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.

 

Any big company would advertise that amp as a 420 watt amp, or whatever the very max output is.

And to what those numbers mean:

150 watts x 2 @ 4 ohms stereo

150= watts
x2= per each of the 2 channels
@ 4OHMs= when the amp sees a resistance of 4 OHM.

*Power output varies from the number of OHMs. That is dictated by the specific sub you use and how you wire the voicecoils.

 

Got it. thanks
