Advice needed or if in Melb and can can help me il pay you. Buzzing noise

[Homer's HSV]

I have a 2011 R8 stock head unit Amp is is Genesis Profile 4 Front Speakers Morel Dotech Ovation 6 and Rears are Alpine SPR-60. No Subs
The system sounds great i have no issues with the quality but when my volume is low say 1-5 i get a slight buzzing noise coming through the speakers my Amp is grounded well and it didnt make this sound with my stock system its just annoying when i have ppl in the car and the radio is turned down low its a constant noise not like it whinning up and down. As Mentioned iam in Melb if anyone can help me to fix this issue i will pay you. Dont know too much about car systems so any advice as well would be great. Also i have been told the wiring is opposite to the power cables and so forth.
Cheers Eddie

It would be alternator whine.

Is there anything i can do about it i bought a noise suppressor (I think thats what is was called) from Jaycar was cheap but didnt make a difference got an auto elec to put it on.

If you're using a LOC it could that. Where is you're remote wire connected?

How did you connect the head unit to the amp??

I didnt do it audio place did but they told me that it is normal which i cant understand my amp is in the boot though sorry man if i sound dumb on this

That's alright mate. LOC is short for Line Output Converter. The LOC is a little device that splices into original speaker wires and gives you RCA's to connect to the amp. Do you know where the remote wire is connected? It's usually a blue wire coming from the amp.

The blue thin wire is connected to the amp but cant see where it is going the other thick blue wire is to the fuse near the battery
