    I want to put my HF radio in my vehicle. I already have a 4-gauge wire running from my battery to a 900 watt subwoofer amp. Can my radio and the amp share this wire or do I have to run a separate wire? Do I have to buy a huge diode to isolate the sub amp from the radio if they share the wire? I obviously wouldn't be running both things at the same time. Thank you!

    It Should work fine, If you operate one at a time.

    I would Fuse each separately.


    Have Fun.

    One possible issue.

    Common mode current flow on antenna interconnection wiring is a given, no matter how and where you mount the antenna. If you properly choke it off, you won't have any issues. There are article on my web site which cover choking of both coaxial and control lines.
