to step on the brake, but points pump because oil supply is insufficient, only realize the 60% of strength.
2, open skin not completely
Because change brake disc size, no grind the brake disc surface, the brake disc surface uneven will lead to the steering wheel braking jitter. The situation in the beginning no break-in is hard to find, and low speed condition, because is not obvious so unable to detect. Actually, does not affect the effect of the brake, but for a long time to brake pad adverse to burnish is necessary.
Brake just installed, in addition to trial, the master can carries on the preliminary break-in. And opcom op com the true completely break-in, still need a period of time, at least hundreds of kilometers, before that had better not have that kind of activation of ABS brakes.
3, error maintenance methods: in the long run high speed or intense driving, brake disc temperature is very high. Some owners discovered car eager to brake disc cooling water to help. Actually this kind of practice is push them, the brake disc is very adverse. Because the metal brake disc in high temperature conditions forced cold and hot exchange can cause metal brittleness increases, the brake disc easily happened deformation or cracking, the serious influence braking effect. To brake on a plate watering is absolutely not worth the cost, it's not science!
Four, about the brake disc of punch or grooving:
Some owners see modified brake disc have punched or grooving, will initiation to their original car ford vcm ids brake to the idea of feet. First of all, we should first understand the brake disc of punch or grooving role. Dish drilling row tank role has three: one is known as the cooling, two can restrain brake noise, three is actually side effect, is that it can reduce weight.

1) can't into record control program, the main reason is the device for tablet and input not connect (both host not with CD box connection), or loading CD box is not put in place.
2) don't play the specified records, and play other record, the reason is:
² designated disc anomalies, should clean record. Don't clean record down the CD trajectory turn the brush, should to the outside, and track vertical brush, so not damage signal path.
² record in the wrong direction (whether to put back the), normal in the can.
² record have greater damage, should be clear.
3) jump tone.
² record automatically Renault CAN Clip change the machine contact foreign body, such as the trunk, bulky items.
² record have damage or contamination dirt, etc., such as parking at the same position after still appear ran sound phenomenon, belong to record problem, must clean record.
4) in machine shows that play but no sound, the microprocessor has not normal operation, press the reset button the operation of the normal.
5) to solve will not play designated tracks method is to remove "random broadcast/change machine play" model.
6) in the event of coil winding fault, please immediately shutdown, and eliminate this offer, you shall never again, in order to avoid damage the bald.
Introduced above is car audio basic maintenance and simple troubleshooting methods, if still cannot be used properly, please contact with my center, oneself do not optional drag down machine, in order to avoid expand fault.
2, tape part (tape protection)
1) don't touch the surface of the magnetic tape, because the dust will pollution head.
2) make tape from containing magnetic materials equipment, such as speaker, amplifier etc to prevent prevent prevent erase or destroy tape on the storage of information.
3) do not use tape exposed to Renault CAN Clip direct sunlight (such as the front windshield) place or in low temperature, the damp environment.
4) relaxation of magnetic tapes, might be haunted tape mechanism. So in the loading before the tape used pencil or similar tool, insert tape rotating shaft of tightening relaxation of the tape.
5) warping tapes or cassete not stick fast label, may in the loading tapes or exclusion cassete caused when the trouble.
6) suggest using tape length below 90 points tape. Because long article tape is very thin, easy to be pulled, cause mechanical failure.
7) tape playback, high attenuation or a track channel acoustic small even silent, this kind of failure for head pollution, clean head can solve.
8) playback tapes throw turn, not on the tail will automatically change the surface, the problem is due to roll too tight, should use normal magnetic tape.
9) tape it doesn't fit or there are tape playback display, but not the sound, this most is due to tape out power on or in the load on the way out to cause, though not in the magnetic tape, operation panel will display tape playback state, this solution is to click on the belt key, first reset and stuck with it.
3, the radio
1) radio signal is very weak, nissan consult 3 even couldn't get a signal. First of all check whether the antenna pull out or extend, joint whether plug firm, antenna whether internal short circuit or open circuit; If the signal is weak, but can listen to, can use manual sorting table or answer required station, or open the remote receiving (DX) mode, then again can be automatic sorting table.
2) if the receiving station less frequency display only dual singular or only when please check system is choosing the right.
3) if the choice of radio stations, ignition switch in "OFF" store content disappear, please check the power cord (BATT line), whether to have electric (should be semester electric)

Car audio modification - installation process decided to uobd2 sound quality
To install as your car stereo is not a simple
uobd2 matter. Experts say: three points equipment seven subpackage, car audio installation is a comprehensive technology and art. Requirements for automobile technician circuit and audio circuit very understanding, can't install sound and influence the performance of the car, also cannot leave unsafe hidden trouble.
Equipment collocation: the style is unified
The collocation of equipment is installed sound the first link. If the equipment collocation is not reasonable, the installation process again good is idle work.
Collocation principle should be from sound system whole consideration: host and the speaker's quality not matching, the host power or power amplifier power and loudspeaker power don't match, obd2 the choice speaker only look at power from sensitivity, are not reasonable collocation, wasting. In addition, in accordance with the owners of the be fond of music style also is very important. Car audio can be roughly divided into two schools: quality type to classical music, symphony is given priority to, Energizer type, in order to pop music, rock music is given priority to. Host, power amplifier, the speaker should be in the same style configuration, with attention bass effect equipment appreciate classical music, hard to avoid then.
Choose wire: pay attention to shield
Wire is to install a sound system of the second link. Wire has direct influence on quality and safety. Wire into signal lines, power lines and loudspeaker line, had better choose high oxidation, high conductivity and outside leather bag is PVC, PE, PP etc material wire.
Signal wire consider shielding. Choose double shield wire, can enhance anti-jamming, to prevent noise into.
The power cord consider conductivity. Car audio special multicore copper wire, not only impedance is small, high conductivity, and wire skins are high temperature resistant, obd2 high flame retardant, anti-aging. Wire diameter superfine wire will fever caused by heat loss and even cause fire.
The speaker line to consider high low temperature, anti-aging. Wire appropriate chooses titanium, silver plating, anaerobic copper material, use different wire, sound quality will be a slight difference.
Gold-plated insurance: to prevent short circuit
Car audio is in the turbulence vibration, temperature is high, the current big bad environment, if the power cord skin be ground open or vehicle collision caused by body short circuit, easy to cause fire. Use gold-plated insurance seat, can prevent short circuit and oxidation corrosion, the elimination of potential hidden trouble.
Wiring craft: coordination is beautiful
In the process of car audio install opcom op com ation must pay attention to the two principles: one is to go line cannot affect the original car line, making bass speaker cannot destroy the body, with the original car equipment to the overall layout and color coordination is beautiful. The second is wiring stay away from the computer and control system, avoid the wiring position is not reasonable, make the car appliances and sound system mutual interference. Acoustic power must choose main line or battery, avoid big current cause fire.
High-end audio systems to vehicles sound-absorbing processing, and production loudspeaker fixed washer; Need stiletto also cannot affect the working conditions of car, prevent fire; Bass speaker speaker unit according to the given data, conduct volume calculation according to the requirements after making housing.
