Hey,
I'm trying to pick up an amp. I fine with everything under the hood, but I don't know sh*t about car audio. So if you guys could tell me what this means,
or tell me the location of a n00b-education site where I could find this for myself, I would be most appreciative.

150 watts x 2 @ 4 ohms stereo
210 watts x 2 @ 2 ohms stereo
420 watts x 1 @ 4 ohms mono

I'm guessing that it has at most 2 channels and the power output varies depending on how many channels are used. Would this be advertised as a 420 watt amp? Or am I stupid.

Thanks.
