I'd suggest a hundred feet of 1/0 wire. Two hundred feet of 12 gauge wire. An alternator that puts out at least 240 amps and if you can put two or more under the hood that would be best. Two bats per bass amp and one per mid/high amp. Three 15 foot high quality rca's and twelve 6 foot high quality rca's. Then spend the rest of that money on sound deadner. The one thing with car audio is no matter what you got it's gonna sound like shit to you in a week. So set up you're ride to accept what you'll buy in the future. Don't forget the big three, a good multimeter, a RTA, and access to a decent o-scope. You'll end up doing this all when you get the bug anyway.
