Pioneer speaker plugs

I picked up an old SX-828 at a yard sale. The guy told me 'parts only, don't even plug it in' but of course it powers up beautifully, lights work, etc. Now I want to see if it actually powers anything but I've got these weird speaker plugs that look like outlets. Googling suggests I could just shove speaker wire into the hole for testing purposes. Is this true? I don't really want to spring for the adapters since they cost more than the amp did and I don't know for sure that it's fully functioning.
 
I call them Zippy Plugs. Whoever owned this before probably found the trick here on AK. The problem at hand is to figure out polarity. You have to pay attention to which way the wire goes in the hole. Do that and you are golden. Nice find by the way.

You can get them on line,I went to the hardware store bought male wire connectors filed them to fit crimped to the speaker wire and all done cheap

Top slot is +...but of course that's irrelevant as long as you wire both speakers the same way.

Here is a link to a cinch connector that can be easily modified to fit perfectly...just remove the center pin (takes about 30 seconds). I recommend wrapping them in electrical tape to assure that the two connectors cannot make contact with one another after being plugged in to the receiver.

As to the original question, yes, you can just push wire into the slot for testing purposes.

There are a number of long term ways to go afterward.
 
Yes...thought that was apparent from first response. To the OP....as noted, connect both speakers the same way, and make sure that the bare wires are not so loose as to easily pull out and short to one another or to the metal case.

If you care about the speakers you are going to use to test the receiver, and if you have a multimeter, you might want to think about checking DC offset before plugging them in. Easy to do....here are great instructions:

DC offset results are kind of like taking one's temperature or checking one's pulse....won't tell you what the problem is, but if out of whack, you know something is wrong.
