Do you really plan to run around town with your system playing full tilt sine waves? Music is dynamic and estimating current draw will not really get you the answer you are looking for. A better question to pose would be to outline what other gear you have, how large your alternator currently is and ask what you should do to reinforce your electrical system to support it.
