spursmaddave Posted August 6, 2014 Share Posted August 6, 2014 Take it back, get them to sort it. That's why I was asking about the amp but even then noise like this is normally wiring or earthing related Quote Link to comment Share on other sites More sharing options...
Angrybiker Posted August 6, 2014 Share Posted August 6, 2014 No just the head unit and steering controls, still running the existing Bose amp, speakers and wiring Quote Link to comment Share on other sites More sharing options...

BulletMagnet Posted August 6, 2014 Share Posted August 6, 2014 Tell them you can't just earth it to the bulkhead, you need to earth it through the wiring harness too Quote Link to comment Share on other sites More sharing options...
Angrybiker Posted August 6, 2014 Share Posted August 6, 2014 I was there when they re-earthed it, tee'd into a cluster of earth wires that connected to the bulkhead, I'd have thought that the wiring harnesses would eventually feed back to there. Why do u need to earth it through both? Quote Link to comment Share on other sites More sharing options...

Why do u need to earth it through both? A Zed is a bitch to earth, mine had terrible alternator whine until I earthed it to both, don't have it anymore or I would take pics to show you where, sorry.... I found it also helped getting an engine earthing kit, they are cheap help with this and also you get a smoother idle too Edited August 7, 2014 by spursmaddave Quote Link to comment Share on other sites More sharing options...
Angrybiker Posted August 7, 2014 Share Posted August 7, 2014 Aww right. Cheers, I'll give it a look Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted August 7, 2014 Share Posted August 7, 2014 Just a thought but do you have to have the stereo up very loud or did they fit a line booster? The Zed amps are a very high frequency so an aftermarket HU can sometimes be very quiet. Have a search for. Busters RCA hack for an idea, that may also help Quote Link to comment Share on other sites More sharing options...
Stutopia Posted August 7, 2014 Share Posted August 7, 2014 Only just seen this, feel your pain mate. My Pioneer install by a pro was good, slight issue with the balance being the wrong way round, but they sorted that. After I fitted a reverse cam I ran the cabling past the my new amp (in the OEM space) and along the passenger door trim and round the footwell to the HU. Suffered from alternator whine immediately. After some trim removal and taping wires as far apart from each other as possible and earthing to a bolt somewhere else in the boot it just went away. If it's not the earth, which it probably is, it could be cross talk from another wire if the wiring has been done too or even behind the HU. Wish I'd known to try earthing it somewhere else to begin with, no one thing seemed to cure mine, just persistent tinkering. I'm hoping it doesn't come back in the winter when she sits at a higher RPM idle, once I'm going the exhaust hides a multitude of squeaks, whines and rattles. As for getting the centre console back in snuggly, mine was a real PITA this weekend when I changed the iPhone cabling. There's a bird's nest back there and it just wouldn't cram in. In the end I cable tied some of the bigger lumps out the way behind the plastic bits which are behind the HU (wish I'd taken a pic now) and shoved some boxes off to the side, just fitted back in after that. I'm loathe to take it out ever again! Quote Link to comment Share on other sites More sharing options...

Tell me about it, I fitted a satnav in behind there and an extra speaker too, oh and a digital radio box and all the wiring, oh and a tmc aerial for the satnav..... Oh and the wiring for the electric cubby door and switches etc.... Mind you it was impressive when it was all done if I do say so myself 1 Quote Link to comment Share on other sites More sharing options...
