Power Rail for head unit?

**Mage** · 10-19-2004, 12:03 AM

hey have a question, it's for another project of mine.

I have a spare rampage adr-14 head unit that I plan on putting in my home pc would the 5V and 12V rails from the power supply work for it or do I need to run a second power sys I have Allied True 450W PS.

thanks

It will work, only it will give a 12v signal and your battery gives like 13,8v it can make a difference (i know from experience), you wont need the 5v i guess?

i would recommend to keep the volume low, a power supply isnt made to supply the amount of current a head unit draws, nor is it designed to deal with the fluctuating power requirements

thanks for the info Since I'm going to plug it in to the line in I'm going to control it via the pc Over the Vol control.

it would prob be better to just pick up a 110v to 12v transformer
from the shack for 6$

Thanks, I have one but I'm trying to keep my PC down to just 2 plugs (mon and pc) for this. I rather power it inside than out, That makes it a nicer install if you know what I mean.

internat splice to nab power from one coord, internally it gets its own power.

might be nice spliced directly to the PC power supply, but wont be so neat and nice when stuff is on the fritz.....

what?

you said you didnt want a separate power plug because its messy. you can tap AC power from inside the computer case to power the 12 volt radio supply. that way, your radio will be running on an external supply afterall, but you still have only one power plug exiting the case. that power plug just powers both the computer PSU and the 12 volt power supply.
