No Noise from Pioneer HU

[Burke 1]

Long story short, my system has been under construction for quite some time. I decided to throw some speakers in the doors via the factory speaker wires just to have something to listen to, but there was no sound. My first thought was a short somewhere in the wires, so I wired one speaker directly to the HU's harness (literally at the back of the HU, not through harness adapter) and it still produced absolutely nothing. I played around with the settings and couldn't find anything that could cause this. Am I missing something stupid, or is this HU fried?

What model pioneer?

Some models have the option of turning the internal amp on/Off...no output if turned off
