I have an 09 TL tech at I've had for less than two months. I've already replaced almost all the speakers (they were blown when I got them- long story, some of which I've already told in the 4g forum).

The technician at Radley Acura told me that the amplifier is in the trunk under the lining, so it tends to overheat because there is no air circulation. This causes the output to increase and can blow the speakers.

Has anyone else encountered this? If so, is there a way to remove some of the lining or put in some kind of air vent or fan?

If the speakers blow again, I'll probably just fork over for some better aftermarket ones.

 

How high is the audio volume when you listen to musics ?

 

Not very high- usually 12 or 13. The second I hear any distortion I turn it way down.

 

I have'nt experienced that problem,i have one aftermarket amp and the original.If you wish you can locate the original amp and remove the liner temporarily to increase the airflow and see if the problem comes back.

 

Yeh, loudness doesn't usually kill speakers, but loudness + distortion together always do.

 

I've brought mine to the dealer a few times because I've blown the speakers and its under warrantee. I must say that I listen to loud house/techno music that tends to be bass heavy however. I pretty much have whats coming to me. But you know what???? Thats what warrantees are for. I just bring it in, leave it in route to work and pick it up later on that day or the next day. And the cool thing is, you get to try out other Acura's. Pretty sweet deal if you ask me!

 

For whatever reason, I blow my front passenger door speaker every two months or so. It's been an issue with every 4G I've owned. I don't blare my music, either. Who knows...

 

I have only had my front speaker blow only once since my 09 was new. I was told that closing the door hard is what causes the problem. Since being told that I have been careful closing the doors, and have never had a problem since.

 

It's all about pushing the limits in every aspect with these Acura's....

 

Perhaps I am all alone in this train of thought, but why should I have to baby my door lest I blow the speaker in it? Is there no way that Acura could not have thought about the fact that passengers, kids, etc sometimes slam doors and prevented this somehow?

 

This doesn't make any sense. Slamming the door may cause a wire to pop out (it shouldn't, but it could) but it shouldn't blow the speaker.

 

Think sir, if you slam the door you cause the the speaker to travel the length of its suspension. Over a period of time of this happening, you will hear a rattle. Makes plenty sense to me.

 

^^^^^

In this case, this should happen to all automobiles, not just on the 4G TL.

 

Exactly- if they are going to put speakers in car doors, they should test them and make sure they are built to withstand the impact of the doors slamming.

Anyway, the speaker problems I had affected all the rear deck lid speakers as well, so even if slamming the door is the culprit on the door speakers, there is still another issue.

 

The amp is probably defective. Have them replace it or you could by one for around $275. As for the speakers, their are just pieces of crap. Just replace them with something better.

 

Depends on quailty of speaker and how it is mounted. I've had two front speakers go bad and when I strarted paying attention how I closed the door, I have not had any trouble since. That since 2009. Trust me, I like my windows down and music loud. I had the dealer line my rear deck with a dyomat material, and that took care of any rattle in the rear.

 

Its not the amp. We have replaced both front speakers, one of them twice. There is no way my lady pumps the volume long and hard enough to over heat an amp. The only time I've had issues like that was on a 5 hour road trip through the desert with an amp under the passenger seat.

OP, if the car is out of warranty, upgrade to some better speakers.
