My amp cuts off at high volume so I wanna try this old Rockford I have. Its for the interiors.2 infinity perfect fronts and alpines rear... my question is this amp is 35 rms x 4 @ 4ohms and 75 x4@ 2 ohms. My speakers are 4 ohms how do I wire them to 2Ohm and check everything before I power up with a digital meter
