  • Amp Startup

    Hi guys just wanted to know how to connect the remote switch from the amplifier my amp only has one wire for remote and the M1/M2-ATX

    the m2-atx amp-remote has both a 12v and ground line, just attach the +ve pin to the amplifier and that should be adequate. If you get some noise in the soundsystem then ground the other pin to the car body and that should get rid of the noise.

        Connect the left pin on the m2-atx remote to the remote on your amp, this should be fine.

          But its not much use.

          This remote connection will enable your poweramp much too soon. You will still get bumps when sound card is initialized.

            I use a USB powered/controlled relay. I have it setup to enable the amp at startup/restart and hibernate/resume. It works perfect every time.

              Something like that is what you need, Domino!

              I do the same thing as fabworks. Under software control (via COM) you can mute even if the PC is on too. Similar to fusionbox I guess.

              Well, if you can't reprogram the pic on the M2-ATX off-cause. There is source available to modify. But you still have to guess a delay time.

                AmpCTRL is another option, it runs as a service and uses pin 4 of a com port to switch the amp on once windows is loaded.

                  Yeah, I used AmpCTRL as well, but when my HDRadio took my serial port, I had to find another solution.

                  The usb powered relay is great and I have no clue why the current power supplies don't have this on them.

                    AMP control is the best hands down. It does require a serial port though. Check you mother board to see if you have extra COM PORT headers. My MoBo came with 2 external serial ports (XM and HD Radio) and then 2 internal ports (OBD2 scanner and AmpCtrl). i have 5 amps so the serial port was to weak to start them all, so I connected a PAC TR-4 to the serial port to amplify the signal.

                      Strange, I never have had a drama at all with the "POP" when using the remote on the m2 psu.

                      I have built a few carputers and these vary from mini-itx to usual desktops with builtin/external sound cards... Never had the pop in any of the setups when using remote.

                      Only have had it when having the amp remote wired direct to the 12v accessories.

                        It depends on the soundcard. Alot of USB cards suffer from the pop.... when I switched to the PCI X-Fi I no longer had the issues.
