I tried installing a jb sound projector on the wall

[Creamer]

I missed the level by 1.5 degrees so now it has a slight tilt.
I dont know if i should
1 take it out and smooth the wall fill the holes and plug it with an extention cord
2 leave it as is
3 have a profetional redo it.

Also for some reason i couldnt dril deep into the cement wall.

whenever drilling into walls I feel like I'm going to hit some electrical cable or pipe.
