[QUOTE="Chromatic, post: 8214444, member: 659121"] Thanks treesive for your story. I was all set to order the class D 4 channel amp tomorrow,.. now it's a little concerning that you say you get noise/whine from them. I'm going to have to go with the rest of the people who use them, and tend to think it was an issue with your particular setup somewhere. If decent class D amps all tended to have noise/whine the reviews on them would be horrible. Thanks for the heads up,.. and if I end up with a noise problem I can come back and tell you that you told me so! [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] But, with the space I'm working with.. putting the amp in a closed non ventilated area.. A 4-channel class D amp is the only thing that makes sense for my application now. A/B barely fits (some don't).. and they will run hotter,.. and adjusting them once mounted would be next to impossible. So I'm going to have to take the chance. I'm either going with the Kenwood eXcelon 120x4, or the PPI 900.4 (I think it's called) which is about the same.. a little more powerful at 14.4v. Both good brands,.. I don't think either have the "bass knob" that I'd like to have to mount by the parking brake in an empty switch slot to adjust on the fly.. but that's life. This a typical widespread issue you guys with say a PPI Class D amp? That I will probably get noise/whine using it? I'm not doubting you at all treesive,.. I totally believe you got whine in your setup with multiple non A/B amps -- and something about the A/B design kept that from occurring. Thanks [/QUOTE]
