2 questions please!

The Rockford Fosgate 25 to Life Punch 150 is only 2 ohm stereo stable or 4 ohm mono stable. If you want to come up with your 4 ohm mono power rating, look at the 2 ohm all channels rating on the birth sheet and that is roughly your four ohm mono power.

For example, the amplifier above will deliver 501.5 watts per channel @ 2 ohms stereo or 1003 watts @ 4 ohms mono according to Rockford Fosgate's measurements.

 
Another word of caution... Some of the later model Honda vehicles perform equalization in the factory head unit. I know my 2007 Accord did and it made for a weird sounding add-on subwoofer.
