I have a new 320d F31 touring, and i could not afford the pro bmw options that include a decent sub. So i have a sub and amp from another car.
I know that i can take a feed off one of the speakers under the seats to provide the bass signal to the amp input, but does anyone know where there is a place to get 'accessory power' from?
Just the low current 12v feed that comes on when you turn on the ignition/accessories?
I know i can get the main 12v high tension from the battery via a direct cable and an inline fuse, but i just need to find out where i can get the 12v on/off feed. I did not want to run a feed all the way from under the dash somewhere right back to the boot where the amp will be located.
Any help would be appreciated :-)
