ok guys, well ive got a 97 explorer, and im putting a carputer in it. first off, ive be told that some home LCD's are 12v inside, and they are converted to AC power to work in the house...if thats true, how can i find out, and how could i power the LCD off of say the computer's power supply(regulated 12v)?
also, inverters...how would one of these work to power the LCD and the computer(if the first part of my post is false/cant work) some say theyre great, and alot say that it causes "noise" etc...they wont survive engine crank, etc...i really need help, im so ready to get this done, but theres little things like these that keep me from ordering all the parts and getting started (although these arent really "little things" lol...)
thanks guys for any help in advance, and sorry if i posted this in the wrong forum, i looked and couldnt find any other place to post it...

Yes it is true that some LCDs built for home operate on 12v... You just look at the power information on the back of the screen. It should say somewhere on there what voltage it takes. As for taking the power off the PS on the carputer, we recommend that you don't do that. The PS in most carputers are built with enough power to just power the computer itself and whatever little plugins there are for it (mouse/touchscreen, keyboard, etc). It'll be best to power the monitor on it's own source.
If your monitor doesn't run on 12v, then use the inverter. Many brands are great but we prefer Vector. They use a modified sine wave while inverting so they provide clean enough power to your monitor. Some of the "lesser" models use a system that doesn't clean up the power enough for AC devices. As for causeing engine noise, that problem lies in the installation. If installed properly, there will not be an issue with it. Most amplifiers eat up a lot more power than inverters, so again make it a clean install.
If the computer was made for the car specifically, then you shouldn't have to power it on an inverter. It's most likely you will have to wire it into your electrical system.
Hope this helps. Ganbatte ne!

True dat! Majority of engine noise is caused by differences in potential on the grounding side of things because of the path electricity has to take(through various body parts made of different metals). So make sure u get a good ground, if there is paint scrape it away and use some star washers. As far as a power supply for your PC try this website www.mp3car.com it could help. Im ordering stuff from them to try and build and install my very own car computer to get 7.1 surround sound in a 98 M3. Good luck and One love!
