Easiest way to upgrade my Harmon Kardon system

I just purchased subs for my car but I'm worried the stock Harmon Kardon system won't be loud enough to keep up with bass, I was told factory amp is pushing 40 watts per channel, should I get bigger amp or upgrade speakers or both?

You can upgrade all the system if you wish, or get just an amp for the subs.
What kind of subs did you get?
