rossselsby Posted November 11, 2009 Share Posted November 11, 2009 my stereo speakers are currently whistling when I'm driving along listening to music. Soon as I turn the stereo off, the whistling goes. My stereo has been wired up weirdly, for some reason the sub is running off the battery as normal but then the power is going from the battery, to the sub, then to the stereo. Any thoughts?.....?Cheers, Link to comment Share on other sites More sharing options...
vti_aerodeck Posted November 11, 2009 Share Posted November 11, 2009 If my understanding is correct Its not your speakers that are whistling its your sub! I have got the same problem atm in my MC2, im experimenting with a few things and I will let you know!A good way to be sure wether its your speakers or your sub thats whistling is that Unplug your remote wire from the back of the sub/amp i.e. Turning off the sub+amp completely and then go for a quick test drive...Obviously if you still hear whistling from your speakers then you know for definate its your speakers but if you dont then as I said it may well be your sub!Try doing what I said and keep us posted! As I said i am in the process of figuring things out in my car once I find a strong solution I shall update!Good Luck! Link to comment Share on other sites More sharing options...
jalesi2001 Posted November 11, 2009 Share Posted November 11, 2009 It sounds like you have a bad earth, or you have your power lead to your sub running along the same area as your speaker wires. You can get supressors, or the best thing to do it run your speaker wire down one side of the car, and your power and trigger/remote wire down the otherside....a pain in the bum, but that should fix it. Like vti-aerodeck says, keep us posted on your findings!! Link to comment Share on other sites More sharing options...
Moe Posted November 13, 2009 Share Posted November 13, 2009 are you running a pioneer headunit by any chance? Link to comment Share on other sites More sharing options...
rossselsby Posted November 16, 2009 Author Share Posted November 16, 2009 No not running a pioneer head unit. Got one of them all in one units, gps, card reader, tv etc etc, however the cowboys that put it in cut all the wires at the back, the wires to the AUX, to the GPS, to any tv's you might put on the head rests for passengers in the back seat, the tv ariel wire etc etc. The systems seems to run from the battery to the sub, then from the sub to the stereo, isn't that arse backwards???It is defo the sub though, been out for test drive with sub off and no whistling. What's weird though is that the whistling goes up as the revs go up. Thanks for info guys!Ross Link to comment Share on other sites More sharing options...
-AL- Posted November 16, 2009 Share Posted November 16, 2009 Ive had this problem before in the birds car. And stopped when I went fromn running 2 amps to just 1 bigger one. People always told me was a bad earth tho. Link to comment Share on other sites More sharing options...
rossselsby Posted November 16, 2009 Author Share Posted November 16, 2009 Well i've swapped my sub over to a fli one now, and it's still doing it. I think it's due to wiring as the stereo is proper messed up it seems. Ill check to see how many amps it's running and maybe that cud solve it, cheers al!

Moe Posted November 19, 2009 Share Posted November 19, 2009 take the earth off, sand it down to bare metal then try again. if the whistling is still there then you might have an earth track fault in your system. to check that connect an earth from your headunit to the outer part of the phono plug that goes to the amp Link to comment Share on other sites More sharing options...

What's weird though is that the whistling goes up as the revs go up. RossThats because, As your alternator spins to generate charge capacity for the battery, it is causing resistance and as a result a WHINE in the subwoofer, (please correct me if I am wrong anyone!)As I had said I was in the process of trying a few thing... well heres a quick solution that you can try...http://www.halfords.com/webapp/wcs/stor ... yId_165626Its got a good wiring diagram on the packaging and should be pretty straightforward to install!Good Luck & Keep us posted!

jalesi2001 Posted November 21, 2009 Share Posted November 21, 2009 Yeah, thats the suppressor thingy i was on about, they are ok, but in my experience they never completely fix the problem..... Link to comment Share on other sites More sharing options...
