Based on your previous posts for the kit you are looking at, I doubt that any local dealer will come to your house for free or even do it for a fee.
They won't know you in terms of your previous purchasing history, and they would have to carefully pack into boxes a couple of pairs of speakers, amps, etc and bring them round to your house in a van. then they would have to unpack them. After the demo they would have to pack them again, and unpack them when they got back to the store. That's a lot of time and effort that you would have to pay for.
