Wiring a subwoofer to monoblocks


Just picked up a REL Quake
REL's manual speaks about differential amps – does this mean
Mono blocks?
No friggin idea how to wire it up.
My i/c’s are fibre optics which break the ground between boxes so wiring the earth to the pre is no use.
To make matters worse, the Audiopax reverse polarity /phase.
Have mailed REL but no reply.

When the manual speaks about wiring to the chassis ground,
How do I check this?

Next problem will be a plan to use two subs and I'm not any clearer from their manual how this will be achieved.

I have spare pre outs on the Supratek but would prefer to run the the sub/s using the hi level inputs.

When I had a Rel for the front I connected the Left and right to their terminals, then I connected the common to the preamp. When I tried it to one of the amps I got a loud hum and did not when I connected to the ground tempinal on the preamp.
