Decent Speakers

These were good at first when I got them, I had about 30 Watts RMS going to them from a Soundstorm 4 Channel amp. I had 2 sets in the back back of my explorer (custom) and they were goin strong, but then one speaker blew. Now that was my fault. One day when I was testing them out, I accidentally switched them off of high pass to low pass and the bass blew out one of them. I really like these speakers, but just watch your settings and bass. And I'm also not sure if I'd put 60 Watts RMS to each one. Maybe 40 tops?
