I haven't installed car audio in about 20 years. So naturally I was little wOrried abot tearing into my brand new car. It took me about 7 hours to install. I broke a few pieces of trim, although nothing serious. I scratched my door sill removing the drivers seat and lastly I cross threaded a seat bolt but just need a new bolt.
But in the end.. It was great experience and the damage was minimal. Only issue now is the amp is mounted under the seat and it is impossible to adjust the amp without removing seat.
