14awg should be fine. Just make sure you get cl2 or cl3 or better rated wire if you want to run it in wall.

actually for 12 ft you only really need 18 gauge so even 16 or 14 is fine.

14 gauge is plenty for that length of run.

what does American Gauge means?
I need full quality audio coming from that HD DVD player, which maximize the definition of HD audio~

I see a 4 meter run. I figure nobody wants cable all over the floor to trip over, so this will be a in wall run. 3 meters up 4 meters across and 3 meters down. Now thats over 30 feet, if it is an in wall run, as I figure, does anybody out there still want to do 14ga? Not me, i'll go 12ga. Even if it is all over the floor, whats the cost difference between 14 and 12ga.

Nobody has asked the two most important questions:

> What impedance are the speakers?
> What is the power level you'll be running?

the cost is so little why not run the 12awg as mauney pointed out those varibles are
to be considered so later if you upgrade to lower impedance speakers with a high
current amp your set if you don't then it won't hurt anything anyway.he said room
was big it would have helped if he said how many feet to rears from eq.

Why are those important questions?

The only real reason you need thicker gauge speaker cables is because of the current demand the speaker will put on the amp..

i.e. speaker impedance (speaker) and power level (amp) are just as important if not more than distance which contributes to impedance..

American Wire Gauge (e.g. 14 AWG) refers to how many turns per inch the bare wire covers. So for that example, 14 turns in one inch means the wire is 1/14" diameter, without insulation. 10 gauge wire would be 1/10" (0.10 in) and so on. So the LOWER the gauge number, the thicker the wire. Here, 10 gauge is noticeably thicker than 14 gauge.

Similar scales are used for lots of different hardware. Shotgun gauges are totally different.

Check this link out. Good reading on speaker wire:

http://www.roger-russell.com/wire/wire.htm#introduction

I think 14 AWG would be sufficient for you.

Mostly true, but you left something out. You also need thicker gauge because of the signal loss in longer runs. His distance isn't too long, so he doesn't need 10 or 12 gauge even if he has an impedance of 4 ohms. 14 gauge wire with a 4 ohm impedance can be run about 40 feet without signal loss; should be all he needs unless his rears and back speaker are more than 40 feet from the preamp/receiver.

Here's a chart to go by:

Is using a wire with a higher gauge than necessary, a problem? Say if my rear speakers need 12AWG and I use the same AWG wire for my front as well. Will it affect my front audio?

No. Using larger wire than necessary will never hurt anything - it just may cost more.

That said, if you're wiring a complete 7.1 system in-wall, I personally find it easier to just get a spool of the biggest stuff you'll need and run the same thing for everything.

14 is plenty. 12 is just silly. seriously. I use 12awg for subs in my car. Complete overkill in HT. 4 meters is not that far. If it makes you guys feel better to run 12awg, go for it though, nothing wrong with piece of mind!

In the end, buy whatever gauge makes you feel secure. If you want 12 or 10 - cool. You just don't need it for that length.

What if I am wiring my basement for a home theatre and plan on using Definitive tech speakers but already wired with 14awg and the longest run is 35ft. Need help with this fast cause the drywallers are coming this week.

+2 also when the cable is finally installed you will find that most
of the time it will eat up more footage on final install do to the
wall and ceiling construction did you compensate for the ability
to leave slack for removal or repair and if you change equipment.

No I cant see being able to reroute new wires once it is drywalled due to complexity of the design of the ac ducting and the water and electrical service. Also i routed the wire in such a way as to not touch any existing electrical wires. Will the 14 be enough? Like i said they are 8ohm speakers which will be definitive technology 7002s and CLR 3000 center channel. They will suck a lot of juice but like i said the 14awg is already ran now. What to do guys? chime in please!

14ga will be fine...but since it's clearly eating at you, might just as well replace it with what will make you happy and clear your conscience.

Just because there is a knob doesn't mean you should turn it.

Well on monoprice right now the 12awg is only $2 more, I would (and did) get that, there is no reason not to get the bigger gauge, and it will have a tiny bit less resistance with a bigger wire at any length, it just might not be noticeable at very short lengths.

Except if you want to hide the wires or they don't fit well in your terminals.

Ok, just got back from homedepot, lowes, ultimate electronics. No 12awg 2 conductor in wall available, rediculous! My drywaller will be here by thursday and my order will not make it here untill at least wednesday, (gamble). I wont pay for next day air cuz its over 100 dollars, lol. I am going to go with the 14awg I already have routed I guess even though it is eatin me up. I just listened to the BP7002`s again at ultimate and lol, they have them hooked up to 16awg wire but are only about a 10 ft run, sounded awesome. Its still eatin at me, damn. I measured my longest wire run at 37ft for the left surround speaker and the furthest front is a 21 ft. With those numbers am i good to go with this setup and the 14awg? sorry to drag this on!

When a man asks a question like should I get this for more money or that for less money, there is an internal conscious/subconcious struggle going on that's based on what you know and what you're just not sure of. In a situation like this, which is the equivalent of getting a half-way decent lap dance with no tipping, I say get the thicker wire and if you've got extra money, treat yourself to a lap dance.

I'm in a similar situation. I will be implementing a 4 speaker, 1 sub, 1 center speaker system. I live in an apartment.

The center, sub, and two front speakers will be less than 5 feet away from my amp. The two rear speakers will be 10-15 feet away from the sub. I recently purchased 16AWG wire. Should I switch to 14AWG wire or stay with the 16? I reviewed the chart online, however I'm confused about OHM.

Lastly, at this short of a difference, will there be any noticeable sound difference between 14AWG and 16AWG?
