Has anybody noticed a buzz sound from the tweeters, like a vibration or something like that, when it's played loud (not even too loud). This is with the HIFI Upgrade.
I exchanged the tweeters with CDT audio in the front pillars, and everything was fine, until I started noticing this vibration sound, more like a buzz. So I put back the stock tweeters, but the sound is still there. I have the bluetooth option, and when somebody calls, sometimnes it's hard to understand the voice, because of this sound.
Has anybody noticed that in their cars? What do you think it is? the Amp? The speaker? I have no clue. I am about to unplug both tweeters, cause it's pissing me off big time.

Thank you

 

No Buzz here. I'm actually pretty impressed with the HiFi upgrade...it exceeded my meager expectations.

 

I've heard what you are talking about, my girlfriend has the bluetooth and I hear the buzzing more while on the phone through the speakers with the bluetooth.

 

I've heard the buzz, But I just changed out the tweeters to Infinity's and i think it's gone.

 

I have not buzz, but I have no Bluetooth. The HiFi sounds fine.

 

Yeah, nevermind. I know what it is.
Turns out the midrange and tweeters receive the same frequency (they are actually coming form the same line output from the amp), and since there's no crossover, the tweeters distort a lot, and that's the buzz I heard (specially when voices are heard, that's why it is more noticeable with the bluetooth audio).
I am in the process of getting rid of that stupid little amp, and put a real one instead. Then I will make each one of the speakers work the way they are supposed to do. I will let you know of my results next week.

 

No buzz in mine, no bluetooth. Hope the other amp works out.

 

True about the same signal going to both but there should be a capacitor in the a-pillar to cut out the lower freq's going to the tweeter.

 

Or you can buy a bass blocker from Crutchfield for the tweets. They work pretty well, and they only cost a few bucks!

 

The bass blockers are nothing more than capacitors.

 

I didnt see the capacitors....
Are they the little things wrapped with a black rubber?

 

yup
