Should I ground outdoor speaker wire? If so, how?

No You should ground the amplifier itself, although in most cases this is automatic as part of the power cable and safe domestic wiring. You should not ground the speaker cables though. The amp may ...

Identifying positive and negative speaker wires

Note that the wire doesn't care which is positive and which is negative. Nor do the speakers, really; what matters is that both/all speakers be in phase with each other. So if the same side of the ...

How will I extend my speaker wire?

You can twist together a string of coat hangers and I'd bet you wouldn't notice the sound quality difference. After 5 tests, none could determine which was the Monster 1000 cable or the coat ...

Should I ground outdoor speaker wire? If so, how?

I am not familiar with static or lightning protection concerns and will have to defer to others. However, I would not ground the actual wires running between the amp and the speakers. Some amplifiers ...

Speaker Wires Through Wall

Assuming those speakers are passive (that is, don't have a mains plug and the amplifier built in), then you're going to have a relatively long cable run. It's worth using thicker than normal cable for ...

Running cables for a home theater: inside walls and ceilings or on the surface?

Identifying positive and negative speaker wires

Look closer at the insulation - there's nearly always a physical clue, such as tiny ridges on one wire, not on the other.

Can a multi-meter be used to test home theater receiver speaker output?

Yes, flip the meter to "AC". You should detect a fluctuating AC voltage when sound plays. Some amplifiers also put a DC bias on speaker circuits, you can check for that too by flipping the meter to "...

Do I need special tools to run speaker wire vertically from about light switch heigh to the floor? No fireblocks.

There's probably no reason that it won't work. Just feed the wire in and let gravity do its thing. Use a thin wire to capture the cable at the bottom hole. A wire puller is nothing more than a stiff ...

Could I use this Speaker Wire for my thermostat?

Typical "thermostat wire" is a NEC/UL type CL2 cable, just like your speaker wire says it is, so as a replacement for an 18/2 thermostat cable, this will work just fine.
