mach 460 problems

[roxanne@'95 gt]

does anyone know where i can download a wiring diagram or schematic for the mach 460 system in a '95 gt? i am trying to install a clarion dxz845mc head unit while retaining the mach amps and speakers, using a schoche premium sound system plug-in harness. at this point, we have power to and operation of the head unit, and it sounds as if the amps "pop" on, but there is nothing from the speakers, and i'm lost as to what connections i'm overlooking or what may be wrong or missing. i've punched every mach reference i can come up with into "search" and cannot come up with a wiring diagram or possible solution to what's wrong. all the help i can get would be greatly appreciated. thanks
