Got the Front speakers done now.
Bought a strip of metal from home depot to hang the front speakers off the tv.
I cheated and went to work (machine shop) to shear these to length and drill speaker wire holes, slot out the mounting holes.
Milling holes for speaker wire and slotting mounting holes to allow for adjustment.
Speaker wire holes
The center bracket really needed to be a half inch or so longer. But I'm not going to buy another piece just to fix this as somewhere down the road when I upgrade speakers these won't be usable anyways I'm sure.
The right and left speakers I used an 1½" spacer to bring the speakers back flush with the front of the screen.
And you can see that I used split-loom to hide the speaker cables all the way to the wall.
Next is to get the power cable into the wall and into a surge protector safely. I'm going to be doing a homebrew/diy version of the Powerbridge.
Basically you should Not run the power cable that goes into a tv or computer behind the drywall. Reason being that the cable could get warm and over time without the heat escaping, insulation become brittle, etc etc, house fire, Insurance not cover because of a code violation. etc etc. You get the picture.
So I will post about this when I actually do it.
Meantime you might want to check your Flat panel tv (if you have one) and make sure the power cable isn't getting (pretty) warm. If it is you need to get a thicker gauge cable.
In my case, I need a 16 gauge cable for my 50" plasma because the 18 gauge was heating up. I'm not sure but maybe with 42" you can get away with the 18 gauge wire which is more common, for computers and smaller pc monitors, etc.
I tried a 16 gauge that came with my PC upgraded power supply, and it seems to be fine so. . .
