8 AWG? Bad?

post #1 of 14
Thread Starter 
Hi I have 8 AWG speaker wire, I know probably a over kill but I got it for free so I'm not complaining. My question is I'm wanting to use them on my front JBL L880 speaker in a bi- amp setup with my Yamaha rxv1800. Is this going to be bad for the speakers or amp etc.
specs of cable:
Conductor material: OFC
• Current capacity: 56A
• Total diameter: 6.7mm
• AWG: 8
• Stranding: 7x101x0.12mm x 2
• Insulation material: PVC
• Resistance @ 20ºC: 0.00252ohm/m
• Wire diameter: 4.05mm

Ps: all cable ends have banana plugs on them
Thank you

Having wire that is too high a gauge ( aka too thin) means that it isn't able to pass as much power and for speakers that could mean it would interfere with the sound.

Having lower gauge or thicker gauge wire than is strictly needed shouldn't hurt the performance unless somehow the terminations couldn't handle the thicker wire .

The main reason against thicker wire is price and ease of running the wire versus the amount of power needed to drive the speakers.

If the wire is free and of good quality, as far as I know there really isn't a good reason not to use it over a higher gauge thinner wire unless like I said the terminations needed a smaller gauge to fit or would damage the terminals or just not fit.

No, there's no issues with the 8awg speaker wire, as long as it's designed for audio purposes. If not, there may or may not be issues. The interconnecting cabling of any system, only needs to be adequate,...nothing more. Expensive, overpriced stuff is senseless in my experience.

Also, you needn't bi-amp, or bi-wire the JBLs, no significant performance gains to be had there.

The real gains are had in optimizing your system to the room. Proper speaker set-up, proper seating, adequate room treatment or positioning of room items relative to system. Do you have any acoustic treatment?

Thanks guys
I'm pretty sure is speaker wire tho it doesn't specify it is oxygen free copper with a silvery coating?
Also I have no acoustic treatment in my media room. My equipment is
JBL studio surround sound and paradigm studio sub 12 with Yamaha rxv1800.
I heard BI amping was really worth it? Is this not the case. I have read many threads on here about it and its very divided.

Thank you

This is the cable I'm using

Good speaker wire is quite affordable at Monoprice - why not just get some and stop worrying??

"It was free"
I was thinking thicker is better and less resistance. I know it was a over kill but thought its all good it was free but just making sure it wouldn't affect the system negatively

The other thing is the wire is cooper but has a silvery/coopery look to it? Do you think it may have a coating?

It's probably tinned copper.

BTW, large closely coupled conductors form pretty good capacitors.

Agreed.

The worst thing about 8 gauge wire is that it often won't fit into most terminals and connectors.

Since it is stranded, the solution is to simply cut off stands until the remaining ones, when twisted together, fit into the terminal(s).

An alternative is to splice a foot or less of smaller cable to each end. Solder and shrink wrap and all its well.

Is Tinned copper good?

Yes. It prevents corrosion and is easier to solder to.
It's the same reason steel cans are "tinned".

Assuming the speakers and the receiver can accept banana plugs, there may not be any issues. OTOH if they don't, I'd recommend to not butcher the "free" speaker cables. Sell them on Craigslist or Ebay and use the profit to buy 12 or 14AWG speaker wire.
