For poops and laughs, we will call this a 4 ohm nominal speaker, which it is, depending on where you looks. So, this means each speaker is going to receive the amp's potential of 100W rms each, 400W rms total. Set to hi-pass and about 120hz and gain set right, you are getting about all that setup has to offer.

Sticking with that amp, I would suggest 2 pair of 8" coaxial, like the Kicker KM8. You get added mid-bass as well as output. Added benefit, they come loaded with RGB LEDs that you can leave unconnected, connect single color red, blue or green, or with all 3 and add an RGB controller.
