Ok, so I got a brain fart guys.... If I have a 4 channel amp, and want to bridge to 1 single sub..... Can someone guide me in the wiring?? On the amp I had b4.. I was using a 2 channel(zr360) amp bridged. I used the rca out L/R and L+ and R- speaker input on the amp to the sub...

To my knowledge you can't bridge 4 channels to 1 sub output, unless the amp is specifically set up for that. If your amp has dual voice coils, you can bridge each PAIR of channels to make 2 outputs, then drive each of the sub's voice coils. Check your amp's manual for the proper way to bridge it - usually you need to throw a switch in the other direction and use two specific output terminals.
