There is an amp mounted to the inside of the cone on the sub and the two front door speakers and another amp behind the driver taillight to run all the other speakers.

I'm not at home so cannot get to my alldatadiy account to look at the details but I'd bet there is a pre-amp signal at the trunk wall amp for the sub.

Good morning everyone, I can not turn on the amplifier, there will be something else that turns it on, connected the positive voltage and ground, I do not know if it's anything to do with the pin (GMLAN data of low speed), please helpme
