I just want to make sure I don't make a mistake.Can someone please tell me which way to properly hook speaker wires up?Everything is vintage,Sansui G901db to Pioneer cs99 speakers.On the receiver it has two connections,two terminals 300,and one terminal & ground 75 (both FM).Also,I unscrewed terminal connection on back of speaker to much and the stud the nut goes on is now recessed and I can't get nut back on.I'm very inexperienced,any help is greatly appreciated..

Speaker connectors are on the left (if you are facing the receiver). Those are the black and red spring clips. For two speakers you will only use one set. Just make sure you are connecting left speaker to the left output from the receiver. Also observe the polarity (red wire from speaker to red clip in the receiver) and you should be good to go. Of course turn everything off before making any connections.
Note the speaker connections on the left-hand side of the receiver as mentioned (where the cables are connected in the bottom of this photo).
Be sure to keep the connection red on the receiver to red on the speaker, this is known as keeping the speakers in phase (more on that later
).

Use good quality speaker wire. I suggest 16GA at the minimum, depending on how long the run is. I might be just me, but I like each wire to be approximately the same length. Don't have a 4 ft. wire on the left channel and a 20 ft. wire on the right. It has something to do with resistance within the wire. Good speaker wire is usually marked in some way, possibly little + signs or a white stripe on one conductor, Sometimes one conductor is silver color and the other copper color. Keep the phase (polarity) matching on each speaker. The wire I use has a white stripe, which my rule is white is the new black. That just helps me keep it in phase when I swap out amps or speakers. Enjoy.

I am not a Sansui guy per say. I don't have any machines with the speaker terminals on the side. What is that amp? I like how you have the speaker wires banded on each end with colors. I like using banana plugs, although they don't match up to many vintage speakers without a homemade adapter.
That is a picture of the receiver in question, not mine, just one I found on the web with a shot of the speaker cable connections.
Wow,you guys are great.My son was supposed to post a picture of the speaker connectors,he forgot.I will get him to do that.How would you guys hook up the antenna,300 ohm or 75 ohm,does it really matter?I will be asking questions about a lot of differant things,I will try not to act like a dummy.Thank you all very much.

Yes it matters, unless you are in the city with lots of strong FM signals ...
I use 14ga lamp wire for all my first test speaker installs. It's readily available in black, white or brown, so you can usually get it hidden'ish along the baseboards and such.
If you look closely at the wire, you will see that one conductor has a smooth jacket and one has a ribbed jacket. I traditionally put the ribbed side into RED on both the receiver and the speakers

Ouch... The red terminal is broken off, so unless you replace it, you're not going to be hooking up a set of regular speaker wires to that. Is the other speaker in the pair in similar condition?
You can still hook up a stereo (read: both channels go through one wire) 1/4-inch cable to the "INPUT" jack above the two terminals (also called "binding posts"), if you have the correct wires to convert from standard RCA to 1/4-inch, or if you have an amplifier that has 1/4-inch output ports, just to make sure the speakers function.
Any more photos? What's the general condition of the speakers?
If/When you do decide to replace the binding posts you can get them from a whole lot of places. Parts-Express (no affiliation) has plenty to choose from, as do quite a few other suppliers.

Hey, this is his son... It didn't break. it was just unscrewed too much and it came out. The stem went into the speaker. We tried positioning it with it's back down to see if maybe it would stick back out, but it won't... it's like its on a spring or something that's keeping the stem inside.

Just an old fart trying to help.
Is the red "stud" simply recessed into the speaker or is it snapped/broken off?
If it's simply recessed, you may need to remove the woofer to access the crossover, then simply push it back out far enough to start the threads on the red screw cap onto the stud.
If broken off there are other options but each may require some additional parts.

OK--OPs son posted as I was writing...possible solution in my previous post.

Hey, a father-son operation! I'm "Son" and @Charles218 is "Father" in our own one of those. I like it!
Sounds like it's time to open 'er up! Most likely there's just a nut+washer combo on the other side of the post that got a little too loose, OR it's just that the red plastic part of the post was screwed off "too far" and the threaded metal piece fell into the cabinet. Even if neither of these are the case, at least you know where the other part of the post is - it's inside the cabinet.
More photos are always extremely helpful!

Order of pics:
1. Fronts (The white on them is just packaging foam)
2. Backs
3-5. Back of the one we unscrewed too much.
6. The knob, stud, I don't know. lol.. The washer came off with it.
7-8. Back of the one that already didn't have a knob.(This wasn't known until I mentioned it earlier)
I hope they stay in the order that I pasted them. The pics where the stem is out is the one that came without the knob. Pics of the stem inside is what we unscrewed too much.
