Audio Issues
I just bought a 2001 GS430 with Nav and ML. I get no sound or movement from the subwoofer. And I get no sound from the tweeter. The front and rears speakers work. I read through the manual and did not find anything about being able to turn the subwoofer on/off (like many aftermarket head unit).
Could it be a bad amp? Is there fuse for subwoofer/tweeter?

I don't know about you but I tend to fix anything that breaks or is not working on my cars.

the tweeters you probably wouldn't be able to tell are working without a voltmeter, since the sound output is above what our ears can detect.
the sub on the other hand, check all your settings, make sure your bass is up, fade is even. if that doesnt work, check the actual connections to the sub's terminals. if that doesn't work, check the connections on the factory amp located behind the glove box. if that doesn't work,youll need to pull your radio and check the connections on the back of the radio.
if the sub was blown you would hear a buzzing sound instead of clean bass like normal.
much outside of that, it would have to be either a fuse issue with the amp (either external or built-in fuse) or a problem with the wiring. many people have problems with the ML sub for some reason, though it was supposed to be the premium audio product. if the amp was bad your door speakers wouldn't work either, as they recieve power from it too.
also, go to the sticky at the top of the forum labeled "cool hidden features" or whatever, and search for the radio setting trick. Try that, and see if you can adjust your outputs to make the sub come back.
if all else fails, go aftermarket.

I would check under the rear deck and see if there is any evidence of the previous owner having installed a aftermarket system. They may have cut wires at the sub and tweeters to install their aftermarket stuff and not taken the time to hook everything back up correctly when they uninstalled it.

Wrong, you can detect if tweeters are working. You'll hear very high pitch sound coming from them. If tweeter's frequency will be above human's ear detection range, why would they put it in the car at all, if you cant hear it? Think about infra-red headlights or horn with <5Hz frequency.

i also tried the audio trick but i dont think it works on my car. assuming it is the one where you have to hold climate + audio and turn parking lights on and off 3-4 times.
will have to check the amp and back of nav to see if there are any connections issue.

when my ML sub went out it didnt work at all ! not a sound out of it ! my best guess would be blown tweeters and factory sub ! cause the front door speakers are connected to the tweeters on the same channel of the amp ! and since the front and rear speakers are working that leads to blown tweeters and theyre still connected when you pull the door panel off !

and actually, speaking of IR headlights, cadillac has had a combo night vision/IR camera system in their DTS for years now. just not headlights

the frequencies i'm referring to that 'cancel' (wrong word, i suppose offset would be more appropriate) compensate for the 'in between' frequencies that will cause your ears to hear a muffled sound.

no no, you can hear certain frequencies that the tweeters are putting out but it's nearly impossible with the rest of the speakers running.
