I want to connect a car amplifier to skoda karoq Can someone direct me where is the hole in the wall of fire to move the cable to the battery from the passenger compartment please ????

Wall of fire! 

 

 

 

Why would you want to take the feed directly off the battery? when you can access the internal fuse box on the passengers side and utilize one of the unused positions or use a fuse adaptor from one of the many ignition switched sources available..
