Buzzing/Hissing Rear Speakers.
Ok so im back again haha.
On my way back from my weekend away (which was sh*te, dont ever go away with the other half's parent's :keule: haha) i noticed the rear speakers began to make a high pitched buzzing/hissing noise, turned the volume down and it was still there, pressed the mode button to change over to a cd and it made a high pitched noise, cant describe it, thrn it carried on with the buzzing etc. Turned the HU off and back on, was still there, then after a few minutes it went, 15 min's later it was back and so on.
Any idea's guys, running the standard HU, havent touched anything etc either, just found it so weird.
