The peak current value of an amplifier is the maximum amount of current which output is capable of sourcing for brief periods of time.
Instead, you should look at the maximum power consumption specs to determine if a 15amp line is sufficient.
For 5250, the maximum power consumption is 2500watts,
the 2003 maximum power consumption is 1320watts.
2500watts / 120volt = 20.8amp
1320watts / 120volt = 11amp
It is best to run each amplifier on separate 20amp and 15amp line if you drive them to maximum rated power.
However, unless you use them to drive very low efficiency speakers in a very large room with high volume level, I believe it is OK to use a single 15amp line to both amplifiers as long as they do not tripping the circuit breaker.
