is there anyway to power up a HU without installing it into a car?
i have my 880prs laying on my desk, i just want to see the display and get familiar with everything since i have a few more days until i install it

Sure there is.

U need to have one of the following
a car battery
or
a AC to 12V DC power converter
or
A computer powersupply with atleast 10amps on the 12 volt rail

Then you just hook up 3 maby 4 wires.

Ignition wire.
Constant power
Ground
sometimes illumination

yep just hook up the constant wire (yellow) and ground to your bar battery and you can power it up or u can get a $20 ac to dc converter from radioshack. i have one they always comeint handy at some point of time.

U also need to hook up the ignition wire or it wont turn on.
If your deck has the illumanation wire you will need to hook that up also or no display for you.

Not true. Neither the illumination, nor the the dimmer wire are connected on my 880. Works fine.

you should just need to touch the red (or maybe its yellow) and black wire to the 12v battery under the hood of your car/truck

okay so the yellow/black wire connects directly to the batt.

but where do i hook the ignition wire up to?

just twist the red and yellow wires together and hold them on the + terminal and hold the ground on the - terminal.

thanks for the tip, i tried it a few days ago when i had some spare time...
i hooked up the ground to the - terminal and the power and accessory(red wire) to the + terminal on my car battery and the HU powered up with no problems
