High current drain subwoofer

I have traced the problem to the #3 fuse behind the glove box. With fuse in and everything of I draw .17 amps remove the fuse and it drops to .03. What could be keeping the subwoofer on with the key off. This is the columbia edition with 7 speaker system plus sub and tweeters.

Somebody miswired or screwed up the subwoofer amplifier power wiring, there's a "trigger" wire that is supposed to turn it on. Most head units provide a trigger wire to connect to the subwoofer amplifier to turn it on & off.
When you have a choice, buy American.
