I just picked up a ia 20.1 but i was reading and i guess there is 2 versions. What are the differences like how do i know which version i have also what kinda power do these produce.. I have all 0 gauge and one of the big c&D batteries in the trunk with my db 2000.1 I didnt drop below 13 volts was just wondering what i could expect to be getting with the ia 20.1
