I’m confused

Hooking up Coolmusic amp to Alesis Edrums!

I’ve been using my Alesis Nitro Kit with headphones for a few months now. I finally decided I didn’t want to deal with the headphones anymore, so I bought a CoolMusic amplifier off of Amazon. The only pieces that came in the box were the amp itself and the wall cord. Great. I plugged the amp in and flicked on the power switch and nothing happened— no blue lights, no static sounds, nothing. So, where do I go from here? Should I send it back or am I doing something wrong?
