    M2-ATX connection questions!

    I just recieved my M2-ATX in the mail. Seems to be a very sturdy card. Im kind of confused on how to connect certain things....

    I know that Positive and Negative come directly from the battery, but were do I connect the switch wire to. Do I connect it to the cars radio Ignition wire, or do I have to run a new one from some place else?

    I see that there is a connector for controlling the amplifier..... how does this work? I have 2 150W amps.... one for front and one for back. Both are run directly from the battery and grounded to the chassis for ground. The amps have the third wire for remote on. Do I simply run the remote port from the M2 to the remote wire for the amps? According to the instructions, the J6 ports left pin is for remote and the right pin for ground. What do I connect the ground on the M2 to?

    Also what jumper settings to you recommend? I used Mode 3 / 5sec - Never
    Is this an ok setting? If not what do you recommend.

    Thanx in advance!

    That would work. A cigarette lighter is another good option in most vehicles.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Ok, i figured it all out, all it took was alittle research..... Everything, including the amps, and pc should come from the main positive battery post. The negative goes onto the chassis of the car, preferably the manufactures ground points.

    Also what jumper setting do I use..... ? Is mode 3 ok?

    Last question...... What guage wire should I use? I would like to connect everything, like amps and PC to one heavy duty wire. If the wire is to thick, can it have any type of bad effect? What I was thinking is having a heavy wire coming from the main battery into the cabin to a little junction box were everything will connect from there. Also same with Neg, have a junction box then a heavy neg wire connect to the chassis.

    As stated before the car has the car pc and 2 150watt amps which will connect to this main cable.... I will also be adding a 600W amp. Should I run another heavy cable or can I connect it to the same one I plan to run?

    Maybe something like this I can use? http://cgi.ebay.com/NEW-1600W-4-GAUG...QQcmdZViewItemIt supports 1600watts. The amp will only take up 600watts and the car pc i think is 160watts, and the 2 amps total 300watts

    Im sorry if my questions are kind of stupid, but I do not want some type of fire or explosion like the toaster picture.

    You are learning, young padawan.

    That's all a matter of preference, I'd think.

    Two words: distribution block
    One thicker (lower guage) wire goes in, several smaller (higher guage) wires come out to your devices.
    I recommend a fused distribution block, that way you have fuses on the power lines that run to each of your devices, adding another layer of protection in case of a short.

    Dude, a few months ago, I was asking these same questions. I feel your pain.
    Nobody wants to be the subject of the Toaster Picture.

    In order to do wire this all up CORRECTLY, you need to figure the amperage of all the devices. That's two 2ch amps, the sub amp and the PC. You get a single cable that can carry that load over the distance of your cable run. If it's close to the limit of a guage, go with the lower guage (thicker cable) for safety's sake. Use the same guage for your ground. You can get an amp wiring kit in just about any guage.
    My setup uses 4awg for main power for two modest amps, the PC and an inverter, over a run of about 12 feet (I've never actually measured it).

    Use a thinner wire that's capable of carrying the load for each device connected to it coming out of the distro block. In mist installations, this run will be much shorter, so if you're close to the limit of a guage of wire, you should be fine. You could go thicker if that increases your comfort level.
    I have 10awg running to each of my amps for all of 1-2.5 feet. I have 12awg from the distro block to the inverter & the PC.

    It's a lot to figure out, but once you do, you can be assured that your system will be safe, and we'll never laugh at you as you toast marshmallows over your car on the side of the freeway.
