Answer 1

The load ratings on amp install kits aren't usually very accurate. If it is an 8 or 4 gauge cable, I would replace it.

Go with a 2 or 1/0 gauge kit. This might seem like a bit of an overkill. But, like I tell everyone. If you lay the groundwork right the first time, You won;t have to tear it up late when you want to upgrade.  

Answer 2

No, you don't have enough power, but you can sure as h**l try.

Answer 3

yes you can those watts posted are peak power stats..  the rms wattage is less than half that so youll be fine

Answer 4

You can use them, but you won't get the most from your equipment. However, I don't think anyone will be able to tell the difference, it will be minuscule.
