I will ask a simple question, and try to make it easy for you to
understand. If you have a power wire going from the battery to the
amplifier, and the only fuse is at the amplifier, what happens if any
part of the power wire shorts to ground?

Mmdir2002, if you cannot answer this simple question, you have no business
answering questions in this group.

You have more one chance with me because I sense in some of your posts you
are truly trying to help (though most here think you are hopeless). Please
think carefully before answering. Thank you.
