Maybe with the use of relays...
Search for others with inverters that have done this!!!
I hope this hasn't been covered ten times already, I searched for it but didn't find anything.
I am building my first version of a carputer and have a question;
My system so far consists of a Pioneer head unit linked to an Amp and Crossover in the trunk. My understanding so far is that the 12v line connecting the crossover and amp in the trunk is live all the time but that the devices only turn on when they receive a signal over the Remote Turn On Lead that connects to them from the Pioneer, correct?
Assuming that it correct and that I connect the power for the PC, through an inverter until my Opus comes, off the 12v line that goes to the trunk that means the inverter will be powered up 24/7. does anyone know if the remote turn on lead from the dead unit can be used to activate the momentary contact power switch on the motherboard?
search this forum for Relay and Inverter. There are a bunch of guys that have their inverters turning on and off with the remote wire.
If I understand here you are talking about the ACC line, I am talking about the remote turn on lead. The info on relays and ACC is good to know, and I didn't know it before but what I guess I'm really asking is when you turn on the car what happens down the remote turn on lead (RTOL from now on)?
OK, I think I'm in learning mode now, my new understanding is:
RTOL is same as ACC but powered on and off with headunit power, right?
Knowing this can I just run a power wire from an ACC point in the fusebox to the inverter and then ground the inverter to chassis?
Big thanks man, that helps a lot, doing more Google research now.
Second question (still happy for info on the first too tho )
I assume I will have the infamous reboot while cranking problem, if so can I fix it with a second battery?

No, you don't want to power anything(big - CarPC, Amps etc. ) with the ACC or the RTOL, they should only be used to signal the devices that the car is turned on. They get their power seperately as you said in the first post.
The ultimate CarPC - Wow!
Many inverters will survive crank. I know mine does and if you're eventually going with the opus, I believe that does as well.
