Personally, this is how I would wire everything up. I would use the remote wire into the amps, as the trigger wire for the relay for the fans. Connect the remote wire to the amp, then branch off another wire, from that remote wire, to 85 of the relay. Ground 86. Run another constant 12V wire either from the amp, or from your distribution block to 30 of the relay. And run a wire from 87 to the positive wire of the fan. Ground the other wire of the fan.   That will take care of the fans turning on and off with the amps. To power the crossover, I would suggest that you take another 12V wire off the amp, or the distribution block to the 12V of the crossover. Again branch off a wire from the remote wire into the amp and run it to the remote of the crossover. Then ground the crossover.

That should take care of all the connections that are to be made.

thanks for the advice.i never thought of running the remote from one amp to the other.so when i wire the remote wire for the first amp i can just take another remote wire and add it to the same screw as the first remote wire and attach it to the next amp?then repeat that for the third amp?I hope that made sense.thanks again
