I love the sound of my Carvin 2x10, with Emminence Kappa speakers. I've had it for a few months now. It holds up at the local bars and did its job on tour. But I've got 2 speakers that handle a total of 800 watts, and I've got the measly little stock crossover installed. Does anyone know of an upgrade that can handle all the power the speakers are capable of? Or at least something close?
