  • Splicing Power from Head unit for lcd screen??

    I was wondering if it a good idea to splice the 12v power from my stock head unit on my Mazda w/ Bose system to power my new 7in lcd. The screen will consume 8-12w. I was wondering what the potential problems would be with this setup. any help would be appreciated.

            1. The specs say it requires 12v, as opposed to an input range. Considering there's not a car out there that will provide a stable 12v, you need a device to provide it (also known as a regulator) or some other means of providing stable 12v.
            2. DigitalWW has an email address and a phone number. Did you even think to email Armen from DigitalWW for more information?

                It fluctuates, as does all the car's electrical power.
                Mine goes from a low of around 9v to a high of 14v, depending.

                I'll say it again: You need something to provide a stable 12v for that screen, lest you risk frying it.
