Woofer sound distorted

the distorted sound coming out of your sub-w is actually originating from your audio unit, Have your audio unit check for possible repair

can mean several things. The crackle is subjective and can mean distortion. Distortion most of the time comes out of the amplifier. Could be you have blown a capacitor in the power supply of the amplifier, making it work with quasi half the voltage. There is no need to change the polarity on a speaker, because when one is not working infuse, it won't distort the music. You only could have difficulty with the stereo sound. It could be a bit unclear where the sound is coming from and could sound a little less powerful.Check the speakers on a different amplifier, to hear if I'm right. Only if you switched on sound while the amp was giving full power, you could have blown the speakers, but most of the time they don't give any noise after that.

Step 1:

Hate to say it, but possibly a blown speaker. To check this, do the following -

Step 2:

Insert headphones into jack to verify for sound there.

Step 3:

Unplug unit and open rear panel to reveal speakers.

Step 4:

Remove leads from woofer.

Step 5:

Using a multimeter, set to OHM (horseshoe) to lowest setting.

Step 6:

Apply red(+) and black(-) to speaker leads. Meter should read at least 4-8 ohms of resistance.

Step 7:

If no reading, then voice coil is blown.

Step 8:

If no meter available to use, the use a 9 volt battery by applying direct connection to speaker leads in an off-and-on fashion - You should hear a "click" sound come from speaker. If no "click," then speaker is blown.

Step 9:

If click is heard, and resistance on meter is correct, then the amp circuitry leading to the woofer may be blown = repair needed.

Simply put, burned voice coil. Either too much power can do this or not enough power with distortion. solution- if the sound is clear then its too much power- turn the amp down. If the sound is distorted and raspy- its not enough power and your getting distortion-get bigger amp.

bhurajiv,
Well it's a good thing that you are getting sound from the tweeter from the speaker cabinet with the problem, that eliminates one of the possible problems; your wires are connected!

If your other speaker sounds fine, the first thing to try is to swap your speaker wires with the one that sounds fine. If the problem speaker cabinet still only produces sound from the tweeter, the problem is within the speaker. If the problem goes away, the problem is from your electronics.

If the problem is within your speaker and it is still under warranty, find a authorized repair location (http://www.cerwinvega.com/service_center.php).

Problems within the speaker can only be one or more of the following: 1) The drivers not producing sound have been blown; played with either too much power and/or distortion. Distortion is created when you play your music too loud with a amp not able to reproduce what you are looking for in sound, the speaker itself can hear it before you can.
2) The speaker cabinet has a crossover inside which directs the proper sounds to the proper driver. This crossover can have components that have been broken be either #1 or from exsessive vibration.
3) There are wires inside of the speaker cabinet that have been disconnected. This can happen over time or if someone reaches inside of the cabinet through the port and pulls on the wires; like a young child or pet such as cats.

If the drivers in question just one day stopped producing sound, start with the easiest solution, #3 then #1 if you can suspect anyone could have played your speakers other than you.

To diagnose the problem, you first start by removing the woofer and confirm that all of the wires are connected and in good condition. While the woofer is removed, to eliminate that there is a problem with the speakers, temporarily connect the mid-range and woofer, one at a time, directly to the wire coming from your electontics, if they produce sound the problem is within the crossover network, if they do not produce sound, the problem is with the driver itself. Replacement parts should only be purchased directly from Cerwin Vega directly (http://www.cerwinvega.com/contact_us.php)

Your sub woofer is not mean for voice sound...check that you have connected the systen up properly and that you have put the sub woofer into its wn connection..if it is in the right connection the woofer could be blown.also try decrease the midrange hurts on the woofer

Hello css42103,

You did not specify the impedance or the model of your Audiopipe replacement woofer but if it is the TS-V6 DVC 6.5", then the impedance of each voice coil is 4ohms. If you wired the coils in parallel, you now have a 2ohm load to the amp. At 2 ohms, the amp tries to produce more power, and even at moderate volume, can be driven into clipping causing distortion. Not good for the amp. Definitely not good for the woofer.

I'd try wiring the woofer coils in series and see if it stops cutting out.

Hope this helps.

well if you hear a rattle sound its probably already blown...and the amp could be drawing too much power if the radio shuts off...make sure all your wiring is correct. also if your car is off and you turn it up it will most likely shut off cause the battery cant handle it. but as for the sub i think its blown. good luck

The "voice coil" inside the woofer must be rubbing against the "yolk" plate. Meaning = it is mechanically blown(damaged) to a point but electrically intact.
My sugesstion is to take out the damaged woofer and "google" for a mew woofer with the correct impendance and size and mounting holes. If you dont know thw impendance, then you should go with at least 8 ohms. More ohms = less risk of overloading the amp. whick can cause a fire!

Good Luck!!
