Conclusion: I installed these into my 4x10 speaker holes in the front of my Pontiac Fiero. These speakers were wonderful for about 2 weeks. Then the right speaker started shorting out causing a crackling noise at even the lowest volume. Then a week after that the left one did the same. I have a feeling these are very cheaply made speakers and I will probably not purchase or recommend Boss audio products again. They now lay in the trash.
