Wiring for mono-blocks

Hi - I have two Krell KAV-250a’s that are bridged (so they are 1000w each) powering two Definitive Tech BP-2000 floor standers. This setup puts serious strain on my existing home wiring. I currently have each amp running to outlets on separate breakers with long outdoor single plug power cords in order to prevent tripping breakers. I want to have dedicated outlets installed near the  set up but am not sure whether I need one dedicated 20 amp for the set of amps, or two dedicated 20 amp outlets (one for each amp)? Or something else? If I use one dedicated 20a would I use a power conditioner to reduce hum/interference? Thanks!

rkosar,

I have 3 dedicated circuits. All with 10-gauge wiring terminated with Furutech NCF outlets. I have one circuit for my Video, one for my Subs (4 JL F-113) and one circuit for my Audio System. All have 20A breakers.

Within the Audio system is a Niagara 7000. This unit has both of my Michi 8 amps plugged into it along with a few other items. These Amps are rated for way over 1000 per channel. If they ever used that much power, it would probably blow my ears off...

So, 1-20 Amp circuit should suffice nicely with your amps. Perhaps a second line for your other audio equipment.
