I just got in my new amp and hooked it up to my 2 as yet untested Bose Panaray 402 Series II speakers and got no output at all. The amp is connected to the speakers with 2x 50' speakon cables and i know the amp is getting good inputs because I am seeing deflection on the output LED's. I am worried that they are either dramatically underpowered, or not working at all, the speakers are a little old, but I am not even hearing buzzing or crackles. The amp is 2100 W peak but pretty cheap, brand new however. Whats the problem here?
