Just built a rack with a CS800S with the S1 module installed from Craigslist. First time dealing with this kind of setup. I have it going into 2 4x10 cabs but it's not anywhere near the loudness it should be. I know I don't have it hooked up correctly and have not found any info that really makes sense to me. Just curious what cords I need and where they go to get the max out of this amp. I've included a pic of the back of the amp.
