imgur.comI don't know if it's true for other countries, but in India the most popular car-reversing tune is My Heart Will Go On.

Doesn't sound like it would be a very accurate reversing sensor. "Near, far, wherever you are..."

I think he meant the external alarm, for trucks and buses and stuff
That or it goes up and down in pitch accordding to distance
Near, ^far, ^^WHEREVER ^^YOU ^^^ARE

When I was visiting India the car I was riding in had a tune played by the reverse bulb to warn people of the car backing up. I don't know what song it was but I noticed some pedestrians singing along with it. Similar to this.

It could be a glass-break detecting microphone for an alarm system.

Looks like a tweeter to an aftermarket speaker. Turn on music and see if you can hear high pitched sounds coming from it.

doesn't make any sense to have a tweeter in the trunk though, you want line-of-sight and wouldn't hear it a bit through the seat... unless it's part of a more obvious setup to play music outside the car with the back open.

No but if its part of a higher end component speaker set up it would make sense. They just put it in the rear.

part of a higher end component speaker
looks back at the pics
Nah.

Yeah if they're not proud enough to pop a logo on that bad boy it's probably not any high end car audio manufacturer.

Just FYI, high frequencies don't travel through matter very well. Low frequencies are better at this. Cost doesn't play into physics.

No but it is possible for someone to install a speaker wrong if they didnt know better.

The little dot under the grille makes me think it's a stereo speaker.
Edit: i get downvoted for taking a guess? Is that how this sub works? Good times.

Generally people who are wrong get downvoted so that the correct answer doesn't get overtaken by jokes and guesses.

Speaker for a phone hands free kit perhaps.

Who puts a speaker in the boot
Boot=trunk

The length of cable suggests it dropped from above.

have you read the manual??

it LOOKS like you might be able to pull it down to release the trunk/boot hatch to allow you to escape.
EDIT: could you post the make/model of the vehicle?

Speaker/beeper for an aftermarket parking sensor system:

Aha, many thanks - looks like the exact model, too! I suspected it might be this, but haven't had the opportunity to get someone to stick their head in the boot while I'm in reverse ;)
Solved!
Winner!
Why in the trunk though? Aren't you supposed to hear it?
Running wires through the cabin of a car can seem daunting for some people. They probably figured they could hear the beeper from the trunk and said, "Eeah. Good enough".
Even factory reverse parking systems tend to keep the speaker in the back (just replaced mine)
You still hear it, and plus it kinda makes sense for the noise to come from behind you, since it is alerting you to obstacles behind you.
It also depends if your car has front sensors. If there are no sensors in the front there isn't much point in running all your wires up to the front unless you have the little screen that has to go on your dash.
I used to install these.
Yeah that could be. I'd probably run it through where the seats fold down and just leave it on the rear shelf. But then again cars are different, could be that they don't fold down in this one or maybe it's even an SUV/van
well, it looks like a hatchback, not nearly as much between you and it as with an actual trunk..
These speakers are usually extremely loud and sometimes don't have volume adjustment.
