    Default Marine grade wire for track car

    I am looking to order some primary wire to run power from the battery POS terminal into "PDM" or relay box rather.
    I went to my milspec vendor's site and they only had 8 awg at $4.xx . ft (hell no) Plus I want 6 gauge. So I came across Marine grade wiring. Apparently its more flexible and "better" than regular automotive wire.
    Has many more strands.

    Has anyone used this kind of wire before on a car? Any plus or minuses?
    I did a quick goggle search and came up wit this:

    Boat vs. Automotive Grade Wire - boats.com


    Thanks

    The rule of thumb is car parts don't work on a boat, but boat parts on a car is usually OK, particularly on race applications. The marine environment and duty cycles are much more severe than automotive applications.

    I've not used it because I haven't been faced with that choice, but I probably wouldn't hesitate.

    Both wires look much inferior to what I use. Because most BMW (naturally) batteries are in the trunk, the battery cables are in excess of 10ft long. They are extremely high quality(the old stuff that is). I actually reused my 1987 cable and it still looks like new, including the terminal.

    That may be true. Because of the current they need to carry over the length. But I wouldn't call the cables I mentioned inferior, I just think its a different application.

    6 gauge @ $1.29/ft and it's the really good stuff.
