i was messing around with some of my amps and i noticed that i really dont like the way class d amps sound. i ended up disconnecting all my speakers except my subs and listened to it and noticed on songs that i know the bass is 1 simple square wave it sounded like 2 oscillators with one oscillator going in and out of tune with the other. this didnt happen with any of the ab amps i tried it with everything sounded tighter more in control. maybe its just these class d amps im using they are cheap or maybe the eq phase gain or subsonic filter was set wrong every single time i adjusted them or the lower damping factor class d amps have. idk but it annoys me

Come on guys ... he's from Alaska ... They're thin on oxygen up there.
I'm just messing around Alaska guy. I love Alaska. I flew up there for a week once when I thought I was going to be moving there. It was awesome. I'd take Alaska over DC any day.

i can definitely hear the difference. i made sure all the settings were the same on the ab and d amps. im pretty sure its the lower damping factor of class d amps

what you're hearing is distortion caused by something such as the gain being set too high or just a cheap amplifier with a poor quality power supply.
It's not the amplifier topography that's causing the audible distortion though.

that could be your problem setting 2 diffrent amps with the same settings doesnt mean there gonna produce the exact same sound. u need to make sure that your amps are set properly to the amps not to another amp.
