Amp making noise?

[Anonymous 10+ year member]

I have a Hifonics BXI2607 that makes a strange like buzzing from the RCAs when I play a certain note. I know the noise is coming from the RCAs because when i disconnect them from the amp the noise goes away. It only makes the sound on one note the "This is Why I'm Hot" High note. It does not make noise on any other song or anything but what can I do to stop this noise?

Ground your RCAs to the back of your Headunit. ....

Is it anything that is harmful because the amp seems to work well.

you sure it's not just a distortion in the version of the song your playing? or is it happening via an FM radio station?

if its from a burnt cd i wouldn't be surprised if it was just a bad file

Other than that, if it doesn't happen except in 1 note in 1 song I wouldn't worry to much

it is a burnt cd downloaded to my usb flash drive. It is actually Lil Wayne's remix.

Actually I was listening to my system earlier and I noticed that the amp was making the noise on different songs and different notes, all of them were high notes. I also noticed that the noise did not occur until I turned the volume up to 20/35 on the HU. And the noise gets louder the louder I turn it up. I do not believe it is the HU because I have 2 of these amps and the amp that I have the RCAs from the HU ran to does not make the noise, it is the second amp that I used a jumper RCA to hook up. I changed out the RCAs and it still makes the noise. Could the amp be faulty? Could I have my gains too high, I set it with a DMM. Other than that noise the amp works fine, it pushes out plenty of power and does not even get warm. What could it be and could it be harmful to my amp? It only does it on notes that do not hit hard, that is how I noticed it, at first I thought it was just another rattle until I put my ear to the amps RCAs and heard the buzzing noise everytime the bass hit. Pounding bass such as Jeezy and Lil' Jon the amp does not make a noise. Other than that I can not find anything wrong with it. Even though it makes that noise the amp is still perfectly functional and pushes the power it is supposed to, I am just mainly concerned what could be causing this noise and whether it is or could possibly damage or be harmful to my amp. Help if you can any feedback is appreciated.

If your amp has a crossover make sure it is set right, it could cause the buzzing noise which would come through your speakers.
