[QUOTE="Anonymous, post: 3576401, member: 558845"] 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.
