Thanks, Zd. The pin idea is a good one and I had already tried to find pin connectors that would accommodate 10 gauge wire locally (Radio Shack) with no luck. I will do as you suggest as soon as I locate pins that will but, in the meantime, I'm using a 4 way speaker selector with banana connectors backwards (using the speakers out for the amps and vice versa. It works but my concern is that it is possible with this setup to engage both amps at the same time unlike the DPS-1 which allows only one at a time. I don't know what the result of this happening would be but have to believe that it's potentially a bad thing.
