my amps were Rockford Fosgates ( . . ) I think it has something to do with the way the system grounds. So I bought some new amps that worked with the empeg

Funny, I use a Rockford Fosgate too, to satisfaction. Initially I had some whine, but that was killed by connecting one of the ground leads to the Empeg player (!). Since then, no whine, good sound (but loud pops on turning off ignition - possibly caused by Rockford's MOSFET design that are said to be more sensitive to current discharge)
