ok so i upgraded my stock speakers to new new ones. my problem is when i open my drivers door the speaker will crackle and cut in and out. the connection to the speaker is tight. is there any other spots where the speaker cord could disconnect?the speaker also crackles under bass.

thanks

 

First things first, the crackle when you open your drivers door is a pinched wire being grounded. You need some slack on the wires in the doors and through the door jams, Remember everything moves in vehicles.

Second, if crackling under bass, you need a HPF filter. You have sub bass frequencies running through your door speakers. This crackling could also be a voice coil that is starting to rub also because of overpowering with a dirty signal (radio is clipping - overdriving the outputs on the radio/amps) or bottoming out from subbass.

 

ok thanks for the reply. first off whats an HPF filter? second how could the head unit only give bad signal to the one speaker and not the rest?

thanks

 

HPF= High Pass Filter. It is used to keep lower frequencies from the speakers.http://en.wikipedia.org/wiki/High-pass_filter#Audio

 

Its very possible its doing that to more than one speaker. Just sitting in the drivers seat one sticks out more than the rest. Also, it could be from the grounded wire making it more noticeable.

 

well, you were right it is all the speakers crackling under bass. so where can i get a cheap filter for the stock radio?

 

BUMP... anyone know where to get a HPF filter?????

 

Do they still sell those "bass Blockers"? It was a resistor or something that you wired the one of the speaker terminals and then connect that to the speaker wire. I remember those from a long time ago. that would be the cheapest way i think if they still sell them.

Have you tried turning the BASS down on your head unit???

Is it the stock head unit or A/M? Some aftermarket radios will have an built in option to apply a HPF to the front & rear speakers.

 

its the stock HU. the only way they dont crackle is if the bass is all the way down. also the bass block sounds like a good idea.

thanks

 

Search "bass blockers." They're nothing more than a capacitor that you wire inline with the speaker. Filters out the lows and protects your high frequency drivers somewhat. What do you have the "BASS" control on you radio set to? If you have it turned up at all, that could be the source of your problem.

 

Low_E_Red:

I thought that you found an installer job a long time ago.

 

so would these bass blockers help if it only crackles on certain songs? also when i took the speaker out of the door i noticed that it sounded great on any song with the bass up. it only cracks when the speakers are in the door, and the speakers are not loose.

 

Do you have the BASS on your EQ or tone controls turned way up. Most people mis-use EQs. They should be used to achieve the flatest response possible. If there isnt enough bass, you need subs.

 

the bass is fine i have the stock head unit and have the bass half way up and itll crackle like hell on certain songs

 

I just re-read this. It reminded me of an issue i once had. Could the cone of the speaker be hitting the door panel. I had this happen with some Infinity Kappa Perfect 6.1s in a rear deck. it did damage the cone after a while. (alum cone)
