Hello smart driver, I just wanted to tell you that the soundparkete that smart offers nothing is good for all garbage. I bought a smart to my 18th a facelift bj 2005. a nice car. I thought I would get the original subwoofer and the tweeters. well, by chance, one of them had also in the city of the part and it’s not ́s then I also need to spend net so much money. I drove to the acr man and got advice and it came up with a result of 131,8 decibel out. what can be seen for a smart. so finger away from the original smart kram.
