Car system played through 120 ac HELP

[marvontherim]

I am building a BBQ island and I'm installing a car stereo system in it. I have purchased a JVC system and a converter.
The converter transformes 120 AC to 13.8 DC current.
Now the JVC has a number of leads 8 for speakers 1 for power to ignition 1 direct power to system 1 to ground and 1 for an amplifer.
I know I don't need to amplifer or the ignition leads because I don't have them. I can attach the constant hot lead to the converters positive terminal.
My question are:
1. What do I attach to the converters negative lead?
2. Will the converter work on a car stereo system?

Thanks for your help.

Basically, you'll run a wire from the converters + out to the amps "Batt +" and "Remote" then you'll run another wire from the converters - to the amps "Batt -" terminal. Hook up your speakers as normal, and you signal input (RCA's) and sit back and enjoy some tunes.

Still confused.

Hi Francious70
Thank you for responding. I am a little confused.
I only have 4 leads aside from speakers comming from the car stereo.
1. Black (to be attached to the car body or ground)
2. Yellow (to a live terminal at the fuse box)
3. Red (to an accessery terminal at fuse box)
4. Blue stripe (to a rempte lead or auto antenna)

Because I don't have a battery or fuse box I am using the converted to transform 120v ac to 13.8v dc
The Yellow lead from the stereo goes directly to the + out from the converter.
The Black lead goes to ground or to the frame of the BBQ.
The Red lead doesn't seem to be needed????????????????? not sure
The Blue stripe lead also dosn't seem to be needed????????not sure.

When you talk about Batt + or - I don't know what you mean. Can you clarify?

Thanks

Your converter or power supply should have two leads one plus (+) and one negative (-).

As you list the wires from the car stereo:

1. Black - This will have to connect to the negative (-) from your power supply (converter).

2. Yellow - This wire is the one that keeps constant power to your stereo for channel memory and clock settings. It will have to connect to the positive (+) on your converter.

3. Red - In a car this would connect essentially to the ignition switch so that turning the key on would turn the unit on. I think it usually provides the main power as well. It also has to connect to the converters positive (+).

(Yes, both the yellow and the red will connect to the same wire on the converter. Your stereo will lose radio presets and clock time when you turn the converter off.)

4. Blue - Remote lead. You don't need this lead. It goes hot +13.8volts when the stereo is turned on which would be used to remote turn on an amplifier or activate an antenna. (Some even have two, one for remote antennae which only goes hot when the radio is on and another for an amplifier remote turn on.)

Make sure about polarity +/- from the converter, you don't want to mix those up. You shouldn't likely be attaching anything to your barbeque.

Hope this helps.
