I have 2 10" 4 ohm speakers, I am trying to hook it up to a 2 channel amp, how to you wire the subs?

I have these subwoofers (2 of them) http://www.crazystereo.com/memphis-15mcp10d4-p-2180.html and this amp http://www.memphiscaraudio.com/products/amplifiers/class-d-power-reference-amplifiers/ (1000 watt version) I have everything hooked up correctly on the amp and everything is on. The only issue I am having is that... its about as loud as my cell phone. I did however have to look up how to wire a 4 ohm subwoofer. Can someone reassure me on how to do that? I have 2 voice coils on the back of each subwoofer and a 2 channel amp. This is the first time I have ever hooked something with 4 ohms up so there is a high chance that the subs are hooked up wrong. SOS?
