Step 2: Mono and Stereo at the Same Time

If you’ve already got an audio cable hooked up from the DVD player to the TV set you’ve got a couple of choices. You can disconnect the audio cable from the DVD player to the TV and hook up your computer speakers (no sound will come out of the TV’s speaker), or use a splitter so the mono audio still goes to the TV while the stereo audio goes to the speakers. An inexpensive RCA Male to two RCA Females splitter will do the job. (An adapter changes one type of connector to another while a splitter takes a signal and splits it into two identical signals.)

My preference is to use the splitter because it gives extra flexibility. If I’m just watching an ordinary DVD then I’ll just use the TV’s built-in speakers and leave the speakers unpowered. But if it’s an action movie with lots of audio effects or a musical I’ll turn on the external speakers.

The first photo shows a gray colored splitter cable plugged into the DVD player’s white (left/mono) audio jack. The white cable from the adapter is plugged into the splitter and the red cable on the adapter is plugged into the red audio output jack (hidden underneath the gray splitter cable in this photo). The speakers are connected to the other end of the adapter. The other half of the splitter sends the left audio channel to the television, along with the existing yellow (video) signal.

Hooking up external speakers to your DVD player has an added bonus; the DVD player can also be used as an audio CD player. Just leave the TV set powered off. Put an audio CD into your DVD player and you can listen to CDs through the stereo speakers.
I have a few of these reused setups around my house.I didn't pay more than$6 each.But I only buy the ones with internal power.<br>A JBL system in my workshop with an old android phone as an internet radio/dlna reciever with an added usb charging port.<br><br>An Altec Lansing system in my garage with a Bluetooth a2dp reciever wired inside it,$12,30 watt stereo Bluetooth system.<br><br>And a nice Logitech system that's going out on my deck,internal Bluetooth of course,as soon as its done.<br>The price is right!<br>
<p> Philip, </p><p>I need your help. I want to add wire to my existing mini stereo speakers so I can put them on top of the entertainment center instead of right next to the stereo amp. I have speaker wire and I have 22-16 butt splice pieces. I will have to strip the wires at both ends, insert into butt splice and really crimp them hard to get them to stay in there nice and solid. My question is what do I use to make a good solid crimp. Wire strippers or something else. When they are attached to the stereo they just go thru a hole and close the pin and they are attached.</p><p>I would appreciate your help on this because I don't want to mess up the butt splices. </p><p>Thank you in advance for any help you could give me.</p><p>Glenda</p>
<p>OK thanks for the demos. BUT your link to <a href="http://www.neatinformation.com/howto/reusing%20speakers.html" rel="nofollow">http://www.neatinformation.com/howto/reusing%20speakers.html</a> is no longer working. Please either update or take it down.</p>
<p>I don't get this. It's like an instructable on spoons and how to eat soup or ice cream with them.</p>
<p>Maybe for you, but not for others. I've shown many friends how to use used computer speakers to add stereo to a DVD player, a speakerphone for a smartphone, etc. and they've all appreciated the information instead of making a snide comment about teaching them how to use a spoon.</p><p>Also, an extremely high-tech gamer friend was astonished when I suggested that he add a pair of speakers to his computer for surround sound - it just never occurred to him!</p>
<p>To me it's really pushing the limits of spam,trying to get everyone here,and also anyone who may link to here,to redirect them to neatinfo for web traffic revenue.</p>
Great instructables, I've picked some really cheap and great speakers on goodwill stores and yard sales. <br>As a tip: some old compaq speakers (around 95 to 99) have JBL 4ohm drives on them. <br>Im actually building a hi-fi stereo amplifier using 2 brideged Tda40 IC's for running 6 of these speakers. <br>
I totally agree with you -- used pc speakers are the best buy out there for low-cost audio, and I've picked them up used for as little as $5. Not only do I used them on my computers, but on a dedicated internet radio, an mp3 player, and for the audio on a talking robot head that I built. They can also be disguised, as in an instructable I did some time ago: <br><br>https://www.instructables.com/id/Vintage-Speaker-Cabinet/<br><br>Nice job on the instructable!
Thanks. I see them all the time at $5 - and at this point I think that it's too much(!). I've got about three spare pairs of speakers in my workroom ready for projects, so I only pick up additional ones if they're $3 or less unless they're extremely decent ones.<br><br>I did pay $4 for the 2.1 subwoofer + 2 speakers I mentioned in the instructable, but only because it had the subwoofer and had two sets of inputs.<br>
