To just use these XPA amps to run a stereo pair of speakers is not as complicated as it first appears.
The reason we have to search for the little plastic terminal blocks that plug into the back is because when the "pro" installation monkeys remove them for an up-grade, they don't take the time and care to perserve them. Or perhaps reuse them when possible.
The 2002 you linked is a little different than the 2001 I am using and uses different pin configurations, but they are avail. Here's the ones you will need.
Inputs would be;
Phoenix Connector. 3.5mm Pitch. PhoenixPluggable Connector.

The speaker out-puts would be;
Pin pitch : 5.0mm / 5.08mm. 2 Pin - 5.08mm Connector.

The nice RCA adaptors Rooskie linked will not work on the 2002.
After you get the the terminal blocks in hand, one end of an RCA cable needs to be lopped off and stripped down to bare wires so it will go into the terminal slots. It sounds harder than it is and yours would be more simple yet as there is no cross-channel balancing. The biggest prob. I had concerned my fat fingers.
Here's a YouTude vid that sort of covers what we are talking about;
Here's the users guide for the amp;
I've learned a couple of tricks on doing this and if you buy it, let me know and we can go over them.
<<<<<Also, Amir mentioned programmable gain, trigger settings, etc. Is software needed for a simple stereo setup?>>>>>
No programming other than flipping the High-pass (@ 90 Hz) switches on if want them. Gain is two screws if the back, I run mine full up, but it has half the power of the 2002. The trigger is for big system installs where the unit is unaccessible. It turns itself off after idling for a while and comes on w/ an auto function.
Besides sounding great, these things are tough as nails. You can't hurt it by crossing wires as it has very good protection. I would imagine the vast majority of used ones are fine. Plus the vendor you linked has a return policy.
The price looks good, so I would say go for it.
You do understand you will need something to control the volume? And if your source is digital (No point in using this amp if it's not), it will need a DAC in front of it. I'm using a receiver with pre-outs, so I have a built-n DAC, tone controls, balance, along the Vol. But my speakers are good enough that don't really need the tone controls, so a external DAC like the Topping SU-6 would work as well. I suspect the Revel 12's would be the same.
