Re: Marine grade speaker/subwoofer wire?
i have been an audio installer for years....never used marine grade wire, has never had an issue with wire frm installs years ago. been back to boats i have done in those early years to replace different components, but NEVER wire. i have seen copper go black in both cars and boats alike, a little bit of emery cloth gets the ends all copper n purdee again. IMHO i think a lot ( not all) marine grade stuff is joke, just to get a few more dollars out of an owner of a high priced toy...kinda like the extra $$$$$ bikers pay for stuff with the harley logo on it, when the same generic piece is 50 percent less and runs off the same assembly line. most of the time i dont even use marine speakers or head units...never used marine amps or wire. I would test the sub for "popping" with a 9v battery, and your sub wires with an old "test" speaker at the amp and sub location
