feedback loop You can try making sure your power wires and audio wires are away from each other, abd you can also buy suppressors for it too Some original photos have not been recovered yet.

simple tricks as platinum said is to have the power cable on one side of car(door sills) and speakerwire and remote wire etc on other side. bit of messin round but helps , also get quality high supression leads etc in engine , and tape up and even wrap the plastic conduit tubing around all wires in engine bay.

Ah the old "move the power wire trick". This won't help as the body off the car is also a conductor so moving the pwer cable to the other side is pointless. By the sounds of the problem it has only just started? If so check to make sure the ground connections to the battery, chassis , and engine are ok, failing that check the rca connectors if you are using an amp as they can break inside and cause this trouble. See how you go ...

thanks for the info guys, I'll play around with it tomorrow. it is to cold at the moment to go out side and even into the garage I'll post a reply to tell you what the problem is!

With some h/u you put them on am, and play with the stations and u will notice signals change to a higher pitch as you accelerate, kinda cool for about 10 seconds though...

na bud it is your amp same thing happened to didn't know what it was 3 hours after installing it did the same the high pitched whissle squalling it like a diode or somthing which has blown in side - if you have still ago your recept take it back tell em they shoule replace it no worries, like thay did to me -

this system had no amp

hmm might be your head unit then !! Some original photos have not been recovered yet.

Try running the Stereo with the Engine off, if it doesn't make any noise then you're getting Power Line Noise interference from your Alternator or something similar in the electrical system, if it is that, then you can buy a Noise Supressor from JayCar or someone like that... Also, try turning your Lights on and off (Even High Beams) and the Windscreen Wipers, if it makes a 'Clicking' noise, then a Supressor will fix the problem... 8) Some original photos have not been recovered yet.
