Yup, done those things on the HU. I was wondering if a 3 or 2 way speakers to pick?

First decide if you want a component type or coaxial type set of speakers. If your stock speakers are two-way type components then it is advisable to replace them with the same type (2way components). By the way I am referring to your Front speakers.
As for the rear better to get 3way coaxial type speakers.
