Adding a monitor to spider jam speaker

I am wanting to add a peavey Impulse II monitor speaker(16 ohms) to my existing 8 ohm speaker on my Spider Jam V, 75W.  The total resistance of the speakers will be reduced from 8 ohms to 5.333 ohms:  5.333=(8)(16)/(8+16) A parallel connection connecting negative to negative and positive to positive speaker connections.

 

P=I*I*R

P=75 Watts, R=8 Ohms, I=3.06 Amps

or

P=75 Watts, R=5.333 Ohms, I=3.75 Amps

 

*I am not sure the above calculations are correct.

 

Will my amp be healthy and not fry or overheat from the additional amperage?

 

I sing and play acoustic allot and I would like to monitor myself singing and playing but place the Spider Jam Amp in front of me , far enough away so my guitar and microphone will not pick up feedback. I am using the Spider Jam as the PA.

 

I already changed out the Spider Jam's speaker with a Eminence Maverick speaker and am delighted with the fuller sound and versatility of the Maverick's adjustable inner magnet core.

 

Any advice would be helpful and thanks,
