$800 on subs+enclosure, $60 on amp.
Why pay top dollar for some equipment, and then low ball the rest? Even though the kickers are worth NOWHERE near the money that site wants.
If they set prices, they will end up being higher. If you want to pay more, so be it. I'm perfectly content with the way things are run now, as are many others.
No one has suggested a DDW6.5 in a .5ft^3 enclosure yet? It will fit your budget, be plenty loud enough for your needs and be badass, all the while taking up little space...
