dustpuppy Posted April 8, 2010 Report Share Posted April 8, 2010 Hi guys, Upgrading my D3 for a Z110BT soon, but I'd like to sell my old unit first. Oddness that I had with this last install that I didn't have on my other vehicle: 1) I get alternator noise regardless unless I re-ground the RCAs, after that, no problem. I don't have a second amp to check with, but even the HU is grounded to the same position (hunting this and other issues brought me to doing a re-ground with distribution). That leads me to believe that something went wrong internally along the ways. Any idea if this will affect the powered outs, and/or how much it would cost to have an authorized center fix? 2) It's a strange thing, but when I turn off the car, I get a faint low-tone, then fades out (under 1 second) --- I'm wondering if this is something to do with my car's OE stereo having a 'cool fadeout' effect on turn-off. Anyone else experienced this? Would running a new 12V connection to the deck fix it? Being that the Z110BT is newer, I would imagine that pioneer has taken this into consideration by now if this is the case. Any constructive help would greatly be appreciated!

Proformance Posted February 12, 2011 Report Share Posted February 12, 2011 By running the extra ground is not going to affect the out put. It is the sAme as what's in the radio the resister inside is blown thus causing a whining noise. Quote Link to post Share on other sites
