I just bought a new alpine speaker component set. The speakers i bought were the Alpine Type-S SPS171A. I would like to know which amp(a decently good one, at a rsonable price) would be ideal for this component set. I want them to pump to their full potential. These are some of the specifications of the set:

Sensitivity 90 dB
Frequency Response 35 - 30k Hz
RMS Power Range (Watts) 8-50
Peak Power Handling (Watts) 250
Impedance (Ohms) 4

Any help is greatly appreiciated.

Check the Arc Audio kar200.2, there good amps. My sister runs a Arc kar400.4 good amps. It will do 2x50 @4 ohms. If you don't wanna spend a lot, look on ebay for a jbl bp150.2.
