Solved! AUX to amplifier?

[lorderi007]

I don't really know how should I use my phone to input sound into my subwoofer.
I currently have this mono amplifier.

I'm not sure what I should do. What is the best way to use my subwoofer with my phone?

Thanks for the great picture but unfortunately u were not that specific with WHICH phone?

One way is through the headphone jack I suppose.
