I've got one in my daily driver SAAB, but I don't think it would work for anything save a late-model soundproofed Rover Mini. It lowers the bottom end of your speakers' range, but certainly doesn't add any oomph to the sound. As said elsewhere, for a loud car like a mini, you're going to need more sub size and more power to make audible bass happen..
