I think it was about 4 months after I bought my car when I installed my head unit to replace the 0w single-din empty airspace the car came with. I promptly blew the 15w rated 8ohm stock speakers to the point where only one made noise, so I stopped listening to the radio. I just recently replaced the speakers with CDT CL-61a's and an Avionixx 400.2, which at least play music loud enough to hear over my open o2 housing.
