I haven't done it personally, but based on the wiring diagrams, I assume that the input to the Sony DSP/Amp is a full range, stereo low level signal. That is exactly what you want to feed an aftermarket amp, and without the need for expensive processors and the added noise of amping and the lowering the signal.
If you decide to stick with just working with the sub, you're actually lucking out. You can install an aftermarket amp, box, and sub without even taking out the head unit. The Sony system sends a low/RCA level signal and a turn on back to the Sony sub. All you have to do is add a RCA jack to the end of the signal wire and add a relay to use the 5V turn on signal and you're good to go.

Ok. I could live with just an upgraded sub and continue learning about the other stuff as I go. I'm guessing I can just buy some RCA cables that only have the jacks on one end? I know I've seen a wiring diagram somewhere that shows which wire does what. I think I can figure out a relay for the remote turn on but is it possible/safe to run the remote to a fuse?
You can just cut the end off of an old RCA too

I would use the Turn-on/enable at the sub to throw the relay, and use the stock sub power as the 12V+ for the relay to turn on.

ok so i looked at that diagram of sub wiring and i see the ground on my harness (black with yellow stripe) and others arent exactly the same color but i think the sub negative is the lime greenish wire. in the diagram it shows more of a darker green. what i think is the positive sub is the purpleish on on the top right on the picture and assuming the pinkish grey one on the left is the "enable" wire. Now, that would leave the light blue wire as the power wire? i think i may be off on this but heres the picture of my wiring harness.. maybe you could set me straight

Look at the letters on the wires in the diagram. They are for the colors. For example, power is Brown w/ Red Stripe (BN-RD), that's the far left, It also says it's pin 5, the far left is pin 5.

Does anyone know if there is a wiring harness adapter for the sub connection that would be open on the other end. So I could make my connections without cutting off the stock harness. In case I sell later
