Deep cycle battery for running stereo etc

[KVF 700]

Looking for a deep cycle battery to run the stereo on my old boat. Wondering what I should be keeping an eye out for, when comparing different models. Obviously the cranking amps won't matter since it will only be used for stereo, fish finder, bilge. My plan is to have it fully charged and then use it all day on the boat for the stereo(possibly might run one sub and amp as well). Maybe thinking of getting a small (5 watt) solar panel to help maintain the charge. Maybe this will not be necessary. Will charge it in evenings with battery charger at camp.

Let me know your thoughts and experience. So far only looked at nautilus batteries from c tire.
