Switched Live in the boot?

In the process of doing a basic upgrade of the sound system in the Z, I'm not looking for top end just a general improvement, I've already replaced the basic speakers with Aliexpress B&O's which are a big improvement but I've also I've picked up an all in one sub/amp under seat style unit to fit in the boot, I've run the cables for everything but need some help identifying an easy access switched live in the boot.

Thinking that the Bluetooth module should have a switched live I can tap into, anyone have a wiring diagram or know which wire it would be, other options/suggestions welcome but really would prefer not to have to route a cable all the way to the front of the car.

Does the amp have a wake up wire? in which case there's pkenty of unswitched power there?

You could tap into the EKP LPFP power lead which is in the RHS of the boot near the bulkhead..

Yes has the main fused 12v, ground and the "remote/wake up wire"

Its just the remote/wake up that i need to connect to turn it on/off with the ignition to save draining the battery, any idea what colour that lead is?

F70 is the switched LPFP feed to the EKP..its red on pin 1 of the EKP

Nice one, thanks for that
