I just want to make sure I have this dead right so I don't destroy anything.
I have this subwoofer. Precision Power PC102 Dual Voice Coil.
I have this amp. Phoenix Gold Octane R 2.0:1
Do I wire it up like this:

or this?

well since your sub (from what I can make out) is dual 2 ohm voice coils
IF you amp is NOT 1 ohm stable then you will need to wire them like this:

IF you amp IS 1 ohm stable you can wire them like this :

unless I am mistaken and your sub is the dual 4 ohm version
IF you amp is NOT 1 ohm stable then you will need to wire them like this:

You will more than likely have to wire your sub like this

But your amp will not be pushing 200W in 4 Ohm load. It will be pushing half that which would be 100 W max.
To get the most out of your setup, you would either need to buy another sub so you can wire it to 2 Ohm or buy another amp that is 1 Ohm stable.

Alright. I'm not worried about it not being loud enough for me...I'm sure it will be plenty. However I have heard that you can damage subs by under powering them. I am not underpowering it enough to cause any harm am I? I just want to make sure...

I grounded mine to the same flange that the antenna is mounted to. Its a pinch in the metal that goes over the wheel well.
Any decent thickness metal should be fine, just make sure there is nothing behind it that you could damage if you drill a pilot hole and make sure to clean (sand) the area free of all paint/rust/other.
Attempt to make your ground wire about 2 feet. A little longer wont hurt, but dont leave a spool in your trunk. That is just asking for interference.
