Fitting a radio to neg earth?

[motown_junk]

Hi, I've recently been given a 1965 traveller and am in the process of restoring her (slowly and on a budget!). I'm going for original look as far as possible, but with a few mod cons - one being that I'd like to fit a radio / cd player. However, I'm aware that the negative earth on the car can cause problems - how can I get around these as easily and cheaply as possible please?

Also, I'd appreciate any thoughts on the best place to mount a radio under the dash and how to do this? She has a heater unit, so it can't go centrally, there's not a radio in at the moment.....

Thanks!

Negative earfh is what all modern cars have, and what most modern radios need to operate. Just to save confusion, do you mean that the car is at present POSITIVE earth, as original?
Easiest way, if so, is to convert to neg earth - easy, and free http://www.mmoc.org.uk/technicaltips/Ne ... Earth.html
