  • m2-atx & 2 amp remote connections?

    I tried searching but couldn't find anything.

    How could you connect the m2-atx to 2 amps. Can i split the wire to both of them or will the current be insufficient??

    I could be wrong, but the current on the remote wire is going to be minimal anyway..it's not the current you're worried about. It's the voltage drop, and Unless your run is really long, again, I can't imagine that being an issue either.

    So yes, split the wire in 2.

    It might be easier to go from the m2-atx to your first amp, and from your first amp to your second...instead of 2 wires going from the m2-atx to both amps...just something to consider.

      I have the same problem. I tried to connect with the same wire the two amplifiers but nothing happened. I think that might be a voltage drop.

        you could always use a spdt relay to send a +12v remote signal to your amps

          I had in mind to make my self a relay suppling 12 V but how i can make the delay.Sorry what means "spdt". Whre I can find something like this.
          Thanks in advance

            Single-Pole, Double-Throw... it's a switch layout.

              You can just run the remote wire form one amp to the other amp. Works fine for me and never had a problem with it.

                doesn't that cause a voltage drop, or do amps accept a wide range of voltages for remote input?

                  To my knowledge, it probably does create a voltage drop but then again the remote wire connection on subs and almost every other car audio device only needs a 5 volt signal. I think that they do accept a wide range of voltages.

                    the remote/ignition wire on the Amps... are just there to trigger a relay inside the amps anyway...

                    you will be fine running the remote amp lead from the M2-atx to the 1st amp and from there to the 2nd amp...

                    thats what I do.. except I have a Carnetix..

                      Without load the J6 of M2-ATX has 12 V output.But when you connect a relay there is a Volt dropage and the final output is 5-6 V
                      There is not efficienty power even to trigger a 12 V relay

                        RL - 12V (Relay)

                        So now the M2-ATX can trigger with low voltage the relay to power the Remote cables
