If the object of the exercise is to make the track louder, then probably the easiest effect to use is “soft clipping”.
What this effect does is to “squash” peaks that are above the threshold level that you set, and so allow more room for amplification. It differs from the bad digital clipping that DVDdoug described in as far as it does not completely chop off the peaks flat, but just squashes them so that they are not as high, though if you use it too severely, then you will hear distortion, so the trick is to use it enough to provide the necessary volume boost, but not so much as to sound distorted.
