I pulled two small speakers from a laptop. 4ohm 2watt. I was wondering how figuring I need 9v total. I was going to use them in a set of custom headphones. They work great when plugged into a pc but when plugged into a mobile device the sound is horrific and I hear no voice. I have connected via 1 wire, and both speakers have one wire going to the plugged.

Any help is appreciated. Im starting to pull my hair on this.

Well, the cable you have connecting the speakers should have three wires to connect, if you are connecting from a portable device.
 
two for the left and right "positive", respectively
 
and one for both "negative" connections on the speakers.
 
Usually there are two wires inside a cable, and a whole bunch of bare wire that surrounds the two plastic-covered wires inside. The bare wire would connect to the minus, or ground.
