Yeah, I did. I went through about 6 or 7 cutting wheels with the Dremel... I started by making a template out of hardboard (like pegboard with no holes), then cutting that shape from plexi with a jigsaw. I took the sub, put it over the rectangular holes in the panel, traced it with a Sharpie, and then cut out that circle with the Dremel. Then I mounted the sub to the plexi with machine screws and attached that whole assembly to the car with self-tapping screws. A few spots, you'll have to flatten out the sheet metal with a pair of pliers or vice-grips so the self-tapping screws will reach, but overall, it wasn't that difficult. If you're interested, paypal me 10 bucks and I can send you a template. Oh, also, you have to cut off a little corner of the bracket that's directly underneath. I think you can see it in the pic.phuphyter wrote:More details would be nice. So did you end up grinding?
