I would PM Jon from SS he was a huge help to me and almost immediately told me what I needed to do to get the best sound out of my car. Best part is he broke down why I needed each product he quoted me for, how much to apply and where it needed to go. I am going to be running SS simply because of customer service like that, it seems uncommon nowadays to get a rep that gives a damn about your car and isn't just trying to sell you the most expensive stuff.
