    using radio power wire for lcd

    Okay here is a quick question i have, i currently have a pioneer avic-n2 in my car, but i want to put in a lilliput lcd in, now what if i use the gm radio adapter and wire the lcd monitor to that? Use the red power wire and black ground wire and wire them up to the cig lighter adapter. I know everyone is going to say, just use the opus, but i would like to know if anyone has tried this or if it will work. Because then you get the automatic power on/off with the car and i can run other things to my opus like my xbox.

    First of all, DON'T USE AN OPUS WITH YOUR SETUP. That has been addressed in your other thread.

    Second of all, I highly suggest planning out your hardware before you start deciding where you're going to tap into electrical circuits in the car.

    Third of all, you're talking about your opus like it's some magical piece of kit that will power anything & everything you want in your ride. It has a limited capacity, and even if it did work for your scenario, you'd likely overload it with all you want to power with it.

    Again, I am going to direct you to the FAQs: http://www.mp3car.com/vbulletin/advfaq.php
    My suggestion to you (and everyone else interested in this hobby) is to research and plan everything. Do it systematically and logically. Planning where you're going to pull power is something that you should do after you've made some hardware purchasing decisions. You shouldn't make hardware purchasing decisions until you understand what all is involved with that particular hardware.

    So slow down. Do some reading. Learn some things. Gain an understanding of what you're about to undertake.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Okay, i get the opus only works with certain set ups, i was under the impression it was a universal power supply, ive done more research and ive found http://diy.sickmods.net/Our_Products...nverter/About/ and use an ATX to power my xbox, which is great, solves some problems for me, but i still need to find an easy way to power my lcd screen, would it be feasible then to use an atx power supply to power the lcd screen. Also i dont see why it wouldnt work to use the gm harness and connect the wires for the car adapter to the red power and the black ground. Is there some reason why it wouldnt work? Would the power surge or something?

    anyone know if this will work, will i over power the lcd and blow it? Its a 12v for the headunit and a 12v car adapter so it should work.

    It should work, but I would verify the power requirements of your LCD to make sure the thinner (high AWG) wire of the radio harness will support the LCD's power requirements.

    That depends on the screen. Some require regulation. some do not. You need to read the specs of the monitor(s) you're considering.
    As a general rule, Xenarc brand LCDs do not require regulation and Lilliput brand LCDs do.
