Default How to Wire A Headunit OUTSIDE of the CAR?

Hi

I bought a oem cd player 99/00 civic model off a local forum. I wanted to know how to hook up the cd player while it's outside the car to demo it sorta like they do in stereo shops. What kind of power do I need? Where would I ground it? Regular AA battery? I don't want to install it in my car just to see if it works cuz all my wiring is a mess. I also need to know if it's an Si cd player or just a regular EX model. It's a single DIN unit. Can I use the 1 and 6 button technique to get the security code for it? THX.

S/N M98F318720

MODEL # 39100-S02-A1-- last couple #'s got scratched off the label

REF NO CQ-JH5812Z

MANUF DT: MAY 2000

You could hook it up to a car battery. You can also use a 12volt power station, used to jump start cars. Just hook the 12volt constant and the 12volt accessory from the radio to 12volt Positive and the ground from the radio to Negative. Use any 4ohm speaker to test the speaker output from the headunit.

You need the same power that's in a car... 12v, negative ground. You'll need a 12v power supply, which plugs into the wall, and converts 120v ac to 12v dc. Or, like the above poster said, a car battery.

LOL!!! That made me chuckle... Try it, and see what happens.

To my knowledge, they're both the same.

try using 8 AA batteries in series... at least you'll have 12V and might actually light the thing up seriously, you need an AC to DC power converter, or a 12V battery... radioshack has those 12V batteries for big flashlights or science projects etc.. probably between $10-$20. no idea how long it would last though...

do you know which wires are what on the back of the radio? I have the helms manual which has all that info if you need it... just let me know

Your computer power supply unit will work well.
4 pin plug: Yellow= +12, Black = Ground.
You'll have to disconnect the PSU from the computer completely though.
Then short pins 7 & 8 (grey and black wires) on the ATX connector. Shorting pins 14 & 15 (Green and black wires) will turn the PSU on and off.

Hey thx everyone for the great tips and help. I had a spare car battery so I hooked it up to that and didn't shock myself to death heheh. With some help from a friendly honda parts guy I was able to get the CODE for the HU. Turns out it was a Si cd player. Lit up amber and everything. Much props to everyone that responded.
