Hi, I am very curious I have everything plugged in and ready to go for my subwoofers. It’s all put in through the door speakers. My only problem is I can not get a signal for my amplifier for the subs to turn on. Is there any signal wires that turn on and stay on while the car is running? If so, please please please let me know ASAP on where, how to get to it, and anything u believe you I would need to know to get the signal to turn the amplifier on!
