I am trying to install a set of 5.1 speakers in my family room.
The family room is like an extension to the house with vaulted ceilings.
Hence both the front and the rear speakers are on external walls.
I have first tried to install the rear speakers, where I am stuck.
The intention is to fish the wires through the rear family-room wall down to the basement and then traverse the breadth of the family room through the basement and then up through the opposite wall of the family room where the receiver is.
I made the necessary hole at the speaker position near the top of the rear wall.
I also made a hole at the bottom of the wall (directly below the first hole) just above the molding through where I intend to make the hole to the bottom plate of the wall (to pass the wires to the basement).
I was able to fish the wire from the top hole to the bottom hole (luckily there were no fire blocks).
But it is here that I am stuck.
I tried to make a hole in the bottom plate of this wall but to no avail.
As per suggestions in another how-to, I am using a 3/4" auger bit.
But the problem is that I have already drilled about 4" but I am still drilling.
I was expecting a 2x4 as the bottom plate and hence having to drill only about 2".
Is it possible that since this is an external wall, what I am drilling into is an end-joist?
I have stopped my drilling because I am afraid of making any structural damage to my house.
Also if it is an end joist, what are my other options in order to successfully complete my project?
BTW, my basement is finished, making it harder for me to determine the exact position where I am drilling.
Any help will be greatly appreciated.
Please let me know if you need any more details/clarifications.
