My car was installing “ always is the cacophony that has ’ of ‘ Zhi Zhi in the acoustics after bass prepares Chinese medicine by roasting it in a pan, how be dropped, I am flat the line that prepares Chinese medicine by roasting it in a pan bass gives cut off. ” car advocate prevent the gentleman tells a reporter, after buying a car, he discovers the acoustics of the car is not very good, to enjoy more pleasant music, he installed artillery piece of a bass in market of automobile articles for use, who knows to return trashy a few days of noise that give out ” of “ Zhi Zhi. After passing careful observation, he just discovers in the car by installation the acoustics in mothball compartment gives out this kind of sound.
■ CD lead plane takes report to affect acoustics life
Subsequently, he drives the car professional car acoustics inn to undertake checking, maintenance master worker found the solution very quickly, the reason is receive power supply cord directly when installation bass prepares Chinese medicine by roasting it in a pan was in at the back of car CD lead plane. Then, the accumulator of instead of power supply cord that maintenance master worker prepares Chinese medicine by roasting it in a pan bass takes report independently and add the ignition after holding control line to try listen, murmur was eliminated.
Old master tells limited company of service of car of Shaanxi luck Lai the reporter, like acoustics this is planted the car electrical appliance of high-power, should take report from car accumulator alone. Prevent the gentleman's acoustics gives out murmur, because when bass prepares Chinese medicine by roasting it in a pan, installation mixes frequency line,be at the same time join was in power supply cord cause at the back of car CD lead plane. Want a car only so one electrify, acoustics can be in electrify open condition, in car voltage flabby circumstance falls, can electric current disturbs frequency to produce voltaic sound in acoustics thereby. Although method of this kind of installation is simple but very insecure, because receive bass to prepare Chinese medicine by roasting it in a pan power supply cord is the power supply cord that should cut open lead plane, if close finally,bad word causes electrical wiring short circuit very easily, and this kind of method will make acoustics long be in open position, shortened the service life of acoustics. So, installation car acoustics (include DVD to wait) when the circuit that had better not touch primary vehicle, take report alone from accumulator however, and should add outfit control line.
■ illicit change circuit to endanger safety and value
Outside the problem that besides the equipment such as acoustics, DVD, navigator need notes to receive report, include car guard against theft implement also put in the issue that receives report likewise. New car in one's hand hind, a lot of cars advocate stem from pair of love cars to be given to love a car to add outfit guard against theft by the afraid meeting of pilfer implement, and present guard against theft implement it is commonly when the car advocate get off system of the guard against theft after locking up the door enters state of alert, once inductor induction suffers collision, door to the car by prize, step on brake, ignition when the illegal operation of these 4 level, lead plane of guard against theft gives out a command to undertake cutting off to the oil path of car, circuit.
