The manual is on crutchfield and the back of the box the speakers come in. I realize you probably have them hooked up since this is 5 months old but if anyone searching is wondering the proper input is 1+2 for the SPX-17ref if you're not bi amping. Also there should be 2 jumpers in the middle (to the right of #4 in ur pic) Looks like you have them in there.
