Can you use a 4 channel amp to run 2 channel stereo?

I have have jl audio 300/4 as the title suggests can i run a set of jl xr650 csi off them using the bridged mode in stereo? How would the rca leads work? because it has input for front and back? How do i adjust both gains to the same value?

Should be able to just use one pair of RCA ins. And yes, you can bridge it, just be sure not to overpower your speakers. Just eyeball the gains to be around the same - actually, technically, they don't need to be anywhere NEAR the same -- but why not?
