Canare 4S11G vs 4S8G

[gabrielb]

I decided it is time to replace my old speakers cable and I was looking at Benchmark's NL2->Banana (https://benchmarkmedia.com/collections/cables/products/benchmark-speaker-cable-nl2-to-banana-2-pole).
The problem is that the cable they use (4s11G) is too thick to pass through the existing tunnels (the cables go under the floor).
I saw that canare has a similar lower gauge cable 4s8G (4x16AWG) which should fit the existing tunnels.
The distance is 5-6 meters on the left and 2.5-3 to the right.

Should there be meaningful difference between the 4s11G (4x14AWG) and the 4s8G (4x16AWG)?
I was unable to find the 4s8G online and only saw the 4s8 (which is *not* oxygen-free copper conductors), is that a big deal?

Is there any reputable dealer which is selling it pre-wired or that I will have to do it myself?

What's wrong with the old cables?

They are generic cables I wired under the floor as part of a major renovation 6 years ago.
The cables were supposed to be a temporary solution until I will get something better (the contactor called asking for cables within 24 hour before he closes the floor so I took something from the nearest HW store) , but there is nothing more permanent than a temporary solution ...

SInce then I replaced my AMP and it now has a speakon connection I wish to use.
I also noticed that some of the banana connection are getting a loose contact with the speakers so it is really a time for change.
I can simply install speakon connector (about $10 a pair) and maybe redo the banana connection on the speaker side, but I don't even remember the spec of the temp cable I used so better replace the whole thing and be done with it once and for all

I doubt there would be a difference between the 2 canares.

Cut the ends and redo all the connections on what you have.
That would be my advice.
