The sub is alright, but the amp is junk. only 32watts x 2 channels. 100w(rms) if bridged. and the sub is a 10" kicker, 300 watt max 150 watt rms, the amp won't push the sub to it's full potential.
I would buy that setup and just sell the amp and get a new amp. thats a good price for all of that, the sub retails around $60 the amp is around $100, The box I don't know probably over $100.
