Power testing an actual speaker terminal?

I know it might sound strange, but I want to power test a spring loaded speaker terminal. I can't test across a real speaker load. The actual box is ported and is using a 1 ohm speaker. Power handling of the speaker box combination is 1000 watts RMS. I want to see how hot the terminal gets over time. This to include the metal parts and surrounding plastic. My goal is to best simulate what the terminal see's using a pure restive load and some sort of repeatable electronic tone or tones. I understand music & a speakers real reactive load is different. However I would like to get as close as I can? Should I look at a mean average and pick a resistor value that way? I worry if I use a 1 ohm resistor the constant current is not realistic?? It might be possible that I could use music on a pure restive load?? On a music signal what might be a best choice? As I remember Amir spoke about a site once where you could load music and look at its spectrum?? So do I want a high average and a high crest factor or WHAT????......................PLEASE HELP??

Any testing at the 1000 Watt level is dangerous.
But a big 15 Ohm resistor or a room space heater and 120V AC power might do.
