In all honesty you don't need to do a lot for the electrical upgrade here! Your only going to be running one amp for now. The 13w7 is a great choice for your first sub, but you won't want to go anywhere else after it lol.
If you have an optima just do the big three and you'll be fine. You MIGHT get minor dimming and thats about it.
For this system you don't need to upgrade your alt and everything. But I highly recomend your run 1/0 gauge wiring for that 2000 watt amp instead of just a 2 gauge.
And for your second setup or #51 those are all extremley good choices!
Another thing is, go out to one of your local shops and just listen to these subs! See if you like them or not!
