    It has more to do with buying the right part for the project rather than buying something based on brand name or price. If you buy something rated for 60A, and you only draw 40A, then you are fine. If you buy something rated for 40A, drop in an 80A fuse and start drawing 50A constantly, you're asking for trouble.

    It's the same story with a subwoofers. I've seen posts on other boards of people asking why their sub isn't working, and wanting to know if it could be the amplifier. After a few question you find out that they are pushing 1200 watts RMS into a sub rated for 600watts peek.

    It's all about common sense. Use the right part for the job and you'll be fine. I wouldn't bother with the Digital stuff unless you really like bling. In the end it's just something else to go wrong. I would also avoid distro blocks that are positive and negative combos. Combining the two in one enclosure is just asking for trouble in my opinion.

    And you didn't really ask a question in your pic.
    But your diagram and logic is correct. You would use an ignition-switched line to trigger the relay, which would be between the distro block & the inverter. That would power on the inverter when you turn the key on, which is what I believe you ultimately want.
    Yup thats what I was wondering, the only thing that I had a problem about was does it hurt going from a 4GA wire to that small relay and back into 4GA again?

    Relays are rated for amperage, just like fuses. As long as the current draw is not more than the rating for the relay, you will be fine.
    Have you looked in the FAQ yet?
    How about the Wiki?
