I have 07 fourwinns 210ss. Finally got the stereo how I want it. Local stereo shop built me a custom box that goes under my rear bench seat that fires 2 Sundown SA-12's up and ports out, powered by Kicker zx1500. I have 8 exile sx65m cabin speakers on a Sundown SAX 100.4. Love the way it sounds in the boat. Here is a short crappy cell phone video volume is about 1/4 up at the begining then I turn it up to a little under 3/4 which the cell phone mic sucks.
