i may be getting a elemental designs 13ov.2 dual 4 ohm i was wondering if this amp i was gonna get will be able to do its full 400w on it. its a Phoenix Gold X400.1. the amps specs say 400W x 1 (4-1 ohm) so i think im good right? or do i have to wire the sub a certain way to make it 2 ohm? thanks for your help!
