No, I do al the work on my car myself, I don't let anyone touch it. I used GTmat, they are a great discount alternative to dynamat, and they are offering free samples here online. Check out their thread in this section, it's great stuff and easy to install. I would like to eventually go to an alpine pdx-5 or V9 amp to run my components as well, but my setup sounds great the way it is so I'm not stressing it right now. As was me ruined before, we don't have much cubic space in the cabin so you don't need the same amount of power or speakers as in, say, an suv
