Default Blown speaker draining battery

I notice my driver side front speaker going bad a few days ago... Started out as just a low output from speaker then no sound at all. The next day battery was dead. Also, I noticed that my audio fuse was blown... Replaced factory fuse underneath back seat, but fuse blew again... Could this be the factory amp going bad, or did the bad speaker just short the circuit?

i would try disconnecting the speaker before you put the fuse in next time...that will narrow down the problem really quick

Okay, first of all, a speaker can't drain a battery; it can only take whatever signal the amplifier pushes at it, and if the sound system isn't on, it'* not doing anything to the battery.

I should clarify one point here, though: If you've got a separate amplifier that'* powered at all times, not just when the tuner/pre-amp switches on, then that component could drain your battery (and if it'* going seriously bad, I could see it frying a speaker, too).

All that aside, though: when a fuse blows, that circuit is now out of action, since the blown fuse has turned off power to that circuit (Duh), but that also tells you that the wiring upstream of that fuse must be okay, too, since the fuse could not have blown if the power didn't need to go through it to find ground.

Unfortunately I can't tell where these symptoms are leading, because they seem to suggest at least two problems, not just one: You're blowing a fuse, so there'* Something Bad on that circuit, but you're also draining your battery, which means that there'* another power drain somewhere that is _not_ blowing a fuse.

Maybe if you give us a little more detail on your audio setup, especially the parts that aren't factory-installed, we can get some better ideas.
