Running modern accessories with positive ground?

Abject apologies if this has been discussed to death, I searched but might not have used useful terms. Please feel free to reply with a link to a previous discussion.

I have a Longbridge BN4 with positive ground. I'd like to build a separate, removable box with a small receiver, MP3/Sat radio connection, a couple of speakers, and couple of negative ground power outlets for phone charging and a gps.

Nothing particularly Hi-Fi or power-intensive..

If I build the thing out of non-conducting material so as to to eliminate any possibility of grounding to the body, what do I have to do to other than reverse the leads on the inline-fused power feed for this contraption?

Thanks!

Dave

Well Dave
Isolation is one way to go. However, it has drawbacks.

OTOH, reversing the polarity in your car is a relatively simple and much safer method to use.This will allow the incorporation if newer Negative ground equipment upgrades at a later date.---Fwiw--Keoke

OK - I see a lot of information about that, so I'll check it out, Keoke. I guess for some reason I thought it was important to keep it the way it was, but if the next owner down the road wants to change it back, he can do it just as easily, right?

I'll still want to put the sound system in a separate removable enclosure.

Thanks -
