I'm ordering two Motion Lab stringers today.
4 duplex edisions, a 20a powercon IN, and a 15a breaker.
I figured this would be the logical progression for the system.
as I grow I'll add more stringers when I'm ready to make the leap to a bonafide distro.
For two years I've been running the whole rack off two 15a breakers and have (once or twice) popped breakers.
Given the power use critera for the amps it still amazes me.
Xti 4000 1/3 power 4 ohms 18.9a 1/8 power 4 ohms 9.8a
Xti 2000 1/3 power 4 ohms 12.5a 1/8 power 4 ohms 7.6a
Xti 1000 1/3 power 8 ohms 6.8a 1/8 power 8 ohms 4.6a
Xs 1200 1/3 power 8 ohms 13.5a 1/8 power 8 ohms 7.6a
Which added shows Stringer 1 at 1/8 power maxes out at 29.5a
Stringer 2 at 24.9a
And 1/3 power equals Stringer 1 51.7a, Stringer 2 43.9a.
The 15a breakers in the stringers are SPL watchdogs.
