Gauge Wire Faqs

Q.  Should I purchase aluminum wire or copper wire?

A.  Copper is the best purchase.  Aluminum is an option when the wire on an overhead line, because it is 50% lighter than copper, and when the feed line is quite large; to save money.  Always try to go with copper first.

Q.  Does high quality speaker wire sound better than low quality speaker wire?

A.  Yes, it does make a difference.  The largest difference is getting something that can carry the full amperage of the receiver, speakers, and amplifiers.  Make sure that you get wire that has 20% more capacity than what your maximum use will be.

Q.  How do I know what gauge of wire to purchase?   

A.  You can add up all the watts being used on the circuit and then divide by volts used (110 or 220) and that will give you the amps.  Then, look at a chart on the home page to see what wire can handle that many amps.  If in doubt, get something larger than what you think you might need.  It doesn’t hurt to have extra capacity.

Q. What is stranded wire?

A.  Stranded wire is a whole bunch of smaller wires twisted together.  The main reason to get stranded wire is for flexibility.
