I've ran a 50x4 head and 4x Pioneer 6x8 3-ways in my truck for over 2 years now, and they're still as good now as the day they went in. I don't have the specs on the speakers anymore, but they were rated somewhere in the 2_ _ watt range. I've never heard of anyone cooking a speaker from being "underpowered". Wire 'em in and enjoy it. They're great.
