It does sound like you're cross-wired. But to make sure you aren't confused, I'd try to grab a wiring diagram to be sure. Trace all the wires to make sure you know what speaker wire is what, and then start from scratch using your wiring diagram.Before you start running wires, you might connect each speaker one-by-one to a known good output to verify that each speaker is functional. Might check each amplifier output the same way. Then you'll know that everything is working, and you can focus on making sure you connect everything up right and don't get your wires crossed.
