Wiring for mono-blocks

. . . here are some examples of search results using "dedicated circuits" for a search engine:

dedicated circuit threads

I remember a couple of years or so ago it seemed like there was always a different thread/discussion going on related to dedicated circuits.  Either here in the preamps/amps forum or in misc.  Anyway, you might find some of those discussions interesting and informative, so if you use the 'search discussions' function up on the top of the page and try a search engine such as "dedicated circuits" (or something to that effect) I bet a lot of interesting results would come up.

Anyway, I have my amp, preamp, and digital source all on one dedicated 20A circuit, and I have tow dedicated circuits that I am not using right now. So I really think that one 20A circuit would do it for you, 

BUT,

as far as labor goes, the actual work of putting three circuits in (which is what I did) is not a whole lot more than putting one circuit in.  The Romex is an added expense, but still, it I was going to put one in, I'd put at least another one in, and that would give you some flexibility to experiment with.

As far as the hum and "interference" (RFI?), that might be cleaned up simply by having a dedicated circuit.  As I typed in my first paragraph, there is are a lot of great threads on the subject.

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.

Oh, sorry, I assumed you were bridging a pair of mono-blocks.

it's a stereo amp, bridged, thus two stereo amps bridged into a pair of mono-blocks for a pair of speakers, why didn't you say so? Heh.

Still, you should not be tripping breakers.

To keep cables the same length, I would run three sep. ckts. 1 located for each amp near each speaker and 1 for the system source components: actually one 15 amp for a power controller, like the Furman P-1800 (PF R version)

Furman P-1800 PF R

a pair of bridged amps drive a SINGLE speaker, how can you say bridged and driving two speakers?

something is wrong, no way should you be tripping breakers,
