My parents have an 06 X Star with Zapco Amps Powering the system The problem is that when the system was installed they set up the system with the subs on a Zapco DC1100.1 and the tower speakers and interior speakers on a Zapco DC1000.4.
Right now there is one symbilink cable going from the head unit to the DC1100.1 and another from the head unit to the DC1000.4 into the 1,2ch input. and the 3,4ch input is not being used. From what i can tell the interior speakers are running off channels 1&2 and the tower speakers are running off of cahnnels 3 and 4.
What we want to be able to do is fade beween the tower speakers and the interior speakers.
The problem that i'm having is when I hook up the 2nd symbilink to the 3,4ch input on the DC1000.4 I am still not able to fade the tower speakers. I tried fading through the head unit and with a clarion EQS 746. What happens is when you fade one way nothing happens and when you fade the other way the entire system turns down. So it's like all the speakers are on the Front channel or all the speakers are on the rear channel. What i want is the tower speakers on one channel and the in boat speakers on the other.
What do i need to do to get the amp to recognize the second Symbilink cable on the 3rd and 4th channel? These amps are a little beyond my undersatanding and any help would be greatly appreciated.
