choosing the right amp?

okay i have a pair of

# frequency response: 49-21,000 Hz
# sensitivity: 92 dB

# impedance: 4 ohms

and my question is what would be a good amp to go with them? ive looked around and compared the higher end with the lower end brands and i came across

to me the specs look very decent, any critiques or advice on this? These go for about $100 and it packs the power i am looking for and if i were to go with jl or alpine i'd spend at least 2-300 for that power. Any feed back would be much appreciated!

specs or overinflated...take those ratings and cut them in half and there is your more realistic number
