Better power to those infinities may get you where you need. I had a set of reference components and they were very bright, even when off axis. Did you set the crossover network to the higher setting for the tweeters? Many crossover networks have a way to tune your tweeters a little louder or softer.

To get your subwoofers to put out more sound you will want them in a properly sized and tuned ported box like Danometal said, and positioned in your car for the greatest output. They will also need their own amplifier. Sometimes folks have subwoofers firing foreward and up against the back seat, when they might get more output if they face backwards there as the soundwaves that reflect from the rear of the car can be more in sync with the orignial soundwaves and you get more output. Sometimes the you can get more output if they are as far back as they can be, but facing forewared as well. I don't know enough about your car to give you the best recommendation, but it's something to consider.
