Tells you on the spec page for the amp.

@ 4 Ω   70 W RMS x 4
@ 2 Ω   90 W RMS x 4
Bridged @ 4Ω   180 W RMS x 2

where it says bridged @ 4 ohmns 180w rms x2  that is where I will be running the sub of that channel bridged so will it be more than 180w as its only a sub and not 2 x speakers

you have 4 channels. bridging 2 of those channels for a sub at 4ohm will give you 180wrms. the other 2...your going to run your front components off.
