okay i am running a compaq laptop with an external soundblaster card, i have the amp powered to turn on with the ignition. I also have a power switch wired up for the laptop so i can turn it on and off whenever i want, i tried turning on the laptop first then the car and the car first then the laptop, i still get the thump. From my searching on here i understand that to be the sound card getting turned on after windows has loaded, now can i put the soundcard program into the start menu to get it to turn on? Otherwise i think im going to have to wire up another switch and turn the amps on after windows has completely loaded.
