Car Power Filter EMI Noise Ground Loop Isolator Suppressor for Auto Stereo Audio Radio Stereos Amplifier Amp Speaker Equalizer Subwoofer 12V

Ha solucionado bastante bastante ruido, también creo que no lo ha conseguido del todo por culpa de la radio android.

Netjes verpakt en snel geleverd- product komt overeen met beschrijving en foto- kwaliteit

Ottimo ha funzionato egregiamente dove l'alternatore faceva un fischio tipo UFO ;-)

Il est très bien mais attention le fil d'alimentation est assez gros, prévu pour un ampli, mais pas pour un autoradio, mais fonctionne parfaitement

Firstly, I must point out that I am not an audio technician. I'm just somebody who enjoys having a go at upgrading cars I own as much as possible. Having purchased a BMW e91 Touring M-Sport recently, I also purchased a replacement Android stereo to allow me to have DAB+, Google Maps, hands free calls etc. etc. Fitting the stereo was much easier than in previous cars, the (CANbus compatible) wiring was pre-configured to allow the steering wheel controls to work out of the box; not something I've come across with previous Japanese cars (Lexus and Toyota). Having fitted the stereo, everything worked as expected. However, I had lots of noise/interference through the speakers. Both DAB+ and FM as well as with nothing playing. It was a mixture of a high pitched tone that changed when accelerating and a lower pitched 'crackle' type of sound. Research suggested numerous potential causes, but most people pointed to alternator whine/ground issues as the culprit. Anyway, fitting this box (which was very easy for someone with a little bit of knowledge about wiring) has resolved the issue entirely. All the unwanted noise has gone...nothing. No interference, crackle, whine, high pitched tone or anything other than whatever I'm playing on the radio! Perfect. I'm so pleased, this product exceeded my expectations!
