Well if your looking at that kind of power...
1) You will need to do entire Big 3 with 4 Ga wiring
2) Extra battery is pretty much necessary- or a larger alternator
3) 1/0 wire to the back.
At the end of the day you want an amplifier with enough headroom to do what you need without maxing itself out.
American bass VFL series provides a competition quality/duty amplifier at a decent price. There more flexibility also...

That would run $300
A little more tame would be the 80.1 for $200

1/0 wiring kits for $80
I also have the Crunch 1500.1 Available for $140
I have the Brutus amp also but my pricing is not competitive on it.
The Brutus amp is a decent amp, will do what it says.
For $200 though your budget is pretty weak. Especially if thats to include wiring.
Remember, you get what you pay for!
