I don't have the AC DC 12V in (power cord). What kind is it?


Not only do you need the correct voltage and amperage (MAH) but you need the corectly sized plug to fit the socket AND it has to be in the correct polarity. Usually the polarity is marked by a broken circle with a dot in the middle. Leading to this dot will be an arrow or just a line and at the other end of the line will be either A positive (+) or negative(-) It's important you get this polarity correct when plugging a new power supply in.

Your local electrical store should be able to sell you either a fixed 12volt supply or even a variable supply allowing 3, 6, 9 or 13 volts output. Make sure it has the amperage capacity you need. It won't matter if you need 500Mah and the supply is 750Mah as long as it isn't less than what you need.
The power supply should come with an assortment of plugs which are insrted into the socket on the end of the power supplies lead. Follow the instructions on the packaging and ensure you have the center pin set as either + or -. If you are in doubt. Take your speaker which has the socket fitted and show the salesman. He should be able to pick the correct plug and make sure it's the right way around.

If you plug it in and nothing lights up, quickly remove the plug and turn it 180 degrees in the power lead socket. Obviously it's been put in the wrong way round. If you were quick enough no damage should have occured and away you go.

Just one tip. Wrap a small piece of insulation tape around the plug to stop it from being pulled out of the power lead's socket. They do tend to work loose after a while. Oh and make sure it's switched to 12 volts if you get the variable one.

I need a new plug for 12V in AC/DC


I will presume you mean power supply

In which case a "universal power supply" will do the job fine so long as you remember 2 important things.

1. Voltage this you already know and lots of universals go up to 12V

2. Current rating. this is just as important as 1. check on your speakes or old PSU that information should be on there somwhere nd itwould lok like 250mA or 500mA or whatever the rating is. it is important to make sure that your replacement is the same or even a little higher if your speakers are 250mA then it is safe to go to 500 mA.



If you just want to solder a new end on then radio shack, tandy, the source are just a few of the places you will find what you want.

Do I need a battery? What is my power source?


Well first off if there is a power cord that goes in the front then it should be powered by that. Second of all you should have a power switch on the front of the speakers to turn it on and volume control.

Can i power my 12v computer speakers with my computer power supply


Generally NO.  Most computer speakers are self powered.  The speaker output from the computer is only enough to power headphones.  However, you can plug that into a stereo and then use the speaker attached to the stereo output.
