A place to talk about anything well just about anything (this is a family show remember).

I'm with Komodo on this one. Unless your mate is a qualified electrician then leave it alone.

Mine was set up by Camel when I bought the camper.

Get a 240-12V converter. Not very exy, Coleman make one and I'm sure you could find one in most camping stores. (look something like this

Then just wire up a neg and positive from the battery, to the neg, positive, and accesories wire on the CD, with a plug. (wire the Acc wire to the positive so when you turn it off, it doesn't loose its memory).

Done.

Don't stuff around making your own way of converting 240 to 12.

Because the convertor will have a Cig plug attachement, you'll need to work out which is +/-, and make up some sort of plug so you can either plug the stereo to the car battery, or to the convertor.
Hope this makes sense cause I typed in a hurry, but it shouldn't be all that difficult.

Most of those are limited to 4-6amps unfortunately. And most HU these days use MOSFET internal amplifiers to make 45w cer channel (around 16-17 watts per channel RMS) and draw about 15 amps (fluctuating)

fairynuff.

What about a car battery charger? Hook the +/- right up to the head unit? :idea: :mrgreen:

Where there's a will, there's a bodgey way :lol:

connect the battery charger directly to the battery and run the radio as per normal from the battery - most battery chargers are 4 - 10 amps and have some ripple from the 50htz AC the battery should act as a filter cap and produce pure DC for the H/U. Also using the battery capacity for peak draw periods and using the charger to replenish the battery during lower draw periods

Could always get one of these. Has a built in safety switch.
