whats "budget" to you? and i'm guessing they are dual 4's right?
if they are, I would wire them up to get a 2.6 ohm load. so look for something in the 4-500ish watt range at 2 ohms. that should be good for you.
I have a basically brand new Kicker XS50 I can sell for that it was mounted to an amp rack but never seen power.....It is a US made Kicker...comes with endcaps and badge....
