FAQ

Q : Why the volume is not loud enough even I set the volume to 100?
A:The sound decrease button may be activated when you install the APP in the first time, press the sound decrease button 1~3 times to have a louder sound;

Q : Why the sound is strange (absence of low frequency feeling) when two loudspeakers connected? And when only one loudspeaker is used, why it sounds better?
A : The sound has not only amplitude but also PHASE information. If the two loudspeakers are anti-phase, the lowfrequency sounds emitted by the two loudspeakers will cancel each other, which works similar as the active
sound cancelling headphone.
You just need change the two terminals position of one of the loudspeaker to make the two loudspeakers have the same PHASE. As show in the following figure, wire position of “RED (up) Black (Down)” has been changed to”RED (down) Black (up)”
If you think two loudspeakers still cannot meet your requirement, we can extend to 3,4,5…loudspeakers as youwish. But first you should check whether you have enough space to install more loudspeakers.

Q : Why I cannot download the CAN data successfully?
A : Please make sure your phone internet connection is 0K first.
APPLE phone can almost 100% successfully download by pressing the “DOWNLOAD” button one time.
For Android phones, due to the Bluetooth connection is more complex, you may need try a few more times until
the dialog box “Download succeed” appears.

Q : Why I change the number of “RPM transfer”, I can not hear the sound changes?
A : The effect of “RPM transfer” can be observed when you drive the car. If your car is not moving, it’s hard to tell the difference, since the purpose of “RPM transfer” is to have high engine speed sound at physically low engine speed of the real car.
