I guess you have a built-in amp and subwoofer in your car? You need to send signal to the amp to turn on. It's pin 21 on the picture below - it needs to get +12V to turn the amp on.

The proper way to get +12V signal is to connect it to pin 1 in B connector (AMP-CONT), it outputs +12V only when the head unit is turned on.


Alternatively, if your head unit doesn't have REMOTE output, you can connect it to accessory +12V (pin 2 in the main connector).
