Stern rail seats...
I bought a set that I am going to try to mount under the stern rail seats. I am going to use box types with a bracket mount and use quick disconnects so I can take them off when I leave the boat. Inside, I am going to get some flat mounted ones for the bulkhead. I am also going to mount the stereo in the port bulkhead that has the V-berth closet behind it. This way, I can use the wireless remote from the cockpit. I got a Jensen unit with a changer. Guess I will have build up a shelf in the closet to hold these, but it ought to wrok pretty well. 320 is just about the same set up as a 29.5/290 as I recall?
