    How much power does it consume at the wall and how much would it be if I buy 2 of them.

      When idling the amp will use about 15 watts. Total power usage Will depend on the volume level. A 20 amp circuit breaker will be fine. 30 amp circuit breaker if you plan on really pushing the amp hard. Please contact us directly at sales@classdaudio for pricing information.
