I'm very satisfied with the sound of boxes, finally listen to music while driving. Unfortunately, the covers do not quite fit in place of the old covers therefore unfortunately have the old covers back on it and send the decorative covers gathering dust in the barn until I thought of something is what I can do with it. As anyone who wants incorporate them forward in a Chevrolet Matiz 2006 must be either creative or waive the coverage. The pit itself fit great and sound great.
