What can I do to fit a 3-way component set in my Grand Am, plus some?

I'm going to put a JBL C608GTI MKII component set, an A/D/S 344is midrange driver, and some 1" tweeters in my 2002 Pontiac Grand SE. I know I can put the 6.5" woofers in my doors and I already have a stock place in my doors for one set of tweeters. I've heard of Q-forms and pods, but what else is there and what are the different kinds? I don't want to do anything with fiberglass or building custom door panels. Customizing yes, custom no.
