_{You wired it up wrong.}

I bet its out of phase... Makes most sense.

i dont see how i could have wired it up wrong its pretty simple. and i dont think they are out of phase cuz it works on one amp and not the other with exaxtly the same wiring

Sounds like it might be a bad amp.

seems like it .

I have heard of a batch of BC2000K's that had output issues, IE, was a small batch that was bad from the factory.

I would contact Crescendo and find out if your was one of them first.

ok thanks ill check with them.

Didn't those have a input switch for voltage from the rca cables.

I was incorrect on that mistakin for master slave switch
