to be honest, with your first system. start small. and eventually maybe 6 weeks, or maybe 6 months down the road you wont be satisfied and you will upgrade. and from there on it endless upgrading.
i would personally look into an alpine type r of 1000 watts. when you start there, its decently sized. will definately give you some "thump" and is realatively cheap.
with 1000 watts, your not gonna have to worry about electrical upgrades (even tho the big 3 would be great, but thats a different discussion and theres a sticky on it so search)
but look into an alpine type r, i would get a one of them in a 12", and run it off a hifonics bxi 1210d
get a 4 guage amp kit off
ebay, personally i would piece it together through knukonceptz as they are very reasonable

http://www.sonicelectronix.com they usually have good prices and shipping is pretty fast.
i think that would be a great starting point, and i would buy a prefabricated box first to start you out, then when you wanna upgrade. the best upgrade you can do it build a box to specs, and then the sub, then the amp.
search around, and utilize the search feature in the toolbar towards the top of the page.
