question where to get cheap 1500 watt amp for ka-6100

Solution
The speaker set up can't actually handle anything like that. The problem you are going to have is that surround sound receivers do not have amplified subwoofer outputs and the sub in that system is not self powered so you will need to get a receiver and additional amp. I would suggest that given the price and low quality of the Kinetic KA-6100 and the cost of buying the additional components to get it to work you would be better off buying a home theater in a box which will include these components.
