wiring subs to amp

i have to 10" subs and a 2 channel amp.  the enclosure has two plugs on each side of the subwoofers.  do i run a positive and negative from each subwoofer or can i bridge the wires to the amp from one plug?  will that make both speakers play?

if the subs are 4ohm run them to each separate channel, if they are 8 ohm, you should bridge them.  Or if your amp can handle 2ohms, then you can bridge the 4 ohm subs too depending on how much power the subs can handle and how much the amp is going to put out
