The question: I want to run an ati 2505 and a Velodyne HGS-18 sub, along with the other ususal home theater suspects, on a standard household 20 amp circuit, with a 20 amp wall plug. Can I do it, and still get the current necessary to drive the amp and the sub to spec? The ATI rep said that a 20 amp circuit and plug would be plenty for the amp, but I forgot at the time that I'll be driving the sub off the same circuit, so I didn't ask him about that. Problem?
I demoed a pair of reQuests and a Cinema center channel a few weeks
ago (waiting for reQuests, Logos and Scripts to arrive now) using
my ATI 1505 and Sony TAE9000ES. I have a set of 6 track lights
that are using ~100W bulbs. When I had the volume at my standard
level (intense, but not insane) the lights were dimming to the
beat of the music. I also had an NHT SW2P sub and a 35" TV plugged
into the same wall on different outlets, but it was all probably on
the same circuit. My plan is to run a new 20A circuit for the amp
and speakers (I have to put outlets in the ceiling for the Scripts
anyway). I just ordered a Sunfire Cinema Grand (didn't know I was
buying ML when I bought the 1505 1.2 months ago) to give the ML's
a more 'stable' amp for its wide range of impedence. Its increased
output may require more current than the ATI.
I forgot to mention that now I will have a Velodyne FSR-18 on the
same wall, so I feel I MUST run a new circuit. to accomodate all
this new equipment.
Unless you are going to crank the living hell out of your setup to volume levels that would damage your hearing after 10 seconds. 20 amps at 120 volts is: 2400 watts!! The owner's manual *should* state how much power the piece of equipment will consume at idle and when driven to its maximum output.
Have fun,

20 A is a lot of current ... even assuming a low 2 ohm load, it delivers all of 800 watts.
