What kind of subs do you have? How many voice coils and what OHM are they?

In my experience, a mono block with 2 sets of channels will bridge the two sets internally.

connect all the (+)s to the amp and all the (-)s to the amp, that should give you a 2ohm load, provided that each sub is svc 4ohm

I know that some amps will internally bridge the speakers together in parallel. You could either plug one in to each output or wire them in paralle and use just one set of outputs. It would end up being the same. The older jbl bp amps were like that. Go to the rf website and look for a manual just to make sure. If you cant find it just call their tech and they should be able to tell you.

well the book shows that if you have 2 4 ohm subs wire them seperately and if you have one 2 ohm sub wire it to the first channel so i wired the subs seperately

Yeah so it sounds like both the terminals are in parallel. Either way will work the same. Both ways will present a 2 ohm load to the amp.
