Long runs with no issues.
Color: 14 AWG, Size: 500 Feet
This wire drives my 100 watt system with no sound issues, very flexible and the right gauge wire for my system and long runs.

Not sure if these are truely 14 guage.
Color: 14 AWG, Size: 20 Feet
I think that the wire is good quality, but I wound up using some wire that I already had after stripping some of this back and then comparing it with my old 14 gauge wire. I did not get out a caliper and measure it, but by feel and visual comparison it did not seem to be as heavy as my old wire.

Easy,affordable,quality, double protected
Color: 14 AWG, Size: 20 Feet
I used this to hook up two old school P2D2 12” subs and I am beyond happy with the wire. I tried a lot of wire over the years but this is the one you want!
