2 amps-1 remote wire

[talleyjamkc]

I have an loc spliced off the rear speaker wires going to my sub amp and now i am going to add a 4 channel loc to the main speaker wires to amp my doors. will i need to run 2 remote wires from the ignition (switched) wire to the amp turn ons or can i splice the blue wire in the name of laziness? and if i share the one blue wire, should i install an in-line fuse? think about that one.....
thanks

The turn on signal is just a signal and the amps draws next to nothing from it, same principle as a relay really. You should be fine. Since this is a Mazda spesific system I would find a multimeter and check the voltage first though, it just might be ground switched instead of positive switched.

The remote turn on singal usually comes from the cd-player not the ignition btw.

You will be fine to jump your remote wire from one amp to the other. I have daisy chained 2 amps before with no issues. If you start getting too many amps in a row, you will eventually have issues, but two should be fine.
