    M2 ATX amp hookup

    Almost all the parts are in, I am looking at the power supply and setting up the wires. I noticed that I did not get a wire to connect the power supply to the amps. I see the hookup on the board. What do I use to connect the wire?

    You can find those kind of connectors at a PC parts store like tiger direct, maybe frys. I'd avoid major big box retailers since they won't likely have things like that at bestbuy or circuit. Go there and bring in your PS over there and they will tell you what to get.
    Or you can just solder a wire directly to that pin.

    Be warned, that some people, including myself, have experianced problems with that power supply pin amp turnon output. In my case I tested it and it appeared to not have enough current to turn on the amps, nor a simple relay (which only requires 200mA). They may have fixed this problem in later revisions, I dont know. Just be warned, that it may not function as stated.

    I control two amplifiers (Kicker ZX400.1 and Pioneer GM4300F) with the M2-ATX-HV's J6 connector (just the 'REM" pin, don't use the "GND" pin). been using it for months, no problems here. most amp turn-on leads draw less than 50mA so for most amps the J6 connector should be able to provide plenty of power for it. I use the "-HV" version of the M2-ATX so maybe it was an issue with the original versions?

    as for the connection, I soldered the wire directly onto the "REM" pin (I ran the wire to a 1/4A fuse, then to a I/O connector on the back of the PC case).

    if you don't want to solder, then there are a few connectors that should work. the J6 connector itself is the same as a 2-pin PC fan connector (these aren't used much anymore, most modern PC fans use 3-pin connectors). the pin spacing is pretty standard so there are a variety of PC connectors that you can use; any PC fan connector (2-pin, 3-pin, or 4-pin) should work, PC case header connectors, USB header connectors, Audio header connectors, floppy drive power connectors, etc. if you have any old PC parts lying around then chances are you have some old component that you can cut the connector off and use.

    good luck

    Fusion - Do you have any pictures that describe this setup?

    I understand what you did soldering to the REM pin (left pin according to the manual) ...

    But what does the I/) connector on the back of the PC case look like? Is that just a regular spade type of terminal that you then ran to your Amp Remote Turn ons?

    Thanks
