Does the 2007 GS450h factory ML head unit have a "remote turn on wire"?

Thanks

 

Do you mean for the amp in the back or are you asking if there is a way to turn on the radio without the car being on or something like that?

i guess I am meaning for the amp in the back? maybe this will make more sense? I want to install the JBL MS-8 but would like the unit to turn on at the same time as the head unit and it just not be on all the time while the head unit is not being used so that the electric current is always on the same stride and calibrated by not being off. Hope that makes more sense my friend?

also do you happen to know the speaker specs for your GS400? like the mounting depth, and sizes? THanks buddy
