I need help building a 700+ watt sub amp

[bucknasty]

I'm new to this site, I har been currently been building my own cabinets for a few years, but I'm wanting to start putting amps inside them so I don't have to carry a rack anymore. I'm wanting to experiment and learn about audio electronics. So what I'm asking for is help building an amp that can easily handle continuous 600+ watts that plugs in a 120v and have 1/4jacks, basically a plug am play setup. My skills consist of basic electronics and small repairs. I own all the tools except an oscilloscope. Please help me.
