All four in parallel is 1 ohm, which many amplifiers are not stable into. Coils paralleled per driver with the drivers in series, or coils in series per driver with the drivers in parallel, both land at 4 ohms and that is the sensible target. Alpine's 8 AWG push terminals and voice coil jumpers let you make the change at the driver. Aim for 600 to 1200 W RMS total at the final impedance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eBuilt in Tennessee, Backed by Audio Intensity\u003c\/h2\u003e\n\u003cp\u003eCut and assembled in Tullahoma, Tennessee on our own CNC equipment.
