Great speaker

The following review is for K 170, which is a part of the bundle you are viewing.

You can tell that this is a high-quality product. The highs are clean and clear. The mid-range is very clear. I replaced the rear door factory speakers in my 2015 Sierra it made a huge difference. It was what I expected and thought I would get from a Hertz product. I am not sure about the durability. Features make sure you have speaker wire other than the tweeters you will need some.
