First, car audio sound insulation project
To install a good sound effect, sound insulation engineering is an indispensable part. There are many soundproofing materials, such as damping plates, sound-absorbing cotton, wave cotton, noise killers, puffing agents, etc. To do sound insulation, we must do it mainly with sound, especially the horn on the door panel. The back and side of the iron sheet are affixed with a damping plate and sound absorbing cotton.
Second, car audio wire
1, select the wire selection (!) signal line
The smaller the resistance of the signal line, the less power it consumes and the higher the system's effect.
(2) The speaker cable with less resistance is selected, and the smaller the damping coefficient, the smaller the residual vibration of the speaker.
(3) The power line with the larger cross-sectional area is selected. The smaller the resistance value is, the larger the value of the trapped current is, and the larger the output power is.
(4) The insurance value of the insurance seat can be calculated according to the following formula:
Insurance value = sum of total power of the system * 2 average value of the vehicle power supply.
The closer the fuse is to the car battery, the better the power cord between the fuse holder and the battery connector is usually less than 18 inches.
(5) Manufacturing materials for wires All wires are preferably made of non-oxidized, non-magnetic metal materials.
2, wire protection (1) All wires are best to use tin foil as a barrier to avoid current interference.
(2) All wires are preferably protected with bellows to avoid wear and short circuit.
(3) It is better to use a rubber hose as a bridge for the wire passage to avoid short-circuiting due to long-term wear.
(4) All wire terminals must be welded with solder and then heat-shrinked.
3, wiring details
(1) The signal line should be separated from the driving computer, the vehicle relay, the oil pump and the power cord of the power amplifier.
(2) The power cable should be away from the generator and ignition device to prevent noise from radiating into the power cable.
(3) The wiring of the speaker cable and the set of the machine box cable should also leave the power cable of the driving computer, the vehicle relay, the oil pump and the power amplifier.
(4) Remove the paint or rust from the grounding point of the grounding wire, and then firmly fix the grounding wire.
(5) All wires must leave each other, and the distance should be better than 20CM.
Third, car audio equipment installation
1. All equipment should be installed firmly to avoid loose vibration and long time.
2. The rear power fuse box should be away from the audio signal line.
3. The power cord of the fuse box to the power amplifier should be the same length, so as to avoid the potential difference between the power amplifier and generate AC noise.
4, the installation position of the amplifier should consider the heat dissipation problem.
5, all speakers must be shielded, especially the woofer.
6. All power supply positive terminals must be protected.
7. All terminals must be connected with special connectors and soldered with solder.
