I'm having trouble with my infinity perfects whenever I turn the volume high they just keep cutting out. They just suddenly lose volume and turn on and off from the left speaker and then to right. And when I lower the volume they return to normal. it's just happening to these which are my fronts and nothing happens to my rears which are some pioneer 6x9 and I don't think it's a voltage drop because I'm running them on a jl audio he 600/4. Please help don't know what to do
