Hi, I currently have a Alpine MRX-110 amp that runs 1130rms as tested @ 2ohms or 650rms @ 4ohms (Not 1ohm stable) and a 12" FI SSD Neo DVC 2ohm 1500rms (Xmax Coil w/ Stiff Suspension) in a 1.0 cu ft sealed enclosure. Should I run the setup at 4ohms or, buy a DVC 4ohm sub to run @ 2ohms or a 1ohm...
