-- Dear customer, the unit has been tested before shipment. If there is no sound, it is
usually a wiring error or the original car speaker wire is short-circuited with iron.
According to the steps to check it.
1.Check if the speaker cable is short-circuited and connected right. Please reconnect if
it have any short circuit.
2.Check how many speaker cables does the original speaker have. If there are only
2 speaker cables then it means that the original car line does not match our unit. In this
case you need to re-organize the original car line. One speaker must lead to 2 speaker
wires; 2 speakers must be have 4 speaker cables, only in this way, the unit can work
properly.
