How could I hook up a 4 Ohm Sub and a 2 Ohm Sub to an amp?

Question

I have one sub that is 2 Ohm and one that is 4 Ohm. They are both Alpine Type R's. How/Can I wire them correctly to an KAC-9103D Kenwood amp?

Answer 1

Do not attempt to hook up two different subwoofers of different ohms.

On the other hand, one of those Type R's by itself would sound excellent! The amp you are running would be fine.

*4ohm sub* To hook up the 4 ohm sub, connect the positive from one voice coil to the positive to the other voice coil, and then connect that to the positive on the amp. Do the same by connecting the negatives, and connect them on the amp. That will run one of them at a 2 ohm load that the Kenwood says provides 900 watts.

*2 ohm sub* You cannot run the 2 ohm sub at 2 ohms when it is dual voice coil. To wire the 2 ohm sub tho, connect the positive from one voice coil to the negative of the other voice coil. Then take the left-over nagative from one voice coil and the left-over positive from the other and connect those to the proper positive and negative on the amp. That is a 4 ohm load, which the Kenwood says provides 500 watts.

My opinion, I think wiring just that one 4 ohm sub to a two ohm load on the amp will be extremely satisfactory. The Alpines Type R's are quite impressive for the cost, and handle fair amounts of power. I don't think you need two of those on that amp anyways. Hope it works out!

Answer 2

never put subs of different impedences on the same amp
