How many feet of speaker wire do I need?
The rule is the total resistance of the wire should be less than 5 percent of the rated impedance of the speaker. Your Insignias are 8-ohm speakers, which means 16 gauge is good for up to a 48-foot run (per speaker). Speaker wire of 14 gauge is good for an 80-foot run, and 12 gauge is good for 120 feet.
What size wire should I use for subwoofers?

Can I use a 40 amp breaker instead of 20?
The answer is, “No, do not put a 30 Amp breaker in place of a 20 Amp breaker because the wiring is most likely’sized’ for the 20 Amp load and -may- overheat if a 30 Amp load is used with wiring sized for a 20 Amp load.” …
Can I replace a 40 amp breaker with a 50 amp?
The majority of residential ranges only need a 40 Amp circuit. Interchangable are 40 and 50 Amp breaker/circuit. It is possible to use either for a 50 Amp receptacle.
Can I use a 40 amp breaker instead of a 30 amp?
A 30-amp circuit uses wiring that can only handle 30 Amps of electricity, which means anything over 30 Amps flowing through that circuit will cause the wires to heat up. A 40-amp breaker could potentially allow unsafe levels of electricity to travel through that circuit and never trip until the flow reaches 40 Amps.
