How many feet of wire will I need to make my new speakers be the same volume as my old ones?
I recently bought some new bookshelf speakers to comnpliment some floor speakers in my home theater system. The news speakers can output 100 watts and are 4 ohms, and will require a mininum of 15 feet of wire. The old speakers can output 100 watts and are 8 ohms, and will require at least 10 feet of wire. The wire I’m using is 16AWG. Each set of speakers will be about three feet from the listener. My question is, how much wire will I need to run to each speaker to make them have the same volume, and how can I calculate this?
I should have been more specific. There are a pair of 8 ohm speakers (front) and a pair of 4 ohm speakers (surround). Each of these have a maximum of 100 watts.
The reciever itself does not have a way to adjust the volume on a specific speaker, just the system as a whole.
You can’t. Speakers don’t output watts, unless you are talking about professional units, and 100 acoustic watts would deafen you pretty quickly..
You should worry more about your impedance. A 4 ohm and an 8 ohm paired will make somewhere around 2-3 ohms, which might fry your amp. You can go into a switching system, and then add volume controls if you really, really must match levels.
Also, nothing you have said indicates relative level. If you are using a home theater receiver, there should be level controls in the setup. If these are the back channels, just use those to set levels.
Place your speaker where U want. Measure the distance for the wires to run from the receiver to the speakers. Adjust the listening distance with your receiver.

In most cases, the length of speaker wire will have no bearing on quality of sound or volume.
Quality of speaker wire can make a difference.

You must not run 4 ohm speakers with 8 ohms amp, the other guy was right, you can burn your amp.
Buy a new pair of speakers for your rears that match your amp impedance or try to switch them with somebody.
Also, check the spec of the speakers, 4 ohm is the used imp in car audio; that could be a use to give them.
Good luck
