Sub cable length?


Should I match the length of my speaker cables to the length of my high-level sub cable?

I’ve got an LFD/Mistral amp with LFD Spiroflex Speaker Wire (3 meters) to B&W 805’s and using a REL S/3 SHO sub with the stock power and speaker cables. I was going to get a Snigal Cable http://signalcable.com/relspeakon.html and was unsure if it made any difference between the standard 6ft (which is plenty long enough for my needs) or get a 10ft to better match the 3-meter speaker cables.

Thanks!

And sorry if this was a dumb question, I didn't find this in any past threads.

Electricity travels at the speed of light, not much time difference between 6 feet or 60 feet. 
Doesn’t matter.  Keep in mind that the sub’s driver is in a physically different box, therefore, it’s already not time aligned with the main speaker’s drivers
Hi Colindshots!  All the responses so far are fine. but not specific enough for a newbie. Length is not a problem; just use 14 gauge, or heavier (lower numbers). I have used 14 gauge solid core wire in 70+ foot runs in auditorium installations with no problems. 14 gauge lamp cord will do. Happy Listening!
