You are welcome to believe whatever you like, but my signature says it all. I was extremely skeptical myself until I bought one of them and now I can't say enough good things about them. Then again in reading your signature as opposed to mine, we are definitely not into the same thing. I am in car audio to get loud, your signature indicates you like to actually listen to music so I don't think Power Acoustik would suit your tastes. I guarantee you this much, if your electrical system is supplying proper voltage to a A3000Db you will be very close to 3000 watts.
