You didn't "bridge" the subs. You wired them in parallel.

What kind of amp do you have? What kind of subs? Are they SVC or DVC? How many ohms?

Not sure why they quit working because of a simple wire change, but you need to give the details of exactly what you have.

SVC = Single Voice Coil
DVC = Dual Voice Coils

You're using a 4-channel amp? Are you just using a single channel on your subs? You said you ran wires from the amp to one sub, then wires from that sub to another sub. I'm a little confused as to what you're doing.

My guess would be that amp isn't stable at 2 ohms bridged. You have two channels bridged and you have two 4 ohm subs wired in parallel which gives you a 2 ohm load. Check the specs on your amp to see if it's supposed to be stable bridged with a 2 ohm load.
