They are enclosures for speakers that go by your feet.

Kick panels that have provisions for speakers. $150 new. Here is a place that sells them: http://www.crutchfield.com/cgi-bin/S...=1&cc=01&avf=Y

Info:
Many award-winning sound-off competitors put their mid-woofers and tweeters in custom-built kick panel enclosures because that's one of the best ways to get a concert-quality stereo image. But why pay hundreds of dollars to an installer? Mount your 5-1/4" components in Q-Logic's Q-Forms, which deliver competition-quality imaging without the expensive custom installation work.

With Q-Forms, each speaker is located and angled to maximize sound quality. The theory is that the distance between your ears and each of the speakers should be equal. With your speakers in the kick panels, it's like sitting in that "sweet spot" at a concert or right between your home speakers.

You can mount a tweeter with a maximum diameter of 2-1/2" and a midrange/midbass with a diameter size ranging from 3 1/2" to 5 1/4". The maximum frame width/diameter allowable for the midrange/bass driver is 5.9", so a few 6-1/2" units may fit. Our database contains information relating to cutout requirements, frame width, and mounting depth of all of our speakers, so please check with a Crutchfield sales advisor before ordering if you wish to use 6-1/2" speakers in these kick panels.
