ive heard about this a long long time ago. i made a cd just for it... i blew my 10in 600W MA audio sub with it... i went and bought 2 of the exact same kind and a new amp and it plays it pretty good in my bird but i tried it on two girls and it never worked
.. so i let my friend try it on his subs... 2 MA audio 12's 700W he blew a fuse.... so definatly you want to be careful when trying this
