Its a little difficult to understand your question. Would you care to rephrase it in English, and give a full account of your problem?

From what I understood, the man has installed a Chinese made car stereo that has the USB input, and the issue is that he hears the engine noise from the speakers.. (could be static)

If so by any chance, what a way to promote it, by saying it doesn't work laugh.gif

In case the OP has actually bought one and doesn't know much about car radios, @wbruwan - That isn't a car radio just like jdnet told you, even though the specifications you posted may tell you it suits cars, motorcycles and boats. I've never seen radios on bikes in SL and if it's got static, engine noise, interference etc. from the speakers, maybe when the you drive fast the road noise will be loud enough to make you not notice that laugh.gif

Boats, yeah sure...

Don't fall for Chinese marketing ploys and cheap goods..

Ok see if this works, will try keeping it simple :)

1. Remove car radio from car

2. Take it inside house

3. Get an AC/DC 12V adapter (like you fix to an electronic keyboard)

4. Fix to power input and turn on radio

5. Check if there is that 'noise' you got

So now, if you still get 'noise', something wrong with the cheap radio you got.

If you don't, try fixing to another car and see. How did you manage to power it up anyway? :)

cigarette lighter adapter :unsure: ?

BTW just to satisfy my curiosity I googled for motorcycle radios and found that they do exist (although couldn't find a 4 speaker version)!

maybe op will get better reception by using the mounting holes on the unit to mount it on the hood and take power directly from the battery.

Ruwan,

Pls answer these mate coz other wise i cant help u out.

Where have you taken your power from? Is it from the ignition or some other mean like power from the cigaratte lighter..etc?

Is ur vehicle diesel or petrol?

Also how old is ur vehicle. Has it got a ECU? (If u dont know.. tell me the make and the model of ur vehicle.)

Noise..

its not only alternator and spark noise, but often also EMR from the engine management system.

cheers..!

Okay... First check whether it's radio signal interference or power supply jitter creating the noise. Most probably it's the former, which you might be able to avoid if you fix the external antenna from your old radio to it.
