I use a 30 amp dedicated circuit. It is in my ex-laundry room, which now is my equipment room. The speaker wire runs through the wall behind this stuff. The transformers in my amps can draw 2000 watts, so a standard 15 amp circuit is out of the question, and a 20 amp dining room, kitchen, garage, washer, is not enough. If your amps have small caps and/or do not have regulated power supplies, a power conditioner can emulate such for your system. My amps have 16 26000 mf caps (4 per channel, bi-amped), with the 4 500 watt trannies, plus a chip regulated supply, so it is not an issue.
