Those are just the basics...once you start getting a little advance then you need to gain match each driver, add Time alignment, etc which would warrant a new deck...
I would say start very low and carefully work your way up. Keep an eye on the mids excursion especially and high pass it no lower than 80hz to start with...
Be careful with the tweet unless you can find out what the FS is...personally I would go no lower than 3500hz with the amount of power you have to work with...just experiment...
