Truffles Posted December 4, 2007 Report Share Posted December 4, 2007 I have two things going on that I'm going to have the installer check for me. I was just wondering if anyone else has experienced it. I replaced my stock JBL radio in my 2006 Solara convertible with the AVIC-D3. (XM and BT as well) I'm getting what I think they refer to as alternator whine. A high pitch noise that increases as I press down on my gas peddle. I also don't get much volume out of my rear speakers. I have the factory installed speakers with nothing additional added. When I change my balance to just the rear.. it doesn't sound anywhere as vibrant as when I have it to the front. Quote Link to post Share on other sites
HiFiSi Posted December 5, 2007 Report Share Posted December 5, 2007 Maybe your rear speakers run through a factory amplifier which they forgot to hook up? Or maybe they're of a higher impedance that the front speakers. As for the whine, if everything is factory but the unit, I'd say check your grounds. And even ground the unit to the chassis of the car rather than through the car's radio harness. Quote Link to post Share on other sites
subaru_terrence Posted December 5, 2007 Report Share Posted December 5, 2007 I have alternator whine in my 02 subaru legacy as well. The installation was done by some audio shop so I dont know too much about grounding and stuff. However, I am pretty sure the guy didnt ground anything to the chassis. If I want to ground it to the chassis, what do I have to do? Quote Link to post Share on other sites
HiFiSi Posted December 5, 2007 Report Share Posted December 5, 2007 Find the black wire coming out of the D3, clip it from the car's stereo harness, and screw or bolt it to the body of the car. You can use a pre-existing bolt if there's one in the area. Quote Link to post Share on other sites
Truffles Posted December 7, 2007 Author Report Share Posted December 7, 2007 ok.. got the whine taken care of. The installer added some noise suppressors.. My front to rear fader still seems off... I can't have it centered.. I have to have the fader 2 notches to the front for the sound to be acceptable. I'll play around with the setting to see how to make it sound as good as possible.

Dabigcheezze Posted December 7, 2007 Report Share Posted December 7, 2007 So you put a bandaid on it? Ya know it's still bleeding right? Quote Link to post Share on other sites
DJ Hellfire Posted December 7, 2007 Report Share Posted December 7, 2007 My front to rear fader still seems off... I can't have it centered.. I have to have the fader 2 notches to the front for the sound to be acceptable. That may just be due to your height and seating position. For example, if you slide your seat back, your current setting will sound like it's off even though you just moved the fader 2 notches to the front. Also, if you have your interior speakers on an aftermarket high power amp, make sure the front and rear gains are equal or at least sound equal from your seating position.

Truffles Posted December 7, 2007 Author Report Share Posted December 7, 2007 I guess I don't know much about the set up.. Even though I don't have a subwoofer.. I went in to the initial settings and selected Sub W for rear speakers and it sounds much, much better. I have a Solara convertible and not sure if the rear speakers are meant for bass only or not.

Truffles Posted December 7, 2007 Author Report Share Posted December 7, 2007 So you put a bandaid on it? Ya know it's still bleeding right? Obviously not.. I guess trusting the installer was a mistake. I went to a local reputable dealer and avoided the big chain stores because I thought I'd get a better install. Quote Link to post Share on other sites
jatolbert Posted February 7, 2011 Report Share Posted February 7, 2011 ok.. got the whine taken care of. The installer added some noise suppressors.. My front to rear fader still seems off... I can't have it centered.. I have to have the fader 2 notches to the front for the sound to be acceptable. I'll play around with the setting to see how to make it sound as good as possible. What was the solution?? I have the same problem. High pitched whine that increases with pedal position on my D3. Josh Quote Link to post Share on other sites
mdman Posted May 16, 2011 Report Share Posted May 16, 2011 Where can I get the noise suppresserse from and where do they go on the d 3?? Quote Link to post Share on other sites
chawski Posted August 21, 2011 Report Share Posted August 21, 2011 are you running an amp that is connected through the rca's in the back? Its my understanding that the rca's are grounded through a "pico fuse" which commonly blow. I had a similar problem and remedied it by just not using my 4 channel amp and running my front components and rear 6.5s off the headunit, and subwoofer though the amp. Its not that difficult to fix if you have some experience in soldering and electrical work, but keep in mind that if you send it back to pioneer to fix, its a $200 flat rate fee for a 20 minute repair Quote Link to post Share on other sites
