Speakers all fit well in standard cut out in my pontoon. I have a modest 1000w Vibe amp and peep Boss marine review deck pushing them. I figure rms to these from the Vibe is most likely around 200w each. They sound marvelous! I ran all overwhelming measure power, ground, and speaker wire. Most likely insufficient amp for them but rather this was an ease framework for a pontoon that I just use around 10 times each year. They don't mutilate until around 75% volume which you can get notification from 75 yards away simple. Considering they have such substantial magnets I figure they could deal with twice as much power.
