System Set Up Help

Hi everyone. It has been a long time since I have installed any car audio equipment other than a head unit replacement or speakers. I am installing (2) MM651 and (2) MM691 speakers in my boat (no subs). They are powered by a Polk D4000.4 4 channel amp. My questions are what would be the proper amp setup for this scenario. I was told that because these speakers have factory crossovers that I should set the amp to full range and simply adjust the gain. Is this correct? If not can anyone give me suggestions for the amp settings?
Thanks

    No. You want a low frequency cutoff for the woofer. The crossover will only filter where the tweeter and woofer overlap. 60 hz should be good but play around. Don't drop it less than 40, preferably 50.
