I have three of them in my 210. I would day it is a perfect amp for those speakers. And it is made specifically for boats.
One is powering the four factory rear Polk speakers. One channel for each of the four speakers.
Another powers the two factory bow Polks with two of the channels. The other two channels are bridged for the factory Polk subwoofer.
The last one is in bridged, 2 channel mode powering the Skylon Rubicon 250's on the tower.
Not the best system you can put in a boat but considering I didn't alter the factory system too much, nor did I spend too much additional money I am very happy with it.
