would my head blow this cab?

[crimson on pink]

so i'm gonna respeaker my 2x15 and wanna make sure i'm not gonna blow the speakers in it. i've settled on weber thames, which are 80 watts a piece. i'm gonna be running a sunn coliseum pa thru it(4xkt88's). run the volume on that anywhere between 7 n 9 on it. play stuff along the lines of torche and baroness. would i blow the cab? would it better if i ran two cabs w it to not stress just the 2x15? thanks!
