2nd that these are fantastic as well as using Audio Uprising for the fronts. Great pairing with the AlpineKicker KS series is also a good budget option. Silk tweeters sound better to me and are less fatiguing. For the soundbar specifically there are options that can add 6.5" or 6x9" speakers without cutting up the factory bar. At least I am sure about the 6.5", the 6x9 might still need alterations.
