i have a dd 9515 dual 2 ohm. wondering what amp to go w/. right now i have a jbl 1200. i would be running it at one ohm. i was wondering about the dd amps. like do they require a lot of current, what's the real output of them too. alos thought about a shredder and running it at 4 ohms (mainly b/c of current draw would be too much at one ohm).
