well folks the techie at florida electronics says there's nothing wrong with
the amp confirming the techie here...so it's on the way back(don't know why
it blew the black widow so soon though),but I have to order a new 12"..but I
bought a new srm450 in any event so now I have three,hope that's good hehe..

I thought you measured 12V quiescent across the driver?

The funny thing is if I press down at a certain angle on the negative line
that goes into the basket on the black widow,I get continuity(doing it with
a plastic object I might add)and I was able to get a few responses from the
12" mackie..it's as if a wire is loose somewhere like a light bulb when it
blows,and u can turn it to get the filaments touching again(sometimes).any
diagrams online how these speakers are made up..the coil winding etc?..I'm
gonna take it apart to see what's going on in there..

Usually the way those fail is because the coil overheats and melts through
somewhere. Sometimes the spiders get screwed up and the coil gets scraped
and damaged that way, though. Occasionally the tinsel wires go bad.
