small class d sub

[jllogan]

I am going to add a 10 inch sub to my boat system. I currently have 4 speakers and a head unit and woul just lik ethe extra bump from the sub but dont need anything insanely big or loud. I also only have a 50 amp alternater so I cant get too carried away. So I was looking at some 300W class D amps when I saw this

Do you think its too small or a mistake? I like the idea that I can use a small gauge wire for power supply and I doubt it would have a very high amp draw. Also Its small enogh to be mounted discretely. What do you guys think?

I would find a sub first and then see what it needs to drive it.
