i see some confusion in this thread... ill throw in my two cents.
First the OP, if I understand your post you have a steree 4x12, which can run in either 4/16ohms in mono or 8ohms per side in stereo. Your friend tell you to run from the 8ohm outs of your 5150 into the stereo 8 ohm inputs. That will cause an ohms mismatch as those two 8 ohm jacks are parallel. which will half both your 8 ohm inputs to a 4ohm load which is very bad.
high wattage tube amps (99%) cannot accept ohm mismatchs (up or down) without causing damage. You might be safe for a few minutes but your amp is going to lose mojo in the form of smoke eventually if play it too long that way.
Solidstate amps can generally accept higher loads then their optimal rating, but it will cost power. Generally assume if the amp wants a 4 ohm load, an 8 ohm load will half your power, and a 16 ohm load will cut 3/4 of the power. These is just a slight generalization as ever amp is different you can find the actual power dfferences in the manual generally.
and i just read the post above me.. which is pretty much spot on to what I just said
