Couldn't tell any sound difference between these and the original Chinese speakers in my K1500. The good part about the originals is they lasted many years while one of the Pyles failed in a couple of months. I had low expectations that anything resembling good sound could come out of a 4 x 6 speaker. At least it didn't cost much to find out I was right.
