What would be the simplest way to amplify the signal traveling through a 3.5mm audio cable?

In case you'd like a little more info:
What I'm trying to do is set up a PA system in my van. I thought the best way to do it would be to use my car speakers via my cassette player. Obviously, though, if I hook a microphone directly up to a cassette adapter, the signal won't be strong enough and even if I turn the volume all they way up in my car, I doubt it will be sufficient. What gadget could I use/hack in order to strengthen the audio signal. If I get something to accomplish that task, I think I could wire it up to my cigarette lighter and I'd be all set.

(My experience in the area of hacking gadgets is almost non-existent so I'd appreciate it if you'd keep your answers simple, and if needed, provide links to places where I can learn what I need to know in order to accomplish this.)

Thanks in advance to anyone willing to post their suggestions!
