Re: Shorter extension cords or shorter speaker cables?I'd agree with accepting some loss rather than leaving the amp in a compromised position.However, a 100' run of 12 gauge wire results in only about a 4% loss of power on an 8 ohm speaker, or 8% for 4 ohm, or 16% for a 2 ohms load.A 16% loss would be about one dB less level, but the reduced damping factor from that length and gauge could make it sound like a greater loss than the power loss would suggest.
