find a used Adire audio shiva and stick it in a 1.5cf sealed box and give it 300w.... you could probably do all of that for 150-200 and you'll be MUCH happier... Find the shiva used (will be ~80), the box you'll have to build or find someone who will build it for you and the amp could be something like ohh (give me a sec)
I might actually have a shiva for sale.... if not they run ~100 shipped used and 150 shipped new... spend the small amount more for the better sub... it'll pound alot harder and sound alot better than that crap "system"....
