The best way to do it would be to use your amp remote to trigger a relay, then use the output of the relay to turn the amps on.
search on
www.bcae1.com to see how they use a relay to control fans for amplifiers - essentially the same applicaiton - just make sure you fuse it all properly.
I don't see how this could happen because the voltage is of such a low current when coming from the head unit, it's simply something to tell the amp to turn on. They way I do it is to have one wire come back from the HU and then have all the other remote wires from the amp to connect to this one wire from the HU.
