is there an easy way to connect two amp speakers together in series without having to cut the 1/4" jacks off and wire them by hand? is there some sort of adapter that will do this? i just got a great deal on a power attenuator, and this is the only way to make it work...but i can't seem to find anything that exists for such a purpose.

it needs to have dual input plugs for each speaker jack, and a single output to plug into the power attenuator. and before anyone suggests it - i can't make one myself and don't know anyone local that can either. i've been calling around all day for this. :) i need to match the ohm ratings for the power attenuator.

it seems so simple, but is proving quite difficult...

thanks!
