PUMPKIN CAR STEREO SUPPORT CENTER

Is there any way to get an updated EQ/AMP app to have the subwoofer Supports audio output, and to control it separately.

I have tried to connect my amp/subwoofer to the Front out (red(RIGHT)/white(LEFT)) as well I tried the Back out(red(RIGHT)/white(LEFT)) and Sub out using a Y jack no avail. I get absolutely no sound to the sub from all 3 outputs.
I am not able to get any output from my sub. I believe the sub level is turned off on the unit and I need to find away to turn it on.
I tested my amp and sub in another car the setup worked flawlessly on a pioneer desk.
PS: Other Head units appears to have this functionality not sure why mine does not. Please see attached picture for what I am looking for.
Please advise.

@jammy, I am not seeing your response....

Hi,
sorry for the late reply.
You need to connect the ANT wire or AMP wire to the remote wire/connector of your amp. Then connect the SUB RCA cable to your audio input connectors of the subwoofer via using a Y jack.In addition,Please notice ,only when the frequency of original signal contains 20Hz - 100Hz part,do the SUB output signal .
The subwoofer adjustment function only works in the android 7.1 unit .
