how are people moaning about this when there are like $5 kids toys being sold for like $200!! Some people just cant be assed to buy all the seperate components then figure out how to connect them up. Your paying for the time / effort to create the kit / support if you need help installing, not just the raw components. Prices looked fine, no one is getting rich.
I'm sure some one will create a 'poor man's pinwoofer' thread soon lol
