Buy another set of cables and a fuse and connect the carpc seperatly.
Your cables are probably too thin and can't power on both.
I've had my Carputer installed with a Opus 90w PSU (full spec in sig below) for about a week now, everything running fine, but with no sound as Amp was not yet installed.
So today I install the 1400watt Amp. I wire it into the 8 Gauge Power wire and Earth that I have already installed for the Carputer. Now the Amp powers up fine, but the Carputer will no longer Power up. No lights nothing. I disconnect the Amp and the Carputer works fine again !?
Both the Carputer and Amp are running of the same Power and Earth Cables. 8 gauge cable.
Is the Power cable to weak for both the Amp and Carputer, is the Amp draining all the power ?

1400watts and a CarPC on an 8ga. wire? ......Run another 4ga line seperatly for the amp and you should be fine. "1400w 4 channel amp" eh? 350 watts x 4? No name brand listed either?
8ga wire is too weak to run something as power hungry as an amp and a computer. best bet would be to run fused 4ga wire from battery to trunk, install a fused 4ga-dual 8ga wire distribution block and run to each device respectively. Then take a 4ga ground wire and run to a ground distribution block and wire to the amp and puter. Most Ground Distribution blocks come with a 1 4ga to 4 8ga distribution. This should solve your problem. Also make sure that you main fuse on the 4ga wire is strong enough not to blow when u have the amp and the computer on
Another reason for having the thicker wires is voltage drop. The thinner the wires, the greater the drop in voltage on the wire. If the wires are too thin and/or too long, the voltage could drop enough to trip the low-battery settings of your amp and computer, or at least cause some sort of small-scale electronics havoc.
