I just got my new Bennington yesterday, I am noticing that the subwoofer is working, but doesn't produce a lot of base. I turned the sub volume all the way up, and its still lacking. I am guessing they do not adjust the gain on the amplifier at all when then install? I was going to adjust it, but when I looked at the amp, they installed it so those controls are under the helm, in towards the starboard wall of the boat. Kind of stupid because now I cant get to the adjustment knobs easily...going to have to un screw the amp from the sub box, flip it around and then reinstall it.
