2. Use the amp turn on wire off of your power supply. Almost all power supplies have this wire comming out of it. They are usually set to a small delay that will prevent turn on pops.

yup...

welcome back dubs. how was the honeymoon?

Didn't realize you where using a laptop. But you could wiring the power button to the dc-dc and probably the power too depends on the power requirment for the laptop.

just wire off the the acc line and put a delay on it to avoid the pop.

Its a ibm 570e... not a new machine but does the job. It says 16v---3.36A on the bottom of the base

So then split the wire for the screen and one for the amps...

Does this seem like a bad idea to anyone else?

I thought the acc was not designed to carry power, just be an indicator for when things are supposed to turn on. I would think that using the acc power for the monitor is a bad idea for that reason.

Also, I remember there used to be a debate over whether a screen plugged directly into the car's power supply would be in danger because the car power isn't regulated, it fluctuates wildly during start-up, idle, etc. This will almost certainly lower the life expectancy of your screen, and will likely lead to noticeable performance difference (brightness, lines across the screen, interference, etc.)
