For just 2 batteries and have power the most popular charger will probably be a ProMariner 20 amp dual bank charger. I haven't seen a reasonable solar charger with more that 1.25A and that's not nearly enough to desulfate a drained battery. However, doesn't sound like you guys drain the batteries if use multiple times per day several days per week. Guess it depends on battery type, stereo equipment, and how hard you play the stereo. Lots of factors in other words.
