  • kelaro75771 Sep 25, 2008

    when i installed this stereo, i turn the volume up around 17-20( volume tops out at 40)
    ,after a few seconds the speakers started to sound as if there were bare wires touching metal,but there was nothing wrong with any of the wires,i bought new speakers,exchanged stereo for another one and still got the problem.when the fader is only on front or rear theres no problem but when its balanced the problem starts.

It seems you needs more power to maintain the level of good sound.Maybe the maximum volume is 30 - then the mininum is 15 and you can't hear any cracking sound. If you exceed 15 the minimum, as you said starting 17 - 20 you hear crackling sound .Then you reach ,what they called the "cliping level"so much distortion and crackling sound,your stereo too small to accomodate .You must add a power amplifier so crackling will gone and to fit your listening pressure...

Hope it may help you;

If your battery has not got good power it will cut out on loud
or even if the car is running the alternator might be not putting the right charge out
also if it makes weird sounds like a squeeze sound or a cracking sound some thing is earthing out a termanal touching body? a speaker wire cracked or ripped?

Noise could be due to a bad ground and or signal interference ,Check the wiring and check if the ground is connected or maybe a ground lead came loose in your car .....

Check connecting the speakers by the battery manually out of the car and check.

Posted on Sep 21, 2008

  • masterexpert Sep 21, 2008

    you need to check that the output impedance of the stereo and the input impedance of the speakers match. For cars they are normally 6 ohms and they probably already match.

    The next thing you need to check is that the speakers can handle the 45 watt output of the stereo.

    If that's all okay then make sure you have decent wiring between amp and speakers.

    Just as an afterthought the vibrating could be because the speakers aren't in tight enough against the car door...

    thanks.
    feel free for further queries.

  • masterexpert Sep 21, 2008

    is your amp producing more watts than your speakers are rated to handle? are the speakers bolted down firmly and is the ground wire firmly screwed down and the connector firmly crimped to the wire?

I have an 1998 escort , i entered the radio code , the panel is lit and the search is working, although i raised the sound volume but no output sound , may i know why ???


Turn the VOLUME up to maximum.

Can you hear a noise?

YES?.....There is likely to be a problem with the radio

NO (Quiet) ...there is a problem between the radio and speakers ( loose connector , broken wire etc, blown speakers)

Car subwoofer just past half volume cuts off the amp


Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

well, the USB problem i cant help you with, but if the cd isnt loading, theres probably something wrong with the loading mechanism, which usually means that the unit is faulty. it would be more cost efficient to buy a new head unit than to pay someone for the parts and labor to repair the one you have.

12w3v2 Started making distorted bass noise at low volume


Connect each speaker coil one at a time to a square 9 volt battery and watch for the cone to move.

Also try hooking another speaker to your amp just to make sure the noise isn't in the amp.

You can use a 9 volt battery to test wire polarity also. Hook up the + wire of the speaker to the + terminal of the battery and the - speaker to the - battery terminal. If the speaker moved UP or OUT then the wiring is correct. If it moved IN or DOWN then the + and - wires are backwards on the speaker.

Also if you have two or more speakers hooked together test all the same way while they are hooked to each other. ALL of the speakers need to move in the same direction at the same time.

Clipping causes more speaker damage than anything. "Dirty Power" can happen in good quality amps too. The gain control is to match the voltage between the headunit and the amp. It is NOT a volume or boost knob. If you overdrive the first stage of the amp and then clip it damage will occur to the amp and speakers at some point.

Hope this helps.

New car speakers cut out when I turn up the volume.


You just have to check all of the speaker wiring.It's a wire touching somewhere and it will do that till you fix it. What it is is just where the negative wire which is the ground for your spreakers it's touching the positive wire which is know as a power wire.When this happends it lowers the frequency of the volume which will cause the speakers to cut out and volume level to drop.

Car Audio Cutting Out


stereo is detecting a short , or low load on speaker wire and or speakers .Go behind car stereo , disconnect all speakers and apply a known good speaker to one of four wires and see if volume works normally ..If it works use same speaker on all outputs one by one ..If all are okay then you should figure out what speaker and or wires are causing issue..Also make sure your ground is okay

HI BBunk,

Sounds like the dead speaker took out the amplifier output too. You may need a new head unit.
