How can i make my sub woofer stronger?

How can i make two speaker wires sub woofer to a sub woofer RCA connection?

• i have a sub woofer that has speaker wire which has two connections the black and red and hooked up to my receiver. i wanted to hook it up to my other receiver but it only has one RCA black input. i went to radio shack and they told me i have to convert it some how but i don't know how if it is possible?

• Answer:

  Two speaker wires into a single RCA? Well its splicing time my friend! The negative wire from RCA is the one that is under first layer of insulation and the positive would be under the second making it a very thin wire and you will need to use care in order to strip it. If this is for the sub like you say then it should work out ok for you. Subs dont need fancy signal wires to sound good as long as its able to filter high frequencies out it will be all good. Time to upgrade to a receiver with the proper pre-outs though man. EDIT EDIT EDIT---- Just got a clearer idea of what youre asking and the above poster brings up a good point. IF this is what youre trying to do then STOP! The impedance on the sub from a home theater in a box will rarely be the same and will definitely be lower and probably 3 ohms causing a heavy load on the amp that is designed for 8 ohm speakers. If you are trying to hook the sub up to the receiver through the preamp on the receiver dont bother as the sub from the HTIB will not have a built in amp and will receive nothing but a signal from the receiver itself or in Jethro tech talk- You aint gonna get no boom for the boom box!
