I replaced mine on my 185. I used the Kicker marine speakers KM620 '09...the cutout was tiny bit bigger than needed but all mounting screws except for one worked. the one that didn't I just glued it in. The speakers are fine and work well. Hope this helps.
I have an 06 185 Sport that didn't come with the speakers in the front of the boat. How hard would it be to cut and add speakers in the location that they would have been and will I be able to wire them easily to the stereo? Thanks.
I am planning on adding 2 Infinity 6000 Tower Speakers, 2 Kicker KM620 speakers to replace the factory ones and 2 for up front...total 4. Diamond Audio 10 inch sub. What amps do it need to power all of this? I have heard kicker mx700.5, 450.2 are there any other suggestions?
