Speaker wire probably. What type of subwoofer do you have? |

Yes.
The correct answer depends on your speaker, your sub, your room and your tastes. The most common thing to find in subs now days are powered subwoofers with their own amplifiers. These take a speaker line in (usually, make certain anything you buy has this provision). You can either run you current speakers full range or roll them off in the lows by using the crossover circuitry built into the sub's plate amplifier. If you buy a passive sub, you can run it from your existing amplifier's speaker outputs.
Most people consider the powered sub a good choice since you can roll off the lows from your main speakers and they have less work to do. In theory this means they will be cleaner in the range they cover. Try a sub and see what you think. A decent audio shop can help you along. What's the budget?
