does the amps have a rca line output? if so, chain the rca's from one amp to another and the bass knob goes into the first amp, that way it controlls the bass going to both amps

what are your ohm subs do you have?

did you not recieve the instruction manual?

it will tell you the lowest ohm load for the channels

also you can take neg from (amp 1 )speaker terminal to neg of (amp 2 )speaker teminal and pos of amp 1 terminal to sub pos and pos of amp 2 teminal to sub neg if you go this way then leave the subs parallel for 2ohm load then wire in series to amp for a 4ohm load for two subs

amp1 would be your master amp 2 would be slave

Ah, no, you cannot do that with most amps.
