For the subs, I would get the MTX, simply because they are just all-around better.
For the amp, I would not get the Bazooka since they are rated higher than they really are. I do not know much about the Sony amps but I know several people on this boad do not like them. I have a Kenwood amp and have never had a problem with it, so I would recommend the Kenwood amp.
I am just going by brand names and what I know of them, not any specs since I have not looked them up - you happen to know the specs of the amps?
