question

i have a question for you guys who know their $hit about sound systems. Take a look at these specs for a 10 inch Kicker impulse subwoofer... and maybe tell me if 2 of them are worth 120$ bucks.

Single woofer
Impedance: 4,8 Ohms
Maximum Amplifier Power: 125 Watts
Sensitivity: 89 dB 1w/1m
Frequency Response: 30-1000Hz
Mounting Depth: 4-1/2", 114mm

Minimum Recommended Sealed Enclosure Volume(cu.ft,l): 0.8, 22.6
Maximum Recommended Sealed Enclosure Volume(cu.ft,l): 1.2, 34.0

i will also be getting a 200watt amp that runs on 4ohms? or something like that... can someone please tell me if any of this sounds any good. because i dont want to get ripped off
