Specs should be on the amp itself. As far as I know, 5 channel amps have the 5th channel as dedicated sub channel. The Manuel should say what ohm the channel run at and at how many watts. Bridging or running parallel will give different ohm (like use 1 + terminal from on channel and 1 -from another to run a speaker vs combining 2 +wires together and 2-wires together to power a speaker).
