Then i've disconected them and connected the oryginal stereo woofers and all worked fine.
Tommorow i'll be installing and alpine retrofit and wondering the wifi woofers will playing good...
The OEM Stereo woofers have jumpers at their OEM connector. There are no jumpers in any other OEM woofer connector.

The jumpers connect pin 1 to pin 2, and pin 3 to pin 4 in the OEM connector.
