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.
