4-ohm subwoofer?

Question

Where do I connect the jumper?
I have one amp (alipine mrp-m650)
one subwoofer, type S 4 ohm.

Answer 1

Match the red jumper with the red the red terminals and the black jumper with the black terminals and then hook up the speaker wire to the red and black terminals - then turn up the volume and see if it works! If it blows up or puffs of gray smoke come out of the wires, then nevermind...I was wrong!

Answer 2

Is it a single 4 Ohm or dual 4 Ohm? The m650 will work well at 2Ohms so take the red jumper and stick it in the ends of the red terminals and take the black jumper and stick it in the ends of the black terminals and then hook up the speaker wire to the red and black terminals on one side.
