Hi I have four Crossfire DB12D2's i bought off my friend. They came with 2 Distinct Audio D600 2 channel amps but they are only 125 RMS at 2ohms and the subs say dual 250W RMS so im assuming thats 2ohms? Anyways would i need to get 1000watts RMS at 2ohms to power the subs to their full potential or how would i do it? If you could maybe link some good amps that would work id appreciate it. Thankyou.
