wizzardeel Posted December 29, 2008 Report Share Posted December 29, 2008 Ok so I just got my F90 installed in my car today and whenever it is turned on and nothing is playing or the volume is down there's this background noise that is in the speakers kinda like when you dont get a station on radio and its just that searching stations noise. is this happening to me because poor installation or one of the cables is not properly plugged in or is this happening to everybody else?

terron Posted December 29, 2008 Report Share Posted December 29, 2008 need more information does the noise happen only when the engine is on or both when it is off and on? what kind of car is it? are you using a factory or aftermarket speaker amp or is the AVIC powering the speakers itself?

dianebrat Posted December 29, 2008 Report Share Posted December 29, 2008 terron pegged it, There are so many questions, I'd ask my installer about it, they're supposed to make sure that things are grounded, line levels are set right, units are properly matched to any amplifiers already in the car, etc. But to answer the basic question, no, the units do not have any inherent background hiss that I've heard.

I fixed it by turning down the sound effects level in the NAV menu to a very low setting. Quote Link to post Share on other sites
wizzardeel Posted December 30, 2008 Author Report Share Posted December 30, 2008 pretty much as soon as the pioneer powers up after like 30 seconds when the ipod starts to play if i turn the volume down to 0 theres this hissing noise so ill probably go back to the place i got it done at and let them know about the situation. im driving a 08 civic si and its using the stock amp Quote Link to post Share on other sites
flyboyindy Posted January 2, 2009 Report Share Posted January 2, 2009 Ive got the same noise you are talking about. Its not really hissing...but when the volume is low, it is very noticable. Sometimes it gets louder depending on the function of the head unit. I thought it might have been the combination of the head unit with the Metra adapter in my RX-8. It really has nothing to do with alternator whine or anything like that...just kind of annoying. Quote Link to post Share on other sites
mazumder Posted January 3, 2009 Report Share Posted January 3, 2009 I had the same issue. Apparently, it is because the voltage of the speaker output from the AVIC is sometimes a little too high for the stock amp, while the pre-amp out is a little too low. My installer eventually installed the SVEN4 in-line converter from Peripheral, and the problem is entirely resolved. Quote Link to post Share on other sites
wizzardeel Posted January 6, 2009 Author Report Share Posted January 6, 2009 ok so pretty much my installer told me the same thing what flyboyindy said and he said that in order to get rid of that i would have to get an aftermarket amp. can you mazumder let me know where you got that SVEN4 in-line converter. I went on peripheral electronics' website and they dont have the sven4 for a 08 civic si. if you can find one from a different manufacturer would you mind giving me the website or at least tell me the part number. it would be greatly appreciated. that noise is really annoying and i was also trying to keep my sound system stock even though i already have an amp and subwoofers. thanks Quote Link to post Share on other sites

wizzardeel Posted January 6, 2009 Author Report Share Posted January 6, 2009 ok so pretty much my installer said that im getting that noise because i am receiving feedback from the factory amp. so you said that if im getting this harness this noise will be gone? i just want to be 110% sure so i dont throw my money out the window Quote Link to post Share on other sites

The Vibe forum I linked you to gets the question a lot because they have a decent factory OEM amplified Monsoon audio system with 2 ohm speakers, and the amp there needs input that's higher then the RCA jacks, but not "high output speaker output" like you'd find in a unit like the Pioneer, in other words, when Pioneer claims 50W speaker output, that's more then the factory amp wants. My Vibe never needed the Scosche converter when I had a JVC head unit, it was fine, but when I had the AVIC installed with a friend, we knew the hiss was the AVIC needing the output lowered, but that was a risk we talked about taking only because the JVC never did it, in other words we got lucky. So I have the AVIC, then the FAI-3 on the speaker lines that feed into the factory amplifier. It's something that we as lowly consumers were willing to risk because it was easier, but it's something a professional installer should never have done, a pro would, and SHOULD know better. The Scosche FAI-3 is nothing special, and I'm sure the SVEN4 is similar, but better built, the FAI-3 is $20 at Walmart, after all, you have to strip the wires and just clamp them in the FAI-3, the SVEN does all that for you in a nice "everyone has the correct connector, no one has to cut or solder anything" package but it does the job when you're in a pinch, and it's the favorite way to convert high power speaker outputs to the factory amps over in the Vibe DIY crew, and I listen to them, they've not steered me wrong.

wizzardeel Posted January 7, 2009 Author Report Share Posted January 7, 2009 ok so i have the 08 civic si and it has the factory amplifier and amp and my installer hooked up the f90bt and it has that hissing sound. what exactly do i need to make it stop? cheapest and easiest way. thanks p.s. ill go tomorrow to a different audio shop and ask them if they know how to solve this problem Quote Link to post Share on other sites
