    Hi Guys...

    Having real trouble with Interference on my standard head unit in my S4... it started out okay, but certain amp would not work (mono blocks), now my standard amp is starting to suffer the same - int comes mostly from the engine/alternator. I have run a second earth to the back of the head unit... if anything it seems to have got worse, so I am at a loss as to what to do.

    A: Does anyone have a concert (single din facelift) head unit I can try/buy? I would rather keep it stock... if I have to get an aftermarket HU - what is best... ideally want to connect to my iPhone also BT Hands free built in be a nice touch.

    You need to use a ground loop isolator on the RCA's going to your amp, as I'm guessing if you disconnect the RCA's from the amp the interference stops?
