For that amount of power you need the biggest alternator you can get. DB Electrical and motor city reman make good ones.

I'd probably also do a 2nd battery with an isolator.

What kind of amp is producing this "4500rms"?

Your charging system will depend strictly on how efficient the amps is.

I would go with a the biggest alt for your car (why not? might want to upgrade again later) and also another battery in the back. Isolator is not required at all unless you want to separate the two batteries.
