Vibrations will definitely be in the back of my mind as they were while I was doing the install, but the box is double baffled. You can feel vibrations when you touch the box, but honestly, I think the seats vibrate more. I do appreciate the tips/concern though. Also, there will definitely be more mods in the future. I'm looking at a BB with shocks to get a little lift on it. I'll probably go the extra half inch and get some 31s at that point too. I have 245/75R16 tires now which are 30.46 inch tires. Hopefully I'll have this by the end of summer. As far as the tweeters go, that wasn't my idea so I'm no going to take the credit for that. My friend thought of it as I was looking for some 1/4" MDF to cut up to use for them. His way was much faster and I'm sure it looks infinitely better than any wood adapter would look, although you'd probably never see them anyways.
