What gauge of speaker wires do I need?
Yamaha RX-V550 6.1 receiver (90W x 6 but sounds like more)
The center speaker is no more than 4 feet.
Both fronts no more then 10 feet.
For the rears I will have to take it thru the attic:
The left, right, and centers 60 feet at most.
My question is do I need to buy seperate gauges for the fronts and the rears? Or can I just run one size gauge to all? Also, will 12 gauge be enough for the rears or should I go 10 or even eight. Can anything negative happen if I go too low on the gauge of cable?
Please do not mention Monster cables or specific name brands. Just the gauge. Thanx!!
