Hi There,
I am currently renovating my lounge and need to cut an inwall speaker into the inner leaf of my exterior wall.
The house was built in the mid 70s and has a concrete block inner leaf.
The speaker gets mounted into a box that is secured into the wall. The hole I need to cut is 435mm wide by 590mm high and needs to go all the way though the inner leaf as the box is 120mm deep.

Are there any building regs for doing this sort of thing? And do you think the wall will need support for such a big hole?
I've read that for chases, you are only allowed to go 1/3 the depth of the wall deep, would this rule apply to what I am doing?
This is my first home and have recently moved in so I am very new to the DIY scene so apologies if this is a stupid question.
Any guidance would be greatly appreciated!
