The obvious thing to mention is that your mix is indeed going to sound different on different systems, and those people are going to judge that by reference of how 'other stuff sounds on that system'.
It comes down to the old saying; learn to know your monitors.

Listen to well done professional CD's on your system (at low volume) during breaks .. and let your ears adjust to that sound.
Then get your mix to sound like that 'on that system'.

Of course it will sound different on different systems. That's the reference part of monitors. That's where you start. You can't compare a boombox to a car to a home stereo. The idea is to learn how to make the mix representative on all systems, and that starts with knowing your own.
I'd like to get a little better treatment in my home mixing room, and I may remodel it this winter, but I've spent time learning the monitors and the room. Both matter. Not saying you need the absolute best of both, just that you need to learn the ones you have and get to where you can trust them.
