STINGERSK6681 8-Gauge 6000-Series Complete Amplifier Installation Kit, Blue

Does this kit come with speaker wires? And if so, does the kit come with enough speaker wire to connect the front pair and rear speakers to an amp?

I have a 4 gauge on my 4 ch, can i use this for a mono amp(audiocontrol acm-1.300) just wondering if i should use the 4 gauge instead?

What is the interconnect wire for?

Is this ok for any amplifier ?
