TURN OFF NOISE

It works for few month with no problem. Now each time I turn off the radio or the car a big boom noise comes out the subwoofer. The subwoofer sound is OK.

    I double check the positive cable that runs from the battery to the subwoofer and the ground cable. Install a new battery and teminals too, just in case.

Hi,

This sounds like a small line capacitor discharging and amplified by the power amp. Unfortunately, this small capacitor can be anywhere from the head unit, equalizer or electronic crossovers (if any), regular amp (if separate from the subamp) and where the RCA terminated cables from the HU initially goes to and finally the sub amp itself. These could be a 1~2.2uF (or thereabouts) line/series capacitor. Its purpose is to provide a pathway for the audio but block an DC signals. What you are hearing (I suspect) as boom are these capacitors discharging along the audio line.

Corrective measure would be open the units up, performing diagnostic and capacitor test (specifically those that are used as inputs). The best would be with the use of a capacitance meter but an ordinary analog VOM/Continuity tester would also do the job. These capacitors are normally located pretty near the RCA input or output jacks. It is not uncommon also for capacitors in the amplifier to cause similar concerns.

Alternately, a quick and dirty trick to reduce if not eliminate the sound is to install another set of capacitors along the audio line. This could be done at the HU's RCA output or the amp's RCA input. Of course this did not correct the defective capacitors (if any) but merely a workaround.

Another possibility that can not be discounted is that the internal DC to DC power supply of the sub amp is acting. Again main possible culprit could be the big capacitors. Additionally, it could be simply the speaker relays (if present) failing to switch off during power down.

All of the above of course would require that you be familiar with electronic circuitry and components, the use of a DVM and possibly a soldering iron. Should you be uncomfortable with a DIY, perhaps your best bet would be to seek the services of a qualified audio professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

When i turn da radio off then turn the beat on it work n stop


I don't know if your talking about subwoofer or speakers but if they stop while a big loud beat comes in its to much for your amps if you have them to handle and the amps turn of and by turning of your head unit and on again it resets them and works again try turning your gain down on the amps

You need a noise suppressor put on the radio power lead to kill the static. You can get it at radio shack.

I just bought a eonon e0821 and when I turn on my truck you can here engine noise but when the truck is off its gone


The engine noise is there because of the way you have your power cable ran and the ground cable grounded. When grounding your DVD player, you want to ground it to the good ground (bare metal of the chasis) or a cable directly to the ground on the battery. One way to do this is to remove a bolt from your seat, place the connector underneath (make sure the connector is big enough for the bolt to go through) then bolt your seat back down. This will be more than sufficient for the grounding needs. Now the power cable needs to be a certain gauge, and not cross over any speaker cables. This should solve your problem. If this doesn't then radio shack sells a device to cut down or eleminate the engine noise. I hope this helps.

Popping noise on my 12" type r subs


The subs are making that sound when the bottom out + when they reach full excursion be careful if it keeps happening eventually your subs will fail because you will end up damaging the subs voice coil.

Radio sound with a noise


Please take out the speaker and inspect it for a torn cone. At times, humidity, amp power or just wear and tear ruins the cone. Then you can replace the speaker or re surface the old speaker with a new cone. That will save you some bucks but may not be as well as buying another speaker. Also please use the same model and Ohms of it. 8 or 16 ohms

High pitched noise comin from sub


if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.
