Sooo.... I did it today... and the sound is actually very good -- I got caught in the rain so did not get to tune the amp, but I was very happy with initial outcome ...
Here is what I did --
- spliced into the rear speaker for line in using this LOC:

- I used a 12 gauge cigarette lighter extension and cut the other end to feed power and ground to the amp:

- I ran the wire under the seat cushion straight into the hatch
- I plan to hardwire it to the cigarette port if I'm happy with this setup + I plan to add a fuse at the start of my line + I also will drop in a 10A fuse for the aux in place of the current 20A to be safe
- I used the same power wire as the remote switch (and tested that it indeed does power off after 30 mins after ignition is turned off)
- I have to play with the amp more to remove some of the highs coming through, but when i just dropped the filter to 70hz it sounded great
- This is the sub/amp I am using:

I know this is not a conventional setup, but honestly I feel it sounds very very good compared to stock and is a pretty clean install. I will take pics once the rain subsides and I can make the wiring a bit nicer..
A couple of questions for the sound gurus here:
- Is it better for me to feed speaker inputs straight into my amp's 'high level input' OR am i better off using the LOC that I linked to and feed into the amp's RCA line in? (edit: did some quick research and overwhelming advice on the web is to use high level input on the amp instead of an external LOC so i will change that with my setup..)
- For the remote line, I just bridged it to the power in with a small wire -- is that acceptable since the power is switched?
