if you blew any of the speakers, it's due to one of two reasons: your amplifier gains were set too high or you lack a sufficient charging system to handle the current draw of the amplifier(s)
end result is the same: amplifier clipped and destroyed the speakers.
you did check things like your ground connection already I'm guessing anyway the amp is probably blown, but you should find some time to go get it replaced by the place that installed it it should be under warranty
