How would I run the remote-on wire from the Alpine H701 processor to multiple Alpine PDX amps (2.150 and 1.600)? The H701 has one remote-on wire....would I need a relay like this?

I don't want to use something like this unless absolutely necessary.

 

you should be able to just use the one wire for both amps. just run one remote turn on wire to the amps and then split at the amps

 

yeah second that. Just jump the remote wire terminals from each amp and connect one to the remote wire out of the deck. Or you could split the wire at some point for a cleaner look, but it really doesn't matter.
