I'm running one front and back, over the transducers Pete.
I asked a 'lectronics dealer, he didn't know, so he said he called H'bird
and they said it couldn't be done :p Don't really know who he talked to.
I went ahead and tried it anyway, and it works fine
I'm using an "AS-Y" cable on each unit to hook up the puck, the socket
on the interlink box that is for a puck, is left empty. Holler at me if that
don't make sense.
