Were can i get one speaker wire on one end an plug on other end

The connectors are binding post or banana plug. I would use speaker wire and connect the speakers and on the back of the receiver. Refer to instructions page 20. You bought the plugs so who is to blame?

If it's a power cord, it doesn't plug into the computer; one end goes in the wall, the other into the speakers.

For most speaker pairs, there are 3 wires:
1) The wire that connects the speakers to each other. That's often fused into the back of the left speaker, and gets plugged into the right speaker (it's usually pretty well marked where to plug it in).
2) The wire that connects the right speaker to the computer. Usually it's pretty well marked where to plug this into the speaker. On the computer, that wire will fit into 2 ports. Usually those ports are marked with microphone and headphone icons. You want the headphone jack. If they aren't marked, try them both or check your manual.
3) The power cord. One end of that will plug into an electric outlet on the wall (or into an extension cord or power strip). The other end will plug into the right speaker; it should only fit into one hole (which will probably be marked with "12V" or "0.5A" or something like that).

It would help if you told us what kind of speakers you have, and what kind of wires you're seeing.

Radio shack may have a replacement end to fix it with.

Hi.
Even though you may need to put new plugs on the ends of the wire, you can still use the wires without having to go out and by new.
Places like Radio Shack, Fry's, Ovation, BestBuy, and CompUSA all carry wire plugs that you can install yourself rather easily on the old wires to make them work with the Bose receiver.

Putting plugs on the ends of the wires is really a simple thing to do.
Just follow the instruction that comes on the pack, and you should be fine.

I don't blame you for wanting to utilize the old wire, it can get expensive to replace speaker wires.

The plugs are a cheap way of saving wire, and saves you quite a good deal of money as well.

I hope this helps you out, and good luck !

The cord or plug in is damaged and needs to be replaced from end to end just get some wire and open the speaker case and redo the wires. This is an easy fix, find another cord matching and just solder a new one from end to end with a new tip. That is all you need to do? Thanks for using FixYa! John

Connecting Full-Size Speakers
1. Step 1 Insert the red and white plugs on a set of RCA audio cables into the right and left audio "OUT" jacks on the back of the TV.
   
2. Step 2 Connect the other ends of the cables to a free pair of audio "IN" jacks on the amplifier.
   
3. Step 3 Strip 1/2 inch of insulation from the speaker wires, and connect a pair of wires to the left and right terminals on the back of each speaker using the red wire for the right audio connection and the other wire for the left.
   
4. Step 4 Connect the other ends of the speaker wires to a pair of stereo speaker terminals on the back of the amplifier. The wires attach by raising spring-loaded clips on the back of the amp to reveal a hole for inserting each wire.
   
5. Step 5 Set the amplifier selector to the set of audio jacks connected to the TV to enjoy stereo sound from the television.
   
Connecting Self-Powered Speakers
6. Step 1 Insert the RCA plugs on the Y adapter into the TV's Audio "OUT" jacks.
   
7. Step 2 Connect the mini-plug on the wire attached to the right-hand self-powered speaker to the mini-plug jack on the Y adapter.
   
8. Step 3 Plug in the audio cable and mini-plug from the left-hand speaker into the Audio "OUT" jack on the back of the right-hand speaker.
   
9. Step 4 Connect the AC adapter to the power jack on the back of the right-hand speaker, then plug the adapter into an electrical outlet.
   
10. Step 5 Switch on the external speakers and adjust the volume.
    

Depending on the sound card installed in your system, integrated into the motherboard or not, you may need a "Y" splitter adapter. Typically, the subwoofer has a black plug while the regular speakers have a green plug. The red color is a new one on me, but let's assume that it is the subwoofer. If you have a black outlet on your computer, plug the red one into that outlet.

If your speakers came with your system, HP would have provided you with proper adapters to make the speakers work for whichever speaker system you have. If you have any "Y" adapters, use them.

The black wire goes in the external speaker and the red wire goes in the PA jack.

If you have bare ended wires , you simply unscrew the red and black plugs at the amp they should have a hole in the end of the plug and on the side also just place the red wire into the side hole of the red plug and finger tighten the red screw the same on the black plug

I am guessing you mean the cord that goes into the PC, I don't know how "Broke"it is, but you should be able to cut the old end off and replace it, if you buy an inexpensive speaker extension cable, you can use that for the new end, or try radioshack, they may have replacements that just need to be wired, usually a black and red wire is all, just tape it up good to avoid shorts
