I have two Pyramid PW677X 6-Inch 300 Watt Subwoofers and I am looking to get an amp.
I am not sure what amp to get. I will only be powering those two amps not speakers. Since the subs are pretty cheap I am not looking for an expensive amp
What do you mean "you will only be powering those two amps"?
And good lord those subs look awful. 6" sounds more like a midbass as well. Anyways, they are rated for 150wRms and single 40hm voice coil, so you'll need something that does 300w at 2 ohm.
