Head Unit change in 3200 whine now from speakers :-(

Hi

I changed the headunit in my 3200 last year. Now I don't really listen to it very often as I prefer to
listen to the exhaust note :) but I am doing a 4 to 6 day tour around Scotland end of next week and it would
be nice to have some tunes on the motorway sections.

I have the auditorium with factory amp in the boot.

I have now fitted a Pioneer High Volt output headunit with Handsfree for my Phone.

The problem I am getting is a wine matching revs occasionally. I believe it is because the head unit is sending a high level
output to the amp, which takes its feed from the speaker output from the head unit and not a phono output/input to the amp,#as the factory amp I believe does not have a phono input.

Has anyone else fitted a new headunit and experienced this and managed to cure it?

When I speak to my local car stereo guy he draws large chunks of breath saying it is a tricky one to solve.

What I appear to need is an Iso to Iso adaptor that drops the high level output to a low level so my amp isn't getting sent too high a signal

Hope that makes sense and any help would be great

Lee

It's the high gain amplifying the noise from the alternator best bet is to replace the amp and run RCA cables (phono).

Thanks Almichie

That has been suggested, I was just trying to see if there was a high to low cable/adaptor available to drop the power going from the head unit to the amp.

The OEM amp using speaker inputs is a bit 'cheap' IMHO!
Surely if you lower the speaker feed input to the amp, you will just lower the volume level?
Only way is replacing the amp and using the phono output of your new head unit to the new amp I think.

The OEM amp will be cr@p. You can buy a decent replacement for not very much money which will have all the connections you need for your new head unit and will make everything sound better. The whole sound/system in your car is only as good as the poorest component. An ancient amp built to a budget and the terrible standard fit speakers should be first on your list to change if you want to improve the sound.

I've just read the title of this thread again - you're getting wine from your speakers? How is this a problem? Spilling when you go round corners?? ;) ;) ;)

Now if it where that sort of "wine" from my speakers and not a "whine" then I would not be complaining :)

And now realised I made a spelling mistake and I hate it when I see mistakes in things like people's E Bay adverts and now I'm doing it...

Have you tried using a screen twisted pair cable for each speaker feed between the head unit and the amp? This might reduce the noise a bit? perhaps reduce the wine from a full carafe to a half carafe? :)

I would prefer a full carafe if I'm honest ;-)

I, myself, am perfectly capable of reducing a full carafe to a half carafe with very little effort, and only get twisted up when nearly all the wine has gone.
