Subwoofer would be an option and not hard to add, but cost would double on parts ($200=$400 or more with sub and box).

I highly recommend if you do not want to upgrade to a new head unit to at least use a LOC or a mtx re-q5 and add new amps to power your new speakers as they are going to want more power.
