homemade cables and blown tweeters

I recently made a set of 25 foot cables to send a feed from the normal output of a Parasound 850 pre-amp to the low level input on an Earthquake sub. I terminated both ends of the 12 AWG monster cable with gold RCA and solder.
Within a week i blew tweeters in some 22 year old speakers. Thinking that it was age i retired them and bought some new Paradigms. Within a week those tweeters are blown. IT could be the power amp???, Pre amp?? but i ran those in a config using the sub and high level inputs for 2 months w/o a problem? I would like to use the sub, but am unsure if it is the sub, or the cables. any ideas??
Are interconnects not to be 12 awg, copper? Any help appreciated
thanks

great explanation
thanks so much
should have purchased those interconnects instead of making my own.
Not shielded, just number 12 zip cord.............
I will replace the tweeters on the paradigma and
run w/o sub till i get my courage up and buy some quality interconnects.
