You can't go wrong with Pioneer

I have this amp wired to 4 Hifonics 3-way 6.5's and this amp makes them sound pretty good, I'm actually surprised this amp hasn't blown those speakers considering the power it's putting out. Gonna order another one of these amps in the near future so I can put on a set of Pioneer 5-way 6x9's to complete my audio system.
