To hook up a 4-bulb vanity light to the wires in the wall, what is the best way to twist the 4 wires (4 black, 4 white)together and to the wires from the box? The box is very shallow and when I tried to hang it up the marets needed to be pushed aside so much for the bolts to come through, one or more of the light's wires slip out of the maret...
Do you have advise?

Try small wire nuts (marets). Sounds like the ones your are using are too large and are not properly securing the wires.

What gauge wire are you using and which size wire nut? They are rated on the bag or box as to what they will handle.
