Hi Folks,

I'm working on a 12v deep cycle battery based sound system for a friend. Obviously the efficiency of class D amps could be quite useful. What I'd like to know is:
- what class d modules are particularly suited to 12v rails
- if any of the above are stable into a 2ohm load

The lazy solution would be a couple of the dayton tripath amps, but I imagine there's probably better options out there.
 
Any Tripath 2020 based amp is optimal as they are 2 Ohms stable with sufficient cooling. The Dayton is not suitable for your use as it's not 2 Ohms stable, and it's also too expensive in my mind compared to paying a little extra for one of the much better Tripath 2020 based amps out there (41Hz, Topping, Hlly and so on).

See link in sig for ideas/solutions. :D
