The Alpine Type Rs , in either 2x2 or 4x4 , id only be running one , so w/ the 2x2 id run in series for 4ohms , and the later in parallel at 2 ohms , ive got an Infinity Beta Digi 300 w/hich in mono is good for 1k watts RMS @ 4ohms is stable down to 1 ohm , would SQ differ between the 2 different loads ??????
