$5,000 in audio equipment and you're telling the guy to knowingly overload a circuit in his house in the hopes of MAYBE they wont draw enough power to trip the breaker? Awesome.
Clearly money isnt an issue here, so take the time and do it right. Add a circuit or 4 into the room. The wall behind our TV consists of 4 sets of outlets, each on its own breaker.
* Overloading a circuit will trip the breaker. Tripping the breaker is what protects
the wiring from the real overload that heats up the wire and if hot enough, can
cause a fire. You can overload a circuit all day if you want provided that is has
the proper circuit breaker.
* I'm not telling him to overload a circuit, rather you install the system and try it out to see if the breaker really trips. Music has a low duty cycle and power consumption is much less than looking at rms values. People make this mistake
daily on every forum, judging electrical needs based on rms values.
* If there is a problem, install a new electricial circuit or you can just run
an extension cord into a different outlet on a different circuit to operate the
system. Extension cords are used to power equipment that have short cords,
that's why they are called extension cords, lol.. They aren't meant to be permanent installs, rather temporary use as we don't want extension cords
running all over the house. But because you used them, doesn't mean a hazzard
is more likely to happen vs. the same guage wire installed behind your drywall //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif ... The same laws of science apply to wires outside the walls
as they do inside the walls.
Each BP7000SC combines a new built-in 14" SuperCube® subwoofer driven by an 1800-Watt class D amplifier, two pressure-driven 14" infrasonic radiators and bipolar dual D’Appolito front and rear mounted driver arrays each consisting of two high-definition cast-basket 6-1/2" Definitive bass/midrange drivers surrounding a 1" annealed pure aluminum dome Definitive tweeter.
One circuit can easily operate this.
* 1800w class D amp playing music won't taxi the circuit too much. Playing test tones will draw alot more current.
* A few 6" mids and 1" tweeters won't taxi any electrical system even if you connected a monster amp to them.
