I don't know much about Audio in general so this may seem like a simple question but... My wife got a Stage Speaker from her dad that she wants to use on her Karaoke machine... The speakers inside are Celestion g12m-70 @15 ohm impedance. The type is T3577 if that makes any difference. It has 2 - 1/4" jacks as input. No Power input. I know I have to run the Karaoke output (3.5mm headphone jack) to an amp and then to the Speaker set. My Question is what's the easiest and cheapest way to do this. They're primarily drunk when the sing so I don't think super high quality is required. I was thinking that I might be able to use a car amp to power it but 15 ohm impedance is fairly high isn't it?
