[QUOTE="treesive, post: 8214323, member: 631309"] I have used some of the best class a/b,d,and g/h amps on the market. After saying that I do not run class d on my high's. This might not be so much the class d amps but they obviously have something different that makes them more prone to noise, whine, etc. I had the same problems with my hd600/4, hifi 6150, and the PPI900/4 which was the noticeable alt whine coming through the speakers. This to me since I am more SQ geared is a pure no no. At first I thought it was the legendary pico in my headunit even though I did the rca ground etc to the head when I bought it. I was pretty much set on breaking it open to solder over it when I was in the process of changing my amps out. I put my se4200 back in (class g/h) instead of my hd and took it around the block a couple times to determine if I liked where my settings were. It caught me off guard when I noticed zero whine from the speakers. I tried it again with my usa-442, zapco z150.4, and my honey elite.4. None of them sent that whine through to the speakers. Now I don't know enough about the inner workings of amps but something with my systems setup will not allow me to run full range class d. Sound wise I do think that class d is getting close enough by the quality brands to not be noticeably worse in sound than other classes. I just figured that it was important to tell you this story as something in the design differences allows this to happen in my setup. [/QUOTE]
