i already have all this stuff but im upgrading my cheap wiring after it shorted my Subwoofer amp thank god it was covered by the warranty , im little concerned where to find an existing hole to run a 0 gauge cable with about 3 mm more bigger because im going to cover the power cable with cable hosing , do i need to drill ? + the true wattage of my system ohm's is going to be about 750-800 watts max do i need to do big 3 upgrade or add cap or im going to be fine , im replacing my stock head unit with Kenwood DNX6190 , BTW how is my build ? thanks in advance

Most of time I will drill a new hole in the firewall and use a rubber grommet, especially for 4ga and larger.
When adding any decently powered amp, you should always at minimal upgrade the ground cable from the battery.

How does that help him?

As far as the Big 3, why not. It can't hurt anything. Like JK said, just find somewhere and drill a new hole and plug it properly.

There is a little piece of plastic on the inside, next to the brake pedal, where the clutch pedal gets installed for manual trans vehicles. It is pre-cut and has a tab you can grab to remove it. It's where I always drill for new power cable
