I pulled two small speakers from a laptop. 4ohm 2watt. I was wondering how to power them properly. Im 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 it wired both speakers are 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.
