    well mine gave me -11.98 before the service started then 11.98 when it turned on but thats on my atx mobo and it turns my amp on perfectly connected directly to pin 4 so i think only way your gonna tell is if you hook your amp up and see if it turns it on. may be a problem if your just getting 9 and ur amp needs 12v remote on?

    I thought you were supposed to use pins 4 & 7 when measuring voltage - maybe it doesn't matter if it's 7 or 5? I got 12V on my Thinkpad T30.

    Most power supply I have seen here have a RMT pin, which is used for powering the amp. Wouldn't it be better and just easier to hook it up to that pin?

    Some installs have electrical noise or thumps while powering up the computer. Using the remote turn-on lead of the PSU powers up the amp when the ignition is turned giving this noise a chance to be heard. Turning on the amp after Windows has started will eliminate this noise. There are other ways to turn on the amp later in the power-up cycle like using a delay switch. Personally, if DTR works like I expect, I prefer it over a delay switch because it will be more precise about turning on the amp at the right time after Windows is booted.

    I was thinking I would just write some code to turn the volume down, kind of like a good home stereo will do when it's powered off. That way if I get out of the car with the vol up high, when I go to leave for work at 6am I don't wake everyone up
