# Can You Play Audio Over a PA System Using a Phone?

In summary, the speaker is asking if it is possible to use an aux cord connected to a phone or other device to play audio over a whole PA system by attaching the stripped ends of the wire to the speaker's plug. They are also wondering if the signal would be strong enough without an amplifier on the input end. They are asking if it is hypothetically possible to use one of the outputs of an audio system as an input. The speaker suggests asking a science teacher at their high school for more information.
I know relatively little about electricity so this might sound kind of elementary. Say you have a public address system installed in a building, and someone is trying to do a prank that involves playing audio over the loudspeakers. Each loudspeaker has a signal (positive) wire and a ground (negative) wire. If you disconnected one of the speakers and attached the stripped ends of the two wires to the plug of an aux cord connected to a phone or other device, would you be able to use the device to play audio over the whole PA system? From what I understand, a PA system usually has to have an amplifier on the input end to boost the signal from the input; if you were to use just a phone/iPod on a large system, would the signal not be strong enough? I guess what I'm asking is whether you could hypothetically use one of the outputs of an audio system as an input.
