I have 2 10’s that are 2 x 4ohm stable. I’m running a cheap 500wx2ch legacy amp. “model la770”.  
Sub’s are bazooka 10’s dual-voice coil.

What is the best way to run a 2 channel amp into 4 channel inputs of the subs?

Buy a better 2 channel amp and follow the diagram dreid posted, or buy a 1 ohm stable monoblock amp and wire all 4 coils parallel to eachother.

I wouldnt suggest using a 4 channel. Most 4 channels dont offer low pass crossovers for all 4 channels, its usually low pass on just channel 3 and 4.
