I'll break this down into several categories. Device: Works well. The box is smaller than I thought. I have no doubts that this will take a while. I'm glad I spent the money on a prettier box rather than a non-shimmery or solid color. Installation: Depending on your vehicle, removing the headliner may take 25 minutes or 2-5 hours. Expect to break numerous clips. Once the liner is taken out, everything else becomes a tedious job. The real fun starts when you try to lay the lines. If you are not organized. The shit will hit the fan, and fast! I highly recommend using 14ft instead of 9ft. I ran about 2 feet less on the G35 coupe than I originally intended to put in the pits. In the end it went well, but the box couldn't be hidden.
